Hi all,currently, we are migrating our 2007 Environment to 2013
Following scenario.
User A is manager of a distribution group "Group A"
All members of this group, including him, have their mailboxes on 2007. "Group A" is not upgraded. User A is able to manage this group.
User A is now migrated to 2013. Now he is unable to manage Group A anymore, OWA error says the object should be version 14.0.xxx
I assume, I can fix that error by upgrading this distribution group (by using -forceupgrade)
But my question is:
Is there a way to "downgrade" the group via Powershell, if something goes wrong, or only a way to go back will be to recreate the group in 2007 Environment?
