A closer look at Hosted Exchange from Microsoft

emailisemail“Email is Email!”. This is what another Microsoft partner suggested to me, that I should say when presenting Office 365 to potential customers. He went on to say “A customer is not going to make the move to Office 365 for email, it will be for all of the other capabilities”. Well, he was absolutely correct. Using his sound advice, Forceworks has brought thousands of business users to the Office 365 platform. But I continued to have this nagging feeling, that even though users are coming on board at a rapid clip,  I was short-changing Exchange Online in the process.

While it is true, that for most small and medium-sized businesses, email is simply… well, email, but for some, the differences are stark and should be known. So I decided to attempt flesh out exactly what Hosted Exchange is bringing to the table. In other words, Email is not Email, not even close. No more than a Car is a Car or a House is a House.

Of course, this conversation starts with where you start, and those points are vastly different. For most of our customers, Hosted Exchange (or Exchange Online as it is known) comes in as part of their Office 365 subscription. It is just a piece of a package that may also include Lync Online, SharePoint Online, Office, Dynamics CRM Online, Project Pro Online, Office Web Apps, etc. While together these make an undeniably superior solution to whatever most clients may be using today, Exchange Online alone is worth the price.

Business users today have their mail served from a wide array of sources, all with varying degrees of capability, performance and security. POP Accounts (thankfully fading away), webmail, Gmail, Yahoo Mail, proprietary vendor email systems, on premise email systems, and increasingly over the last decade, Exchange hosted by a provider. Of these options On-Premise Exchange has long been considered by IT the best choice for those who could afford the infrastructure and administration. The second best IT choice was a Hosted Exchange provider, think Rackspace, Intermedia, Sherweb and hundreds of others. Suffice it to say, if you are not using Exchange, either on-premise or hosted, most IT professionals would agree that you are using something sub-par, on multiple levels. So really there are two camps, Exchange Users, and everybody else.

Microsoft, of course, “owns” Exchange. They wrote it and launched it in the early 90s, and have been building on it ever since. Microsoft offered this software initially to businesses for their own use and later also to other businesses who would  “build a business” by hosting the software on their own servers and offering Exchange Email service to business users. In April of 2009 Microsoft launched Business Productivity Online Services (BPOS) as their first foray into offering Exchange as a hosted service themselves, but it was not until the re-brand and re-launch as Office 365 that users started to really take notice. And not just users, but the other hosted Exchange providers as well… and they were not too happy. Maybe if Microsoft had priced their service above the cost of the providers reselling their product things would have gone smoother, but in almost every case, Microsoft was cheaper.

MicrosoftDublinDataCentreAerialViewFrom a  provider perspective, Microsoft was, and is, directly competing with them, but without the provider’s cost burden of licensing the Exchange software. It is an interesting situation, paying your competitor to use their software to compete against them. It might have been surmountable, had Microsoft not gone and built all these state-of-the-art data centers. Microsoft did not build these data centers to cause problems for the Exchange Hosting providers, they built them for their entire cloud strategy which is much more encompassing than just email, but the result is the same. No other email provider, of any type, comes close to what Microsoft has behind Exchange Online. For email alone, they could never justify the cost. From a user perspective, they can get Exchange from the owner of the software, running on superior data centers for a lower cost… Darwinian indeed.

So let’s get back to on-premise exchange otherwise known as Exchange Server. By the way, Exchange Server is the same software that the third-party hosting companies have. Microsoft’s Exchange Online, while also running Exchange Server 2013 has quite a few capabilities and features that are not available at all, or at least delayed for the on-premise version, and therefore the hosting provider’s versions. So if you are an IT Manager with on-premise Exchange Server, you are probably smiling that your organization was not involved in the hosting issues described above.

While the battle rages on, you sit comfortably on the sideline, literally Master of your Domain. We hear it all the time, “We have on-premise Exchange, it has all we need and never goes down”. On the first part “has all we need” you are either oblivious or in denial, and on the second part “never goes down” you are lying. I have written at length about IT’s fears of loss of control, or worse loss of a job. The more I talk about the breadth of solutions that Microsoft has in their cloud stack, the greater this fear becomes. So let’s forget about all that and just talk Email.

The typical midsized business with an actual IT department usually has a rack of servers, either literally on the premises or at a private data center or both. Among these servers, many workloads are taking place beyond just email: file shares, accounting software, ERP, anti-virus, too many really to list. But in looking at the email function in particular, it is impossible for IT to be heroes. Email is assumed, like air conditioning or electricity, nobody even thinks about it unless it goes down. When this happens, IT bubbles up from being out of the users’ minds, to a bunch of freaking idiots. Your heroic efforts to restore service are neither appreciated, or even thought about two seconds later.

