We have an issue with a new user taking over an email address.
User1 needs to have email@example.com and user2 needs to have firstname.lastname@example.org
Under User1 in exchange console they have email@example.com and firstname.lastname@example.org
Under User2 in exchange console they have email@example.com and firstname.lastname@example.org
However, when internal emails are sent to admin@ they come up with User2's name in Outlook.
User2 used to have the address but it has been changed across this week.
From what I can see everything under Exchange looks fine. I have removed the effected address from AutoComplete on the client machine, restarted the Exchange Services and finally rebooted the server.
The Global address list still shows User2 to have email@example.com
Is there any where else other than where mentioned that the address list would pick up the domain.local from?
