Really weird thing going on with a clients 2011 SBS server. I set up a new user recently and called the username Phil Scarsbook, a mailbox was created and all was well until I was told that the guys name was actually Phil Scarsbrook. So I went into ADUC and changed the username to the correct spelling. I made sure that the smtp email address was changed to the correct spelling and checked in EMC that the mailbox had the right spelling. When the user sends an email it arrives from the correctly spelt email address however if you send an email in to the user you get a bounce back saying no such mailbox exists. I'm assuming it's a problem caused by renaming the user but I;ve run out of places to check that the spelling of the user is correct.
Would appreciate any thoughts on what may be causing this.
