Calendar Sharing in an Exchange On-line Hybrid Setup

In an Hybrid configuration, while migration of Resource or Room Calendars to Exchange On-line works there are a few configurations that will need to be set with the help of Power Shell.

Recently I performed such a migration and found that while the Calendars were available to both Office 365 and on-premises users, there were a lot of issues with; Bookings, viewing details and notifications. In order to sort this out I had to run a few Power Shell commands against each affected Calendar.

Info on this command can be found here : set-mailboxcalendarfolder

Sets whether the calendar is published to external users

Set-MailboxCalendarFolder\Calendar -PublishEnabled $true

Sets the detail level users can view

Set-MailboxCalendarFolder -Identity “\Calendar” -DetailLevel FullDetails

Info on this command can be found here: set-calendarprocessing

Set this to correct an issue where users do not receive a confirmation on a successful booking. More info

Set-CalendarProcessing -Identity “” -ProcessExternalMeetingMessages $True

Hope this helps!
