Configuring message rules for a shared mailbox
Scenario: How do I access a shared mailbox and change a rule. I do have admin rights and full access to this mailbox but when I do a file > open> and try to change the rules, it reverts back to my primary mailbox rules.
Note: Exchange 2010 users cannot modify rules for mailboxes in Exchange 2013, and vice versa
There are several methods to get this to work:
Method 1: Outlook 2010 or Outlook 2013
Configuring Message rules for a shared Mailbox/Service Mailbox
If you are using Outlook 2010 or Outlook 2013 and either have been granted Full Access permissions to the mailbox or have been provided separate credentials for it, then you can also configure this shared mailbox as an additional Exchange account or add it as a secondary mailbox of your own.

Once the mailbox has been added, select its Inbox folder and add the rule as you would normally do for your own mailbox.
Method 2: Outlook Web App
When you have been granted Full Access permissions, then you can log on with your own username and password and click on your own name in the top-right corner to get to the option of opening another mailbox.
If you haven’t been granted Full Access permissions but do have separate log on credentials for the additional mailbox, you can use that to log on.
Once logged in, you can create a message rule in the following way:
