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?
First and Last name
Also go to Mailbox Delegation and make sure that User2 doesn't have Send As and Full rights to admin mailbox
Afer this changes double check User2 outlook settings and download again Global Address List to his outlook.
