How to set access rights for calendars in Exchange 2010

Since most of our users at work run on Macintosh, we have them use OWA exclusively. One caveat to doing so revealed a hope-to-be-resolved-soon bug which no doubt other OWA users will observe along the way-a user cannot share their calender with permissions greater than “Reviewer”. The workaround at the moment requires server-side resolution, which from a sysadmin’s perspective, is not welcomed overhead in managing an already expansive system such as Exchange. It is easy enough however, to extend permissions on user’s calendars. The following is an outline to do just that:

Cmdlets used:



Remove-MailboxFolderPermission-(this cmdlet is used to remove an existing coworker who was added before discovering it cannot be done in OWA).


Get-MailboxFolderPermission –identity david.bolton:calendar

Remove-MailboxFolderPermission –identity david.bolton:calendar –user my.coworker

Add-MailboxFolderPermission –identity david.bolton:calendar –user my.coworker –accessrights editor
