432 4.3.2 STOREDRV.Storage; mailbox server mapi session limit exceeded; STOREDRV.Deliver.Exception:TooManyObjectsOpenedException.MapiExceptionSessionLimit;Failed

    Question

  • Wondering if anyone can point me in the correct direction for dealing with a really annoying issue. The last few weeks we have had mail flowing really well and now the following issue has popped up yet again. I have no idea why after everything has been working well. No changes have been implemented anywhere so I'm stumped as to why this has started happening.

    The problem is on some of the queues with the following message:

    432 4.3.2 STOREDRV.Storage; mailbox server mapi session limit exceeded; STOREDRV.Deliver.Exception:TooManyObjectsOpenedException.MapiExceptionSessionLimit;Failed

    Google has not been my friend when looking at this and what happens is that the relevant queues this hits builds and builds and then it re-tries, deals with a shit load of mail and then it starts to build again.

  • Running CU5 - no plans at the moment to install the latest unless we really really have to.

  • Hello

    You should REALLY consider updating your Exchange.
    Seriously.

    You run a quite old version (around half 2014).

    This is quite unsafe.
    You will prevent many problems keeping your Exchange servers up to date.

    Really.

  • I'd update to CU10 and see if it fixes your problem.

  • Hi,

    On this issue, firstly, have you ever tried to restart the problematic mailbox server for test?

    Then, please check Event Viewer if it identify this problem firstly. Generally speaking, when this problem occurs, there would be Event ID:9646 generated in Event log. If that it is, post the detailed message here.

    Besides Event 9646, please also check if there is any other Exchange server performance log, such as Event 15004.

    Generally speaking, you can fix this problem by increase the limitation value:

    1. Start Registry Editor (regedit).
    2. Navigate to the following registry subkey:
        \HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
    3. Right-click ParametersSystem, point to New, and then click Key. A new key is created in the console tree.
    4. Rename the key MaxObjsPerMapiSession, and then press Enter.
    5. Right-click MaxObjsPerMapiSession, point to New, and then click DWORD (32-bit) Value.
    6. Rename the key to objtStream. Press Enter.
    7. Right-click the newly created key, and then click Modify.
    8. In the Value data box, type the number of objects that you want to limit this entry to, and then click OK.
    9. Restart the Microsoft Exchange Information Store service.

  • Hi, thanks for the reply - I know it's a bit behind but to be honest I really don't want to do this. There are over 7 servers globally on our network and even thinking about this just brings me out in a cold sweat. And to be honest I would really like to figure out why this has started happening. Updating to the latest version will probably fix it but it will also bring about a whole new load of problems I simply cannot afford and deal with and I won't learn why it started occurring.

  • Hi, thanks for the reply. Your advice I have read before when I first googled this so I checked for the 9646 events however I did not locate any. I did not check for any 15004 events though as this was not mentioned - I will do this on my return to the office on Monday. I'll let you know. 
    Saturday, February 20, 2016 4:57 PM
  • Hi, there are no 9646 or 15004 Events. Today ( in fact right now ) the problem has yet again appeared. The following below are examples of E-mails in the queue that record the problem. I cannot find any explanation as to why this is occurring and why it has suddenly started occurring.
