Failed to reset target mailbox

Question

Hello, moving mailboxes to a 2010 server to another one in a different forest, for some mailboxes gives " completed with warning" with log below. Some mailboxes move complete with success. Need a clean-mailboxdatabase to be able to access
the mailboxes with warning. What could be the cause ? Thanks

Hi,
Based on the description, the mailboxes moved successfully with warning seems normal, is it right?
What's your Exchange version?
I searched and found that the issue you experienced with moving mailbox is a known issue in Exchange 2010 SP2 RU3. I recommend you install the latest rollups.
If your Exchange version is Exchange 2010 SP3 or later, please check if there is any issue about AD replication. By default, moving mailbox in the same site, the homeMDB attribute change will be replicated to all DCs immediately. But the inter-site is 15
minutes.
If the issue persists, please check if there is any related events in the application log.
Best regards,
Belinda
