Delegate to many Mailboxes

I have a user that has been made the delegate of many shared Calendars and would like to be removed as such. Is there a PS that would identify the mailboxes the user is a delegate of, and remove her?

thank you!!

Try something like this (replace on the last line):

$calendars = Get-Mailbox -RecipientTypeDetails UserMailbox | Get-MailboxFolderStatistics | ? {$_.FolderType -eq "Calendar"} | select @{n="Identity"; e={$_.Identity.Replace("\",":\")}}

$calendars | % {Remove-MailboxFolderPermission -Identity $_.Identity -User }

Open in new window

Oh, it will give you errors for mailboxes on which she's not a delegate, but nothing bad will happen. If you want to get rid of the errors, just put a simple if check (though it will make the execution twice as slow!).

The person still needs full access to the Calendar. She just needs to be removed as a delegate to avoid receiving constant Calendar reminders

Oh, I see, that delegate option. You cannot control that with the built-in PowerShell cmdlets. You either have to use Outlook to disable it, or to use some EWS based script as for example:

Put all the users she has access to in a list and name it as users .csv file  then the file in your temp directory or wherever you want then run the below command

import-Csv c:\temp\users.csv | foreach-object {set-mailboxfolderpermission -Identity usernameofthedelegate:\calendar -AccessRights Reviewer}

change the command to wherever your csv is and after -AccessRights give the level she needs
