  • Exchange Problems in SBS

    Hi there

    I have a SBS 2008 box that I am running Exchange on with 10 users.

    Every now and then (random time but normally around a month or so) we stop being able to receive mail from external addresses. Internal works fine.

    We have to restart the server and then it will be ok again.

    I have checked the space on the disks that Exchange stores are on and there is plenty of space so I dont think it is that.

    Anyone have any ideas of where to start looking??

    what do your event logs say?

    How much space is on the C: Drive ? (not the drive the Stores are on)

    Exchange also monitors disk space on the drive that has the Transport queues. With sbs08, by default, this is usually the C: Drive.
    If this falls below a certain level (called the Backpressure Threshold) then it will stop accepting inbound email. (Internal email will still work.)
    If it falls further, it will stop accepting internal email as well.

    Take a look through your evts for 15002, 15004, 15005 (or other events in that range)

      Hi there

      Sorry for the delay in replying.

      Have checked the event logs and there doesnt seem to be anything with those event numbers you refer to.

      There is 7.6Gb left on C.

      It has just dropped out again on us. I decided to go through eaxch of the Exchange services that are started and stop and restart them in order to try and narrow down the problem.

      After restarting them there was still no external email coming in to the clients Outlook.

      A server restart then sorted the problem.

      Any more ideas??? Im at a loss

        By the way the version of Exchange 2007 is 8.1 so I assume that I could install service pack 2 and 3???

        We are using SBS 2008

        Cheers

          It sounds like Exchange 2007 back pressure is in effect.

          I would install the SBS BPA and run that to make sure you server is setup properly and that you have all the necessary patches. If you still have issues with incoming email then look at adjusting the back pressure settings or turning them off.

            dependent on the size of your volumes.... 7.8gb .....shouldn't.... trigger backpressure... it may though.

            I would definitely recommend installing the service packs. Make sure to do this out of hours, and remember that an Exchange service pack is similar to almost a complete reinstall (I beleive I've seen someone say that before ?)

              Hard drive space is by no means the only trigger for back pressure. I've found that memory consumption is the one that I most encounter.

                true.. true..
                I've never seen memory actually.

                I've seen plenty of disk do it. (script to delete IIS logs, solves that, thanks)
                teh oter one I'e seen occasionally is buckets.
                best I can understand.. there's just a whole bunch of email to process suddenly..
