  • We are also seeing this issue, and reboots/recycles have no affect.  We are also seeing random ActiveSync problems.

    I cannot believe how incredibly buggy 2013 is.  I knew it was going to be bad, but I couldn't imagine it would be this bad.

  • Same issue here, after every reboot.
    Went to C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Sync and renamed the web.config file to old.
    - Renamed web.config.bak to web.config
    - Performed IISRESET
    - Now the events were not coming up.

  • We are seeing the same issue in Exchange 2013 SP1 and Windows Server 2012 R2.

    "The setting SupportedIPMTypes in the Web.Config file was missing.  Using default value of System.Collections.Generic.List`1[System.String]."

    What should we do here? I like to keep my event log clean and i've tried the suggested IISRESET/bouncing the server but it does not help.

    This is a fresh EXCH2013SP1/WIN2K12R2 install.. how do these bugs slip through into a RTM'ed product when they present themselves right at the begging?!

  • How it slips through is MS has all of their senior resources dedicated to Office 365.  On premise Exchange is an afterthought at best.  There's a host of false positive error messages in CU5, that have existed since RTM.  SOme cause issues, some don't, but they all clog up the event viewer with garbage.

  • I did not have this error when I installed the server starting at SP1.  I have since installed CU7 and this error started at every reboot.

  • Same here! We have a fresh LAB-Installation and also same behavior in productive Environment. It happens just the same in both Installations! This is after CU7!

    Also we get Event-ID 1309, ASP.NET 4.0.30319.0

  • I'm noticing the "DeviceIdMissingOrInvalid" errors as well. Did you ever resolve the issue?

  • Same for me, but on Windows 2012 R2 with Exchange 2016 CU1.
    Friday, May 20, 2016 1:24 PM
  • same issues.  Windows 2012 with Exchange 2013.

  • By the way, same issue on Exchange 2016 CU2. We started to migrate from Exchange 2010 to 2016. We also see some random ActiveSync issues (mostly disconnects) on Exchange 2016. Over night they got solved without any action from the admin side. So every morning ActiveSync started to work for the users. A little bit frustrating ...


    Found the following document which said:

    "On the General tab, under Application settings, configure the setting specified in the event description to the default value."

    Did anybody tried that?

  • @BastianWebster

    Can you make a new thread at Exchange 2016. This is very old.

  • @PK Sarangi

    I could yes, but why? To have another thread with "hey we have the same error?". I leaved a response here  as most companies will migrate to 2013 instead of 2016 (as its to new for most of them) and will run into the same issues. Additional: As the error exists in 2016 as well, I didn´t expect anybody would response to the new thread (which you asked to create) with something else as "me to and it hasn´t fixed since 2013"...

    P.S. Please do not reply as this would be offtopic thanks ;-)
