I have an sbs2003 server sp1 exchange sp2. I have been able to configure and connect several different handsets to this server and they all have the same issue they can send a mail, look up the GAL but they cannot download email to the phone. I have a second sbs server 2003 and tried all of the handsets including an iphone and they all work perfectly.
Things I have done
Added a third party certificate to the server
Checked the working server config with the non-working one (they are the same)
Deliberately broke authentication etc with predictable results
As it is sbs2003 the usual re run internet config wizard to set up directories/web server again
The iis logs show 401 1 and 401 2 errors but I get these on the working server and I have seen them on several other servers but they all work so I think this is a bit of a red herring
At this point I am close to having to re-install the system (but would prefer not to)
Any light you folks can shed would be appreciated.
