Outlook Send as (delegate) permission error

Question

Hello,

we have recently the problem that one person is sending cancellation of meetings "on behalf" of somebody, without that the person has any delegate permission.

That person has not been assigned a delegate permission for that user/mailbox, as I can see on the Exchange Admin Center (Online). How is this possible?

Hi @ Ramesh Raja,

 

In addition to the Send As permission, I recommend that you check that User A's calendar delegation is granted to User B.

You can do it by following these steps:

1. In Outlook on the web, select the Calendar icon at the right of the page.
2. In the navigation pane, right-click the calendar you want to share, and then select sharing and Permissions.
3. In this window, you’ll see a list of people who have access to your calendar. If someone is a delegate, they’ll have the Can edit or Can edit and delete permission level.

You can also check the permissions that user B has in User A's calendar folder by referring to the following command in Exchange Online PowerShell:

Get-MailboxFolderPermission -Identity UserA@contoso.com:\Calendar -User UserB@contoso.com
