Hi,

What's the detailed version of your Exchange 2016 and 2019? Please check with the following command:

Get-ExchangeServer | Format-List Name,Edition,AdminDisplayVersion 

Here are some suggestions for you:

1. Use the command to check the database status. Make sure the database is mounted and the index state is healthy:

Get-MailboxDatabaseCopyStatus | fl name,status,contentindexstate 

2. Make sure the mailbox you want to move works well, and it is not quarantined.

3. Try to move to other databases on Exchange 2019, and move other mailboxes to see if the issue only occurs with specific database or mailbox.

4. Check the move request with more details:

Get-MoveRequestStatistics -Identity <MoveRequestIdParameter>
Get-MoveRequestStatistics -Identity <MoveRequestIdParameter> -IncludeReport| FL report
