Hello Satheshwaran, Thank you for a good article. I was wondering if it will be possible to restrict calendar permissions for a certain user. lets say Hank. So, if “default” has Editor rights it will count for all users, including Hank. But I want hank to have free/busy only. I can set the perisssion and Hank is listed as free/busy, but “defaults” permission overrules and gives Hank Editor rights. Is there a way to set a deny permission for Hank?
Hi Satheshwaran,
You helped me a great deal with this. I still have a prolem with Calendar rights. Default rights are assigned to LimitedDetails. However some users already had AvailabilityOnly or LimitedDetails assigned to some mailboxes. How do I remove all AvailabilityOnly/LimitedDetails rights for those users on these mailboxes?
Thanks in advanse,
Victor
Hi Satheshwaran,
I am trying to figure out a way of using the Get-MailboxFolderPermission command to get all mailbox calendar permissions without having to specify a single Identity as above.
Thanks

Hi
How can I list all existing calendar permissions for all mailboxes?
Hi,
I would also be interested to get a list for all existing calender permissions on all mailboxes. How?
Hi I would like to grant a single user access to all users calendar’s. How can I go about this?
That’s really helpful. Thanks. Any suggestions for a similar process in Exchange Online using Office 365 Groups. So all members in the group can e.g. be a Reviewer for each others calendar?
