One of our public folders on O365 contains a number of calendar items for bookable resources. One of those calendars has been deleted and I need to restore it if possible, hopefully with any future appointments. I have gone through a restore process for the calendar via PowerShell ( Get-PublicFolder –Identity "NON_IPM_SUBTREE" –Recurse | SELECT Identity) and, whilst that completed ok, the missing item has not returned so I assume that the restore process needs to be run on the containing folder.
Is it possible to confirm if running the process on the containing folder will keep appointments in existing calendars as I don't want to make things worse by resetting/overwriting those?
