NOTE: These instructions apply to the latest version of Outlook 365/2016 for Windows.

Once you are granted access to a shared mailbox, you will need to configure it as an additional account in Outlook.  This will allow you to send messages from the shared mailbox with the "from:" address as the e-mail address of the shared mailbox, have the sent messages saved in the sent items folder of the shared mailbox, and configure mail rules and signatures for the shared mailbox.

1. Launch Outlook and click on File tab.

2.  Click on Add Account button.


3.  On the Outlook screen, enter the address of the SHARED mailbox in (ie ) format and click the Connect button.


4.  Do not enter your password when prompted. Instead, click on Sign in with another account link located down at the bottom of the Enter password screen.

5.  Under Work or school account, enter your own e-mail address in this format: and click Next.

6.  Enter your password and click the Sign in button.

7. You may be prompted to once again enter a password. Once more, instead of entering a password click on Sign in with another account link on the bottom of the screen.

8. Click on your account to complete the sign in process.

9.  Uncheck the box next to "Setup Outlook Mobile on my phone, too" and click Done to complete the process.
