[ms office - o365] O365 - Calendar Sharing Permissions - Inside my Organisation

[jamwatn]

Hello,

 

Microsoft was unable to help me with this understandably because it is a difficult one, but it is their product!!

 

A user has found out that their calendar was set to 'Can view all details' in Sharing and Permissions in O365 but they would like to know when and who changed this.

Also, I would like to audit every calendar to see what is set for the entire organisation.

 

 

Does anyone have any ideas on an answer for this?

 

Thanks

I've use this script before to get a calendar permissions report.
