Hi, latest Security Update for exchange KB5044062 - broke "MAIL FLOW" rules.
Exchange on Prem. win. server 2019 / exchange 2019 - all worked Ok before update, after tuesday update - MAIL FLOW stopped working. enabling/disabling rules - temporally makes everything work again. after some time (couple of hours) it stops again. any suggestions? (except for uninstall update)
Same here, I Unstall the updates to solve the problem, waiting for another patch from Microsoft.
Same Scenario for me,also either I restart transport service or the server itself.
Other's have noticed this problem too. Me also.
Restarting the Exchange Transport service makes it work for a while, then it stops again. So, I decided to make a scheduled task to simply restart the transport service that runs every 30mins. That seems to mitigate the issue and keep the rules working without requiring repeated manual actions. Perhaps that will work for you, until this can be corrected.
I did so ," a scheduled task restarts the transport rule service each 30 mins", waiting for the new release
the batch runs in a scheduled task /script code is:
@echo off
echo Restarting MSExchangeTransport service...
net stop MSExchangeTransport >> C:\Temp\service_restart_log.txt 2>&1
timeout /t 10 /nobreak >nul
net start MSExchangeTransport >> C:\Temp\service_restart_log.txt 2>&1
echo MSExchangeTransport service restarted. >> C:\Temp\service_restart_log.txtHello Nino,
We have noticed other strange issue after installing the November patch.
Our ECP is not working good anymore. After login we see a garbled portal. I tried to copy the original webconfig to the ECP directory but that did not help, also removing the patch does not solve this. Before installing the patch ECP worked just fine.
We are on Windows 2016, Exchange 2016 latest CU.
We had this behaviour also on 2019, with 2022OS with one server in one environment. We rebooted the server, disabled all AV and re-ran the patch and after that ECP looked fine. This should be default behavior if you fun into an issue. Think something went wrong with updating some files. Install state in the log was succesful.
The portal looked like a 1992 web site. No markup, just txt and non responsive links.
