My problems are with Outlook XP/2003.
Frequently when starting up outlook, I will get a connection error. I simply do a File>Connect and the problem is solved. This is with SME6.0 with all updates applied along with an SME6.0.1 servers.
The other issue I have are with folders that contain both email and folders. Using Outlook, I can't see the root folder contents, but I can see contents of folders below it. This doesn't happen on all folders. I can usually resolve it by using IMP and renaming the root folder.
MJB, what problems do you see?
