These steps will show you how to manually add a Shared Mailbox to your Outlook application on iPhone and Android phones.


Outlook Application on iPhone and Android doesn't support adding shared mailboxes automatically to your application, so, this needs to be done manually.

The steps below assume that your main account is already signed into the Outlook application.


  • At the top of the Outlook app, click on the circle icon next to the "Inbox" title, to open the slider menu.

  • Click on the "+" icon at the top left corner.

  • Click on "Add Shared Mailbox".

  • You will be prompted to type the email address of the shared mailbox you want to add. When you've finished typing the email address, click on "Add Shared Mailbox".


Be aware that Outlook will check whether you have access to the shared mailbox. If you don't have access, the shared mailbox will not be added and Outlook will display an error message.

  • If you have been given access to the shared mailbox it will be successfully added to your Outlook application, just below your main mailbox.
