Configuration to auto switch mailboxes is not saved after committing changes
There is a known issue with MIgration Manager 8.7 where if the source is Exchange 2000, an auto switch collection cannot be configured and saved. When returning to the workflow settings of the switch collection, the settings have been cleared.
There is a workaround for this issue, but it involves editing your SQL database. We do not suggest manually editing the SQL database unless absolutely necessary.
PLEASE FIRST BACKUP YOU SQL DATABASE
-Open the table "Collections" in SQL database,
-then right click the server pair, and select "Reapply Agent Configuration"
