Hello,

We have a plan to migrate mailbox from one forest to another using MS native migration tools - New-MoveRequest or the New-MigrationBatch.

Migration method used as per the instruction below.

https://learn.microsoft.com/en-us/exchange/architecture/mailbox-servers/prep-mailboxes-for-cross-forest-moves?view=exchserver-2019

My question is how can we rollback\offboard the mailbox migration, i.e if needed how do we move the mailbox back to source forest? I don't see any MS article detailing this, any help in this is really appreciated !

    Hi @Acloudguy

    To me It may depend on which migration process you are in when you want to reverse the change.

    For example, if you have finished the migration to another forest, you can simply re-do the migration to move the user and the mailbox back to the original forest.
