Hi Risingflight,

Thank you for your question.

Error1:

We could run the following command: Get-MoveRequest TargetDatabase <databasename> | FL ExchangeGuid

Then it will return like:

ExchangeGuid   : 0c4a031c-2ff5-4b4f-920a-ceeb811be877

ExchangeGuid   : 0c4a031c-2f55-4b4f-920a-ceeb812be877

Then we could remove it by the following command to check if the issue persist:

Remove-Moverequest 0c4a031c-2ff5-4b4f-920a-ceeb811be877

Remove-Moverequest 0c4a031c-2f55-4b4f-920a-ceeb812be877

Error2:

Did you get error which is MapiExceptionADPropertyError : Unable to make connection to the server when you run the command new-moverequest -identity 'user@mydomain.com' -TargetDatabase "Ex2013DB"

Or else?

We could make sure the target database which was mounted.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,
