hasToday’ post will help with Exchange migration errors, The source email address couldnt be found in the on-premise domain ?
The issue:
I have seen plenty of Exchange migration errors, many of them are transient errors and are a great big massive pain.
Sometimes, these errors are just the backend system having a wobble, and restarting usually fixes it.
This particular Exchange migration error, I found while performing a cutover migration in Exchange 2013 ready to migrate to M365.
The source email address couldnt be found in the on-premise domain
The resolution:
Another nice and easy, but not obvious one, its all to do with the GAL! (Global address list)
This can easily be rectified by using the following powershell command:
Set-Mailbox -Identity [email protected] -HiddenFromAddressListsEnabled $false
You can do the opposite and hide an address using $true if needed for something else, like so:
Set-Mailbox -Identity [email protected] -HiddenFromAddressListsEnabled $true
After waiting a few minutes, this allowed me to continue with my cutover migration batch, ready for the migration to M365 ?
As previously stated, there are lots of reasons for a migration batch to throw up errors.
