    What is your detailed exchange version?
    Please take the following steps to recycle the MSExchangserviceapppool:
    Click Start, click Control Panel, and then click Administrative Tools.

  • Exchange 2016
    Version 15.1 (Build 396.30)

    I've recycled the application pool. I will update if it shows up again.

  • Hi,

    Do you still receive the evevt id 5011?

    According to the following link,event id 7036 is a normal condition and no further action is required.

  • Hi,

    Do you have high CPU usage in exchange server?

    I suggest you refer to the following link to diagnose the issue:

    https://support.microsoft.com/en-us/kb/919792

    Also try to check out the IIS logs,normally the path are at C:\inetpub\logs\LogFiles\W3SVC1

  • Not any real high use on it, also i just built a new 2016 exchange server and notice it is also having the exact same issue...

    When I go to the logs I see a lot of them in there, how/what should I be searching for in them to help me on my way?

  • I'm having the same issues, with each exchange app pool periodically restarting with the same error; this causes disconnects to Outlook clients whenever an RPC app pool crashes. There is no consistency, it will be any random app pool at any given time. Sometimes several at once.

    I tried using the debug diag tool on IIS, without much luck. The reports showed that errors were occurring but didn't offer any more insight. 

    I am however running Exchange 2013 15.0 (Build 1236.3), these errors are being generated on the CAS with no errors on any of our DAGs.

    I have tried: https://blogs.technet.microsoft.com/jamec/2014/01/29/exchange-2013-the-case-of-the-mysterious-crashing-rpc-proxy-application-pool/ (comic sans, because that's just how M$ roll) and it has not made a difference.
