MDaemon Connector Outlook 2003 - error logging clients onto server

Hi All
MDaemon is running on a Win2k3 box to provide a communal e-mail service for Reception staff in a small hotel. There is noe Exchange present. There are four XP Pro PCs running Outlook 2003 that use the MDaemon Outlook Connector to retrieve messages from the server.  The key thing to note is that all four Outlook clients are configured with the same email account e.g. reception@smallhoteldomain.co.uk and can all see the same inbox and folder structure.  This setup has been running well for some three years until last week when two of the PCs could not read or reply to any e-mail.

The Outlook client on both these PCs went into cpu loop (using 95% constantly) and network flood when trying to connect to the MDaemon server. As soon as Outlook was closed down the PC was fine.  The next day one of the PCs that experienced this problem connected OK and caused a third PC to demonstrate the same error when trying to connect.  

I updated the MDaemon server to 2.2.5, to match the clients PCs, but this made no difference. In my limited experience of this program, I would guess there is suddenly a session issue casuing this.

Can anyone give me a clue as to what to look for?

Thanks, C

What colour is the Mdaemon icon in the System Tray?

Has the location of the mailboxes changed recently (mind you, that would affect all access to the mailbox, not just to one or two pcs)?

Separating out the elements here, let's deal with the Mdaemon one first - this is the program that handles emails, if that doesn't work then Outlook Connector probably wouldn't either.  It sounds to me that Outlook is setup to use IMAP.  Have a look at the IMAP tab, are you seeing evidence of attempted logins there?  

If you're not seeing activity there, check firewall is not blocking port 143 (for IMAP).

What anti-virus product is being used?  Do you still have the problem with it temporarily switched off?

Thanks - I'll check on site on Monday and get back to you.  
The AV is AVG Internet Security Business edition, but I need to check if the firewall element was installed and active.

Check also what the IMAP and SMTP server settings are set to in Outlook.  If this is an internal network I would be inclined to use the IP address of the Mdaemon server rather than a domain name of any sort.  If a domain name is being used then what is setup in the DNS server for that pc?  Does it point direct to the correct place, or is there an abnormality in the DNS "hierarchy" somewhere?

The firewall is not blocking port 143 on the server.  I can see all 4 PCs logging into IMAP sessions on the MDaemon interface.

IMAP and SMTP settings in the Outlook on all PCs are set to the server IP and domain name not being used.

Disabling the AVG makes no difference.  Two of the PCs still have high cpu usage when Outlook running.  Also these machines can see all the folders, Inbox etc and can preview mails, but cannot open the mail in Outlook or reply.

uninstalled AVG and Connector worked OK.  Re-installed AVG IS 2011with custom settings excluding the Outlook plugins and works OK again.

thanks, C
