Had a customer who wanted to update an Outlook contact who is part of a group email address. When we deleted the user in the group the group was gone.
We looked at was to recover. The big suggestion was to recover deleted items. We went into deleted items but the group wasn’t there. They are running an internal Exchange 2012. We looked at there OWA to try to recover.
The following article helps me solve this. It was the least technical link, but solved my issue.
The big issue is when you delete a group it goes into the deleted items with the date the group was started and not the date the group was deleted. I went back into the deleted items and at the bottom there was a link to see more and the item I was looking for was at the bottom.
I hope this helps someone else out there…
