How to access Outlook 365 Online to give Read permission to other users?

Copper Contributor

The Office 365 Admin console only have 3 options: Read and Manage, Send as, Send on behalf

I need to provide Read permission to other users (without Manage) so it's not possible to do it through the Admin Console.

This account has E1 license which can only be accessed through the Outlook Online app (no desktop app).   I cannot find the permission setting on the Online app.

Is there any way to grand READ only permission for calendar/mailbox of this account?

Hi @JohnIFSE 


I believe you are still able to amend a folders permission in OWA by right clicking on the folder and selecting 'permissions'




The other way to do - and the way I personally prefer - is to use Powershell and the Set-MailboxFolderPermission cmdlet.


Not sure how familiar you are with Powershell, so apologies if it seems like I'm teaching my mother how to suck eggs, but you can connect onto Exchange Online in Powershell, then add granular permissions to specific folders (i.e. Inbox, Calendar etc) to specific users that way. It's command line based, but I find it easier to work with.


Just in case you need it, here are some resources to point you in the right direction.

One thing with the cmdlet that might help you because I got stuck on it: the mailbox is set up as a tree with the Top of Store being the very first level, then you have inbox, calendar sent items etc below that, and any sub folders those folders might contain. For a user to get to those subfolders, they must have the "FolderVisible" permission at the top of the store - this lets them see the folder, but not the contents.


i.e. you want to give UserB read permissions to UserA's Inbox and Calendar, but not sent items.


First give UserB "FolderVisible" to the top of UserA's store


Add-MailboxFolderPermission -Identity -User -AccessRights FolderVisible


Then add permissions for inbox and calendar


Add-MailboxFolderPermission -Identity -User -AccessRights ReadItems


Add-MailboxFolderPermission -Identity -User -AccessRights ReadItems


Apologies for waffling on a bit, but I hope this helps.

@HidMov Thanks very much.  Worked!
