Create an Outlook for Windows Profile for a Shared Mailbox

Adding a shared inbox as a separate mail profile in Outlook is a good way to keep sent messages and received messages in their correct respective folders, rather than loading it up alongside your personal Outlook profile.

NOTE:

These instructions assume you already have access to the shared email box that you wish to setup in Outlook for Windows.
These instructions assume you already have your own personal Pomona College email account setup in Outlook for Windows (please click here if not).
Please note: some icons may differ in coloration that the screenshots provided due to the varying version of Windows in use on campus; these steps remain the same for all versions of Windows.

The Setup

Make sure Outlook is closed before proceeding.
In the Windows search menu, type 'Control Panel'. Then, click on the 'Control Panel' option when it appears above.
Inside the Control Panel, you may need to change the view to see all the options available. If you only see 6 or so large icons, click the 'View by' button in the upper right of the window and change it from 'Category' to 'Large icons'.
Inside the list of icons, open 'Mail (Microsoft Outlook)'.

NOTE:
Which icon you have depends on your operating system version, but they're functionally the same.
In the 'Mail Setup' window, click 'Show Profiles'.
Click 'Add'.
Type the name you want to give the account profile. It is best to use the name of the mailbox being added.

Then, click 'OK'.
In the Auto Account Setup, click on the 'Manual setup or additional server types' option. Then, click 'Next >'.
Under the 'Microsoft 365' option, type in the email address of shared mailbox. Then, click 'Next >'.
In the 'Congratulations' window, check the 'Change account settings' option. Then, click 'Next >'.
In the 'Server Settings' window, check the 'User Cached Exchange Mode' option and change the 'Mail to keep offline' option to 'All'. Then, click 'Finish'.
Back at the profiles window, check the 'Prompt for a profile to be used'. Then, click 'Apply' and then 'OK'.

NOTE:
This will allow you to select an account profile to use when opening Outlook for Windows.

The next time you open Outlook for Windows, you will have a choice of profiles to use, including the newly added shared mailbox.
