I am getting this warning over an over again

Log Name:      Application
Source:        MSExchange ActiveSync
Date:          12/20/2019 2:36:09 PM
Event ID:      1033
Task Category: Configuration
Level:         Warning
Keywords:      Classic
User:          N/A
The setting SupportedIPMTypes in the Web.Config file was missing.  Using default value of System.Collections.Generic.List`1[System.String].
Event Xml:
<Event xmlns="">
    <Provider Name="MSExchange ActiveSync" />
    <EventID Qualifiers="32772">1033</EventID>
    <TimeCreated SystemTime="2019-12-20T19:36:09.696918100Z" />
    <Security />

I tried adding this to the web.config file

    <add key="SupportedIPMTypes" value=""></add>
    <add key="LiveIdBasicAuthModule.ApplicationName" value=""></add>
    <add key="UserWorkloadManager.PermitSynchronousTaskExecution" value="false" />
    <!-- Config file for tracing -->

Based on my test, issue could be reproduced by either restarting the MSExchangeSyncAppPool application pool or rebooting the server. Same issue in Exchange 2016 CU12.

I am currently at CU10   I have CU12 available to install

But what I found so far is it is the same on CU12  

Any Ideas or thoughts?

Thank you


PS I am already Ignoring the pesty Event Id 3028 event killbits which that's all the answer I got on that one is to ignore it.
