Hello all,

 

I'm Vincent and I'm Exchange administrator in my International Research Organization.

Our Exchange farm is composed of 4 Exchange Server 2016 Enterprise CU 22.

I recently noticed a lot of events with ID 4999 in the Application logs on all 4 servers like below:

Log Name: Application

Date: 25/02/2022 15:09:28

However, none of our users using ActiveSync with their mobile complained so far. 

Did one of you already had similar problem?

Same ErrorID 4999 here, only with another processID (mostly 25636, but also others):

Watson report about to be sent for process id: 25636, with parameters: E12, c-RTL-AMD64, 15.01.2308.021, w3wp#MSExchangeSyncAppPool, MSExchange ActiveSync, Microsoft.Exchange.AirSync.Common.SchemaConverter.Entity.EntityContentProperty.get_MIMEData, UnexpectedCondition:NotImplementedException, 0, 15.01.2308.021.

Everything started on 13.2.2022 with EventID 4999 but other message within:

Over 160 views in this thread but no solution or at least a hint?

I have exactly the same issue. Would be nice somebody will pick this topic up :\

Hi @TobiasSchrade  and @BalticNative  ,

Which version of Exchange do you have?
On my side I verified all monitoring probes on all of my servers as explained here: https://docs.microsoft.com/en-us/exchange/management/health/troubleshooting-activesync-health-set
None of them report any error. ActiveSync is working properly and no user complained.
I think that we will have to live with it ...

I'm seeing the same exact errors with Exchange 2016 CU22.  I recently upgraded to CU22 with the naive optimism that it would be resolved with that CU but no dice.  Has anyone else found a fix for these errors?  I'm not getting any complaints but if that AppPool is indeed crashing and restarting repeatedly through the day I can't imagine that's a good thing.
