I've recently migrated from a SBS 2003 server hosting remote user's mail via POP3/SMTP to a SBS 2008 server using RPC over HTTPS (Outlook Anywhere) for clients to get mail. All clients are running Outlook 2007. For some reason, of my 25 or so users, approximately 5 at a time are unable to connect to the server. It's never the same 5 users, it seems like it's just the last 5 to try to connect each time. The only way I've found to get these users connected is to do an iisreset to restart services. There are no related events in the event log that I've been able to find and the only error code I've found when enabling logging in the Outlook client is 0x80040115, which may or may not be related (I couldn't find anything online related to this issue). Thanks in advance for any help you can give.
