Challenges of Merging Messaging between Tenants of Office 365November 27, 2018
Picture this: You’ve just acquired two companies, and all three of you are running different tenants of Office 365. So you need to merge everyone under the same umbrella, to a single tenant. And you need to do it fast.
Unfortunately, it’s not the easiest thing to do. There are some unique challenges that come with merging tenants of Office 365. Here are some of the challenges you might face , along the way.
Share a single email domain
Day 1 of a merger is critically important. This is the first day where the merging organizations start functioning as a single entity. Which means that, at a minimum, you need to get everyone on the same email domain (example: @binarytree.com). But when it comes to migrating between Office 365 tenants, this is easier said than done.
With a bit of work, you can use current solutions on the market to move domain names in one tenant to a new target. The problem is, this will require some problematic downtime in which email won’t come through—or even be sent.. Your team might miss something critical, or at the very least, you might face slow productivity for a bit. This isn’t ideal when you’re in the middle of a merger, things are moving at high velocity, and emotions are already running high.
Ensure rich collaboration
Also on Day 1, you probably want your users to collaborate as smoothly as if they were already on the same tenant. That means being able to look each other up in a shared directory, share calendars, and see free/busy times. That will help drive productivity and foster a collaborative, high-functioning organization. To make this happen today, you’d have to use on-premises Active Directory accounts and write manual scripts. It’s challenging and time-consuming, with a high risk of things not working quite right.
Sync the old and new email accounts
Of course, you can’t just forget about the old email addresses, as people will keep sending email to them. Also, your users might still need to send email from their old address. So you need to keep the old and new email accounts in sync. Users should be able to use their new email account to seamlessly send and receive emails from both accounts.
With today’s options, that’s not fully possible. As a workaround, you can forward email from the old mailbox, which takes care of part of the problem. But in Office 365, it’s still impossible to send email from a new mailbox using an old address. So, if you take the time to manually set up a forwarder, it’s a lot of extra work—for incomplete results.
Automate migration steps
As you move the old email accounts to the new environment, you’ll want to automate as many steps in the process as possible. For example, when you get the new mailboxes set up, it’s time to disable the old mailboxes in the old environment. As of now, there’s no quick way to do it. Existing solutions make you do this manually, which leads to even more time and effort and a higher risk of mistakes. Adding all of that extra time up for all of these results, and you’re left spending a lot of effort that should be able to be automated, right?
So those are the challenges. What’s the solution? Our Power365® is the first tool that gracefully bridges two or more tenants of Office 365. It solves all of these challenges—and more. You can use it to share an email domain, directories, and free/busy calendar information. All while keeping users on separate tenants for as long as you need.