From an IT perspective, Email presents nothing but risk to your department and its internal reputation. And for what? The perception of control? The impression that you have a better ability to keep it up than Microsoft? I would compare Microsoft’s uptime record for Exchange Online, to any IT department in any midsized business. So even if there were no other reasons, this alone should be reason enough to get out from under email, but there are other reasons.

spamcanLet’s take a quick look at just one important feature, anti-spam. I am going to make the assumption that you not only have Exchange Server, but you also have Forefront protection, which I know many of you do not. Exchange Online Protection (EOP) is the next version of Forefront Online Protection for Exchange (FOPE). EOP anti-spam protection features are included in Exchange Online. The following are benefits of using Exchange anti-spam protection in the cloud (Microsoft Exchange Online or Microsoft Exchange Online Protection) as opposed to Microsoft Exchange Server 2013, which has most of the same built-in anti-spam capabilities as Microsoft Exchange Server 2010:

  • More control and easier configuration   Administrators can use the Exchange Administration Center (EAC) web-based management console in order to customize spam filtering settings so that they best meet the needs of your organization. There is no anti-spam user interface in Exchange Server 2013.
  • Stronger connection filtering   In Exchange 2013, connection filtering IP Allow lists and IP Block lists are available only if you install an Exchange 2010 or Exchange 2007 Edge Transport server in your perimeter network. In the cloud, you can choose to skip spam filtering on email messages sent from trusted senders (gathered from various third-party sources), ensuring that these messages are not mistakenly marked as spam. Also, the hosted filtering service uses Microsoft’s own block lists and lists aggregated from vendors to provide greater IP-level filtering.
  • Stronger content filtering   You can easily configure your content filter policy to:
    • Filter messages written in specific languages.
    • Filter messages sent from specific countries or regions.
    • Mark bulk email messages (such as advertisements and marketing emails) as spam.
    • Search for attributes in a message and act upon the message if it matches a specific advanced spam option attribute. If you are concerned about phishing, some of these options offer a combination of Sender ID and SPF technologies to authenticate and verify that messages are not spoofed.

    In addition to the above content filter options that you can configure in the EAC, the hosted filtering service uses additional URL lists to block suspicious messages that contain specific URLs within their message body.

  • Quicker updates   Spam updates are propagated more quickly across the network. In Exchange Server 2013 updates occur two times per month, whereas the service is updated multiple times per hour.
  • Outbound filtering   Outbound spam filtering is always enabled if you use the hosted service for sending outbound email, thereby protecting organizations using the service and their intended recipients.

This is only one aspect of email, anti-spam, but there are many others. On our Exchange Online product page we have a complete breakdown of the differences between Exchange Server 2013 and Exchange Online. Note that the differences are even more stark if you are on an earlier version of Exchange Server, but I am not showing all of those.

When is the best time to make a move?

This is a huge question with different answers depending on your situation. It also has a great deal to do with how much value you place on different feature and capability gains, which also varies from business to business. There is also a migration cost to consider. If you are currently on one of the other hosted Exchange providers it is fairly easy to do a cost/benefit analysis and make a decision. The challenge sometimes is getting past the misinformation that their desperate sales staff will spew as they try to keep yet another client from leaving their over-priced solution.

If you have an on-premise Exchange Server the trigger points are much different. We often find companies making the move when either hardware or software upgrades are required in order to avoid that expense. This is a very pragmatic approach that completely discounts the additional value received, but the C-Suite has usually looked at IT as an expense to be managed rather than a value creator.  Sometimes a move is triggered by a failure of something that creates downtime, or spam issues. This is not the best time as undue pressure may be placed upon IT, but the fact is that many migrations are reactive rather than proactive.

I encourage you to look into Exchange Online… thoroughly and objectively, then contact us to discuss your situation, we are here to help.

@ThingsExpo Stories
Countless business models have spawned from the IaaS industry – resell Web hosting, blogs, public cloud, and on and on. With the overwhelming amount of tools available to us, it's sometimes easy to overlook that many of them are just new skins of resources we've had for a long time. In his general session at 17th Cloud Expo, Harold Hannon, Sr. Software Architect at SoftLayer, an IBM Company, broke down what we have to work with, discussed the benefits and pitfalls and how we can best use them to design hosted applications.
Most of the IoT Gateway scenarios involve collecting data from machines/processing and pushing data upstream to cloud for further analytics. The gateway hardware varies from Raspberry Pi to Industrial PCs. The document states the process of allowing deploying polyglot data pipelining software with the clear notion of supporting immutability. In his session at @ThingsExpo, Shashank Jain, a development architect for SAP Labs, discussed the objective, which is to automate the IoT deployment process from development to production scenarios using Docker containers.
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Summit, Charles Kendrick, CTO and Chief Architect at Isomorphic Software, demonstrated examples of com...

The Internet of Everything is re-shaping technology trends–moving away from “request/response” architecture to an “always-on” Streaming Web where data is in constant motion and secure, reliable communication is an absolute necessity. As more and more THINGS go online, the challenges that developers will need to address will only increase exponentially. In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
Two weeks ago (November 3-5), I attended the Cloud Expo Silicon Valley as a speaker, where I presented on the security and privacy due diligence requirements for cloud solutions. Cloud security is a topical issue for every CIO, CISO, and technology buyer. Decision-makers are always looking for insights on how to mitigate the security risks of implementing and using cloud solutions. Based on the presentation topics covered at the conference, as well as the general discussions heard between sessions, I wanted to share some of my observations on emerging trends. As cyber security serves as a fou...
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
Container technology is shaping the future of DevOps and it’s also changing the way organizations think about application development. With the rise of mobile applications in the enterprise, businesses are abandoning year-long development cycles and embracing technologies that enable rapid development and continuous deployment of apps. In his session at DevOps Summit, Kurt Collins, Developer Evangelist at, examined how Docker has evolved into a highly effective tool for application delivery by allowing increasingly popular Mobile Backend-as-a-Service (mBaaS) platforms to quickly crea...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
