Return to on prem Exchange

Hello, I have a client that was converted to Office 365 a few years ago, and they're looking to migrate back to an onprem  Exchange solution.

I recommended against it, but they're moving forward and wanted to know what the process for migrating off would be?

I'm not familiar with this process and would appreciate any help. Thank you!

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Best option will be to setup hybrid, with the dirsync soft-match functionality it should allow them to move the mailboxes back to on-prem. But it depends on what the previous setup was and many details. More info here:

Another approach will be to use the PST capture tool:

The problem with it is that you cannot export cloud mailboxes to pst via PowerShell, you will have to do it on a per-mailbox basis via Outlook.

There are some third party tools to assist you with this, such as MigrationWiz. They come at a price :)
