I have created a service account. I want to grant Exchange Permissions for this account so that the service account can create tasks as well as create calendar entries against every mailbox on our Exchange Platform. I am pretty sure this can be done, but don't want to give them too many perms if at all possible. I would think I could do this in Powershell, but not sure. TIA Martin P.

Hi, This service account must have the full access permission of each mailbox. You can use the following exchange shell to give full access permission to all mailboxes: Get-mailbox | Add-MailboxPermission -User Genlin -AccessRights FullAccess Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Gen, Thanks for the info. That solution was exactly what I was looking for. Regards, Martin P.
