I've changed the default email address from firstname.lastname@example.org to email@example.com, applied the changes and closed the user profile. I've then logged out and back into Outlook on my workstation and sent a test email to my account. The email appears to come from firstname.lastname@example.org which is correct and how I want it to appear.
However, if I go back into the user profile on my server, it's changed back to email@example.com by itself. The only thing I can think of is that mailbox alias which is set to "dave". Does this need to change too? I haven't done so incase it gives me a new mailbox or something.
Can anyone help? Thanks in advance.
