Error: Cannot query rows in a table
This is a transient issue that has no sure fix.
This error can occur in rare cases, specifically when migrating to Exchange 2016. This has been identified as a Microsoft Exchange 2016 bug. Microsoft has resolved it, and it is available under the CU4 patch, which can be found here.
This error can also occur when there are insufficient permissions. In this case, verify that customer permissions are correct, and perform the migration again.
