Hi,

during trying of configuration permissions for Calendar on Office 365 (maybe on Exchange 2013 will be same), i found some strange:

PS C:\> get-MailboxFolderPermission -Identity "office\calendar"

FolderName           User                 AccessRights
----------           ----                 ------------
Top of Informatio... Standard             {None}
Top of Informatio... Anonym               {None}

and another folder:

PS C:\> get-MailboxFolderPermission -Identity "office:\calendar"

FolderName           User                 AccessRights
----------           ----                 ------------
Calendar             Standard             {AvailabilityOnly}
Calendar             Anonym               {None}
Calendar             user1                 {PublishingAuthor}
Calendar             user2                 {PublishingAuthor}
Calendar             user3                 {PublishingAuthor}
Calendar             group1               {PublishingAuthor}

the difference in office:\calendar or office\calendar without colon. These settings are for one mailbox, but why it has TWO different Calendar folders with different permissions?

Hi,

First one shows permission levels at the top level and the next one is the granular level permissions (When you grant a use the owner permission for a folder, the user has CreateItems, ReadItems, CreateSubfolders, FolderOwner, FolderContact, FolderVisible, EditOwnedItems, EditAllItems, DeleteOwnedItems, DeleteAllItems permissions) 

doest it mean, that one folder Calendar has two level permissions?

Hi,

That doesn't mean calendar has two level permissions. Actually the first command gets the folder permission on this user, not on this user's calendar. If you run this command, the result will be the same.

Get-MailboxFolderPermission -Identity "office"

The "Top of Information Store" represents the root folder your mailbox.

Best Regards.
