Managing calendar permissions in Exchange Server 2010

Admin may get asked to set and add / Edit permissions for shared Calendars.
these Sharing options are not available in EMC, so we have to use exchange power shell on the server to manipulate them.

View existing Calendar permissions

Get-MailboxFolderPermission -identity "Networking Calendar:\Calendar"

There are 4 MailboxFolderPermission cmdlets in Exchange Server 2010:

• Add-MailboxFolderPermission

• Get-MailboxFolderPermission

• Remove-MailboxFolderPermission

• Set-MailboxFolderPermission

Each cmdlet have different syntax, follow the links for more information..

In this scenario we need to set following permissions to the Calendar Resource named "Networking Calendar.

user - "Nyckie" - full permissions


all users - permissions to add events without the delete permission

• To assign calendar permissions to new users  "Add-MailboxFolderPermission"

Add-MailboxFolderPermission -Identity "Networking Calendar:\Calendar" -User [email protected] -AccessRights Owner

 

• To Change existing calendar permissions  "set-MailboxFolderPermission"

set-MailboxFolderPermission -Identity "Networking Calendar:\Calendar" -User default -AccessRights NonEditingAuthor

 

This assigns the owner righs to the user "nyckig" for the calendar of the "Networking Calendar" resource.and sets NonEditingAuthor permissions as the default permission for the calendar for all other users
