You will be prompted by the familiar Add New Account wizard. Once the relevant permissions have been assigned, go to Outlook, File, Add Account: The article above explains how you can add those, so I wont bother with the details. Full access, with or without Automapping, and recipient permissions in case you need them. So how do you actually access the shared mailbox? The answer is, you need to be granted permissions, much like accessing another user’s mailbox. Keep trying, it is not possible (anymore) 🙂 As the administrator you can of course change the credentials, apply a license to the user and try to access OWA/Outlook. In addition, the corresponding user object is automatically created, so credentials are hidden from you. When a shared mailbox is created, a special flag is set on the associated object in AD (ExchangeUserAccountControl), which will prevent you from logging in to that mailbox. This article will guide you on how to add a shared mailbox as a fully functional additional account in the same or new Outlook profile.įirst of all, forget about accessing the mailbox directly, it is not possible (anymore). Another example of why you would need to add a shared mailbox as additional account includes the situation when you would like to perform a Mail Merge and send the messages using the shared mailbox account. Other features will simply not work as expected, for example Private Items, Send on behalf/send As permissions. Example of such features/functionality include: Search, Inbox Rules, OOF replies, Categories, To-do lists. Outlook however will only expose certain features when the mailbox is added as normal (primary or additional) account. Most of those issues are caused by the fact that the shared mailbox is added as additional mailbox or automapped to the primary user mailbox. Unfortunately, there are still some common misconceptions around them, especially when it comes to ‘missing’ functionality.

There is a lot of information about them on the web, for example this TechNet article. Shared mailboxes are just one of the many great collaboration features of Exchange, and probably the most used one.
