Hi,
I have come across and issue with Exchange Hybrid where the Outlook client prompts for credentials after migration. The fix detailed in the article below resolves the issue.
However, a lot of the Outlook clients seem to be missing the HKCU\Software\Microsoft\Exchange key all together and I cannot work out why some have it and others do not. There is nothing on the internet explaining why this issue occurs. Has anyone come across this before?
Thanks,
Mike.
