Hi,
I have experienced the same behavior on this CU and also on CU11 for Exchange2019, that after installation of the CU, IIS cert on port 443 is reset to original Microsoft Exchange, and i have to manually replace it with the one we use (signed by external provider). Otherwise I see cert errors in Outlook.
Also I'm seeing strange behavior on Edge Servers, we have 3 of them, i recreated the subscription files, and resubbed them on MBX servers which went fine. However if i try to create another subscription file I'm getting error that LDAP server is unavailable. And on MBX servers i see this error when i run test-edgesync :
EdgeSync service cannot connect to this subscription because of error "The supplied
credential is invalid.".
However if i reboot the edge and recreate subscription file and then sub the EDGE on MBX with this new file, everything works fine.
Anyone seeing similar issue ?
Thanks
