I have a very interesting scenario. Running Exchange on SBS2003.
I'm using SMTP and outlook as my client side. THe company uses general names as it has quite a large staff turnaround. I was tasked to create a new user that was 'upgraded' from one of the general users to his own personlised profile. The general user name is 'SEARCH', which was assigned to a new employee. I renamed the 'searc' profile to the usersname 'craig' and created a new user called search. THis way I would not loose any documents, mail settings etc. and it made it easier to keep the existing user. I then added another SMTP email address for the user, email@example.com, as I have done with the other users as well - aliases. For some odd reason I cannot email to this new address. I get the follwoing error:
firstname.lastname@example.org: host mydomain.com[***.***.***.***] said: 554
<email@example.com>: Recipient address rejected: Please do not reply to
this address (in reply to RCPT TO command)
I have deleted and recreated the address, but no luck. I also tried to create another new user called craig and by default the address was firstname.lastname@example.org, just to test and see, but this also did not work.
I'm at a dead end here, please let me know if someone else has experienced this.
