old user has on prem mailbox.

[chazzy2501]

We migrated 3 years ago, an old member of staff has come back. I enabled their old active directory account and the office 365 dutifully created an account but the mailbox won't be created as it states they have an on prem mailbox.

 

How to fix. (as local exchange server was removed years ago!)

 

I just want it to create a new online mailbox.

Have a look at this:

You need to modify a couple of AD attibutes, related to msExch.

I've done this with quite a few users, always get there in the end!

The home address was already not set. I cleared all attributes I could relating to msexch and we'll see what happens.
