So, I would greatly appreciate if anyone could help me find out what new email address has been added to list mailboxes due to an email address policy.
We had a default policy that was applied to most mailboxes and we created a "Test" Email Address policy with Primary SMTP address which mistakenly was applied to everyone(Due to its priority being higher). We have since deleted the policy but now every mailbox now has this added smtp address.
Is there a way for me to see what mailboxes didn't have this newly added smtp address before?
Thanks
