Add a "Shared" Mailbox to an Outlook Profile in Office 365

When you have multiple mailboxes in your Outlook profile, changes to "Rules" and "Out-Of-Office" replies only affect the primary account mailbox.  If you want to change the Out-Of-Office message for another mailbox, you must login as that mailbox.  This can be achieved by creating another profile.

• Close Outlook by selecting File --> Exit

• In Windows, click on Search --> Control Panel

• Click on the Mail icon

• Click on the Show Profiles... button
  
  
  

  Open

  

  
  
  
  

• Click on the Add... button

• Choose a profile name and select OK

• Select Manual setup or additional server types and click Next

• Select Office 365 and type the full email address of the mailbox, click Next
  
  
  

  Open

  

  
  
  
  

• If you see a prompt from autodiscover.xml, enter your Microsoft username.  ex a3morris@royalroads.ca (Academic Account Username + @royalroads.ca).

• Check Change settings and select Next

• Uncheck Use Cache Exchange Mode, and make sure there is NO check mark beside Set up Outloook Mobile on my phone, Too and click Finish

• Select prompt for a profile to be used and click OK
  
  
  

Now when you start up Outlook, you will see a prompt asking you which mailbox you would like to open.  Most often, you probably want the default, so you can simply hit the Enter key on your keyboard to go into your regular profile.  When you want to see the other mailbox, simply select the name from the dropdown list and click OK.

When you are ready to go back to your original profile, exit Outlook from File --> Exit, wait 5 seconds and then restart Outlook and repeat the process.

If you get tired of the prompt to select a profile, or no longer need it:

1. Close Outlook by selecting File --> Exit

2. In Windows, click on Start --> Control Panel

3. Make sure you are Viewing by "Small icons" and click on the Mail icon

4. Click on the Show Profiles... button

5. Select Always use this profile and then select the original default profile (usually called "Outlook")

6. Click OK and start Outlook normally.
