O365 email address write back

[dapaulio]

Good evening

Before we moved our exchange mailboxes in to exchange online the email address in AD was written back to when the mailbox was created.

 

Now we have move all mailboxes in to exchange online this attribute is no longer automatically populated.

 

We use AAD sync and We have a third party that syncs it database based on this field in active directory and it causes problems with their sync when a new user is created in ad, unless we remember to manually enter the email address of the user.

 

Is this a limitation of exchange online not syncing back to ad or have i over looked a write back setting in adsync

 

TIA

You need to add the email address into AD, ADSync is only one way.

There are tools or Powershell commands that can do this for you in bulk though, so not too onerous if you’re doing loads of them!
