Hybrid - Calendar cross permissions
Hi, i'm deploying exchange hybrid and after migrating some users to Exchange Online, on-premise users have been asked for credentials to open Office 365 calendar users.
I verified organization ...
That's usually due to missing Outlook updates/older version. Or if the calendar was added previously to the profile, you can try deleting/re-adding it.
Thanks for reply. We have the latest version of Outlook. Calendar was present in Outlook profile before the migration. It runs when i enter credentials but i can't imagine having to enter password each time i migrate a user (exemple: if a user have 100 calendars open in its profile).
