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. firstname.lastname@example.org 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?
