The Issue:
So while working on a new Exchange Migration project, I have encountered a weird issue where I could see users migration batch status complaining about being stalled due to (Big Funnel).
The error is showing as in the below screenshot and it doesn’t occur instantly after you start the migration of the user but right after it starts.

The Microsoft Exchange Mailbox Replication service was unable to save changes to request.
Request: ‘9a444721-80e2-4cf8-8c81-8a3afe3dc775’ (bbc2c66e-857e-4ba6-8462-9d66da73d400)
Database: DB01
Error:
The request has been temporarily postponed because a database has failed over. The Microsoft Exchange Mailbox Replication service will attempt to continue processing the request when capacity becomes available on the new server hosting the database.
Looking at the event ID number 1114 it mentions there seems to be an issue with the request seems there might be an issue with the mailbox being moved.
To dig deeper I am going to search some of the users reporting the same error by using their GUID
The property “DisplayName” with value “User LastName” is invalid. The value can’t contain leading or trailing whitespace.
Solution: (For a single user)
To resolve the problem, I am going to remove the trailing space in the end of the display name. You can safely use the below Powershell script to solve this problem however, if you don’t trust yourself or you’re not familiar much with Powershell, You can try it on a lab or a single test user for instance.
Get-Mailbox -Identity USER | Foreach { Set-Mailbox -Identity $_.Identity -DisplayName $_.DisplayName.Trim() }
Solution: (For all users)
Get-Mailbox | Foreach { Set-Mailbox -Identity $_.Identity -DisplayName $_.DisplayName.Trim() }
Some relevant errors you might encounter as you’re moving users to Exchange 2019
