Moving mailbox to another Exchange server 2016 member gives error

Running command

New-MoveRequest -Identity 'username' -TargetDatbase "DB01"

gives

Couldn't switch the mailbox into Sync Source mode.
This could be because of one of the following reasons:
  Another administrator is currently moving the mailbox.
  The mailbox is locked.
  The Microsoft Exchange Mailbox Replication service (MRS) doesn't have the correct permissions.
  Network errors are preventing MRS from cleanly closing its session with the Mailbox server. If this is the case, MRS may continue to encounter this error for up to 2 hours - this duration is controlled by
the TCP KeepAlive settings on the Mailbox server.
Wait for the mailbox to be released before attempting to move this mailbox again.

    Hi @azhar Nasim,

    • Have you checked the above reasons for the failure of the move？If not, please check if any move request is running for the mailbox using the following command.
    Get-MoveRequest -Identity ‘user@contoso.com’ | Get-MoveRequestStatistics –IncludeReport | fl
    • Please try restarting MRS on the server. Make sure it is running well and set to log in as an account with "Mailbox Move and Migrate Permissions". You can move the mailbox again after restarting.
    • Check whether other mailboxes can be moved normally, if the problem only exists in the current mailbox, we suggest you export the mailbox data to a pst file and try to fix the mailbox or create a new one to enable it.

    Run Mailbox Repair Request:

    New-MailboxRepairRequest -Mailbox <user name> -CorruptionType ProvisionedFolder,SearchFolder,AggregateCounts,Folderview
