SBS2008 IMAP intermittent - Thunderbird - The connection was refused
SBS2008 Server
20 x client on LAN with Thunderbird (lets not discuss this choice) connecting to the Exchange server via IMAP (STARTTLS)
One of the workstations has a issue were several times a day thunderbird report 'The connection was refused'. Restarting the workstation sometimes solves this.
The event logs on the workstation do not show anything related.
The event logs on the server do not show anything related.
Any ideas?
I don't have much experience with IMAP on Exchange - Maybe there is some tweak to make it work 'correct' ?
Thanks

1 out of 20 having the issue,right? Do you try to create for this user to user IMAP on other machine?
Most problems with IMAP on Exchange are outside of Exchange. They are usually client related.
Have you got logging enabled on the IMAP server? It isn't enabled by default. That may give you some more information.
Not really much you can do with IMAP configuration wise, it either works or it doesn't in my experience.

Ok, let add some more details. This is new client to me with a setup they have self-managed for a some years, some bits are ok, some setup is ugly.
5 machines were having this issue last week and it seems to be related to an AVG update that requested the machines to reboot. After the reboot these machines had an issue. A further two of three reboots seemed to clear the issue. Since then, AVG has been removed and a bitdefender powered AV has been installed (something I can support).
So 4 machines cured, but this 1 machine still has issues. AVG removed, still issues.
As a work around I have found a license for Office 2003 in there collection of discs anf have installed Outlook 2003. This worked first time, but not perfect as old mail and contacts still in Thunderbird.

Let me also add, that one a second workstation is now reporting 'connection refused' when using with Thunderbird/IMAP/STARTTLS
Can you advise how to switch on IMAP logging on the server?

EMS commands.
This is the TechNet article that explains how.
http://technet.microsoft.com/en-gb/library/aa997690(v=exchg.150).aspx
It is for Exchange 2010, but the commands are the same for 2007.
Be wary of the paths involved, as the logs could get quite large if you are using IMAP a lot.
Mail and Contacts should be in the mailbox, so seen by Outlook 2003. Check the mailbox through OWA to ensure the content is there. If it isn't, then the old client is removing the content, which rather defeats the point of using IMAP.

Good find - thanks
I assume the IMAP service will need restarting?
