  • Outlook Losing Connection With Exchange

    Hi,

    We have recently started having strange issues where every users Outlook (2003) suddenly loses its connection with Our Exchange (2003) server. Cant figure out why. When this happens I can still fully access and ping the mail server. webmail works fine during this as well. I dont see anything peculiar in the event logs. Any ideas why we would just drop off like this? It seems to eventually fix itself after a few minutes or so.

    Any ideas?

    Thanks

      Thanks for the response.

      The only recent change was the installation of Symantic Endpoint protection. I disabled it on the Exchange server before leaving last night to see if that has any bearing on it. Its really odd, because when it goes down I have full access to Active Directory, I can remote into the Exchange server, but Outlook just locks up if you have it open, or it just hangs if you try to open it. The little Outlook icon in the bottom right corner tray gets covered with an exclamation point and says something along the lines of Outlook has lost its connection to the server.

      I'm curious to see if disabling Endpoint has any affect.

      Thanks

        if it locks up ping it with the FQDN and make sure it will ping.

        How does the event log look like, may want to turn on diagnostic logging on to further test what is going on.

        Is cached Mode on?

          The latest products from Symantec do not seem to be getting good reviews from users.

          However ensure that you have the latest network card drivers in the server. That has caused some problems in the past.

            So far so good today. I have to say I am not thrilled at all with Symantecs new endpoint product. I already had to remove it from our Great Plains server, as it prevented that application from running on the server. Between that and its enormous footprint its really becoming more of a headache than its worth.

            Thanks for the suggestions, and I'll keep you posted

              When I was consulting we had endpoint on a few servers and it jacked one of them up, had to uninstall and go back to what works.

              Now I use EPO and Groupshield.
