Hello everyone,

 

In our environment, we have 4 Domain Controllers in DC, 2 Domain Controllers in DR, and exchange server 2016 with stretched DAG (2 MBX in DC and 2 MBX in DR site).

 

When i try to migrate mailbox to a different database, i always get this error as soon as the migration process starts


Error: MigrationTransientException: Couldn‎'t find a move request that corresponds to the specified identity ‎'45665703-3f50-430b-9803-cd177ff87a57‎'. --> Couldn‎'t find a move request that corresponds to the specified identity ‎'45665703-3f50-430b-9803-cd177ff87a57‎'.

 

In the end, the status of the migration is "Completed with errors" and the mailbox considered as failed. However, that mailbox is successfully moved to the target database if I check it with EMS.

 

If I set up the migration with option "Manual complete the batch", I still get this error at the beginning of migration but the status of migration will be "Completed" with no errors at all.

 

Why is this happening? Do you have any solutions for this issue? Thanks in advance.

Could you please run the command

Get-migrationuser -identity mailbox@domain.ext | Get-MigrationUserStatistics | FL

Before completing the request?
This should give you more details on why the move request was completed with errors.
I have exactly the same issue during expansion and migration of our Exchange 2016 cluster.
Today i logged a ticket with Microsoft support. I'll hope to get a reply soon.
I did use the command below, but it says {} after skipped items.

Get-migrationuser -identity mailbox@domain.ext | Get-MigrationUserStatistics | FL

I am a little less concerend now. What i did was:

  1. Removed the pending “move request” for a user with this error.
  2. Re-created a new migration for the same user.
  3. Guess what? The output is exactly the same, that means that there really are no items skipped for real.
