I have a SBS2003-Standard R2 , ES is patched to SP2, this morning I try to add a external user to collect mail via POP3, POP3 service is running, also restarted + restarted Info Store, the user can get as far as authenticating then error on incorrect username/password.
I have checked most settings, tried using SSL, ports 995/110/25 all opened , theres already a server genarated cert, so I thought may be POP3 also needed one, so I assigned teh same cert to the POP3, again no luck.
Few years ago I recalled doing the same thing with another company using SBS2003, the process were so straight forward that I didnt even bother to take notes.
Where have I gone wrong on this ?
The users are logging in as domain\username then password
The server POP3 is mail.domainname.co.uk
