How to add a shared mailbox in Nine.

It's a kind of workaround even though this isn’t standard behavior or common practice as only users with permission that can access a shared mailbox, now you can access the shared mailbox with Nine and it does work only with Office 365! This way is to register the shared mailbox as an IMAP account. Please follow the below steps.

1. Go to the following path.

    Nine - Settings > Add Account

2. Type a shared mailbox of your organization in the "Email address" field. (i.e., shared_mailbox@example.com) 

3. Select “Manual setup". 

4. Select "IMAP".

5. Fill out the following information in the "Add your IMAP account" screen.

• Email address – shared_mailbox@example.com
• Password - type the password of your account that has permission on the shared mailbox. 

The "Manual Setup" will be activated if you input the password. And then, tap "Manual Setup".

Now the screen you are seeing is the setup screen of the incoming mail.

            your email address\shared_mailbox@example.com (for example, john.doe@example.com\shared_mailbox@example.com)
