As many readers will be aware, Microsoft’s Ignite conference starts in Atlanta on September 26, 2016. I am speaking at a number of sessions. Possibly my favorite is the opportunity to debate Greg Taylor from the Microsoft Exchange development group on the topic “The Top Ten reasons not to move your Exchange on-premises mailboxes to Exchange Online“. The debate will be chaired by Steve Conn, who might have quite a task on his hands as those who have seen Greg in action in the past understand how excited he can become. I’ll be the calm, logical one with the scintillating comments. Or not. We’ll just have to see.
In any case, we need to understand the reasons why people might choose to leave their mailboxes on-premises so that we can debate the rationale and reasoning. I’ve put together a list of the most common reasons I know of and would appreciate your help in recording others, if they exist. Please reply to this topic with your reason and we’ll add it to the mix.
I doubt that we will get to debate more than 10 topics during the 75-minute session… But you never know!
Thanks for your help

Backup and recovery
- Microsoft uses Native Data Protection and doesn’t take backups of Exchange Online data. I like to have the security of backups, just in case an administrator or a user does something stupid – or we are hit by a ransomware attack and have to restore some mailboxes.
Stability and robustness
- Our Exchange 2013 infrastructure delivers better availability to our business than we believe is possible from Office 365, especially with all the horror stories we hear about multi-hour outages for essential components like AAD and EOP. The SLA results as reported by Microsoft are accurate for the entire service but don’t reflect the experience of individual tenants.
- Our server infrastructure is modern, we’re up to date with Windows Server, and we think we have a highly cost-effective platform for the next five years.
- Exchange 2013 and Exchange 2016 are feature-rich email servers already and Microsoft is doing a good job in transferring some excellent technology from the cloud, like Managed Availability, simplified DAGs, and automatic DAG activation. We don’t need anything else.
- Our Exchange admins are the best in the business and have our Windows servers humming beautifully. Why would we plunge into the unknown world of Office 365 and all its component parts?
- When a problem happens inside Office 365, it seems like no one knows what is really happening and you have to fall back on Twitter and Facebook to gain some insight into how widespread the problem is and when it might be resolved. That’s an unacceptable state of affairs for our business. In other words, monitoring and reporting for Office 365 to understand the current state of affairs on a minute-by-minute basis is poor when compared to what we can do inside an on-premises environment.
- We’ve heard that the Office 365 support is pretty poor at times and you have to wait before you can get to speak to someone who isn’t reading off a script and might actually be able to help. That’s a big concern when you consider moving from a tightly managed and well-supported on-premises environment.
- We want to use our own keys with Exchange and AAD RMS and Exchange Online doesn’t support BYOK. In other words, I don’t trust Microsoft to protect the privacy and security of my organization’s email and documents, if we let them own the encryption keys.
- The fact that the Office Graph records every interaction between Office 365 users is downright scary in a “big brother” kind of way. There’s no way that my users want or need to know the kind of information that Delve Analytics reports.
- My Microsoft sales person is selling Office 365 because they are compensated on that basis. They’re not interested in listening to our desire to remain on-premises and that makes us believe that the move to the cloud is great for Microsoft and probably less good for us.
- We don’t trust the costs cited by Microsoft for Office 365. You start off with a low monthly cost but then need to spend more to get the functionality that you really need, like AAD Premium or a high-end plan. We also think that you have to spend a lot of time managing licenses to make sure that you’re not overpaying for unused licenses.
- There’s no guarantee that Microsoft won’t increase the costs of all the bits we need to buy to create our Office 365 environment at a higher rate than inflation to achieve their goal of a $20 billion annual revenue run rate for commercial cloud products by mid-2018.
- Exchange is the fulcrum of an ecosystem we have constructed to serve business needs. To move to Office 365, we’d need to do a heap of redevelopment to make sure that Exchange Online delivers everything that we need. That work costs money.
- Giving users a standard 50 GB mailbox quota only encourages them to keep stuff that they should delete immediately. If we want to give 50 GB quotas, we can, especially now that storage costs are so low and Exchange 2016 does such a good job of supporting JBOD.
- We have users in some pretty remote places where Internet access is not great. The cloud’s not for us.
- Office 365 requires customers to keep software components at a far more recent level than we are accustomed to on-premises. It seems that we would be constantly updating Exchange 2016 to maintain support for a hybrid connection or Outlook to make sure that clients can connect to Exchange Online. That seems like a whole heap of effort for not a lot of return.
- The rate of change inside Office 365 is too rapid and challenging for our business users to cope with. No one wants to see a new client interface every three months. We like the stability and robustness we can assure through our own deployment.
- Public folders are all the collaboration tools that any reasonable person could want. It will take us forever to move the data out of public folders and to realign business processes around new types of collaboration tools. That’s a real hidden cost of migration both in terms of getting the work done and the business disruption. We just can’t take that cost on now.
- There seems to be a lot of SharePoint wrapped up in Office 365. Who wants to go near that stuff?
Out of the box thinking
- I do want to move to the cloud and am thinking about migrating from Exchange to Outlook.com.
- We believe that Microsoft will fulfil their commitment to support Exchange 2016 until 2025. Why would we ever move until they stop supporting on-premises software?
- If we migrated to the cloud, Ross Smith IV and Greg Taylor would hate us very much and that would be no fun.
