Thank you LukasSMSFT for your quick reply.
I am running on Windows server 2016 by the way.
Can you just confirm one more thing for me please as I think the guides and exchangeupdatewizard does not take in to consideration Hybrid setup and I find that very strange. There must be a bundle of people out there running Hybrid mode.
The "thing" then, I usually run these two commands when upgrading a CU:
setup.exe /PrepareAD /TenantOrganizationconfig:C:\scripts\0365oconfig.xml /IAcceptExchangeServerLicenseTerms
setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms
And then I do a Azure AD Refresh from Azure AD connect
Can you confirm that all these steps are still required going from CU21 to CU22 or can any of them be skipped.
Really appreciate your help.
