How to give other user Read permission to all Outlook folders?

[Grace Yin]

Hi,

We use Outlook 2016 with connecting to Office 365. One user requests to give another use READ permission to all his Outlook folders including all subfolders. 

I noticed the permission are not inherited. For example, if the user A gave user B Read permission to Inbox folder, User B can only access Inbox folder. User B can not see any subfolders under Inbox folder. 

I wonder if there is a way to share all Outlook folders including subfolders Read permission to other people. We don't want to give user B Full Access on the server end.

Need help!

Thanks in advance!

You will have to enumerate all the folders and grant permissions to each of them. Here's a script I wrote a while back to get you started: https://www.quadrotech-it.com/blog/setting-mailbox-folder-permissions-in-bulk-via-powershell/
