Usermailbox in Office 365 with read only permissions

MVP

Hi Folks ,

  I have a customer requirement where users should have read only access on their own mailbox . They should only be able to see the incoming emails but they shouldn't be able to delete it ,reply to it ,  forward it or anything else apart from just reading the email which comes to their inbox . How can this be achieved ? I tried the PowerShell commands but I couldn't find the right one as most of them where talking about setting permissions on another user's mailbox or permissions on a shared mailbox but none of them were related to altering the  existing permissions on the user's own mailbox . Could you folks please check and help me with some steps to achieve this ? Thanks in advance .

This is a really unusual request to place such limitations on a users own mailbox.  I'm not aware of any controls you could put in place to achieve this.  

 

However, you could try setting a transport rule to block outgoing messages from these users.  This would prevent them sending/replying/forwarding.  

 

The deleting messages part is a bit trickier.  You may want to look at retention policies as an option here perhaps and apply a retain forever policy to the mailbox?

Hi @VigneshGanesan, just use a mail-enabled Public folder instead of a user's mailbox.
