This question is from a user with a shared mailbox in his profile:
When I send new messages from the shared mailbox, the default address is my own address, not the shared mailbox address and I need to select the shared mailbox as From address. Other accounts default to using their own address. How can I set the shared mailbox account as default 'From address'?
Outlook will use the address assigned to the currently selected mailbox or data file as the default address if it is configured as an account in File, Account Settings. Because a shared account is a secondary account in your profile, Outlook won’t use that address by default when viewing the mailbox.
The only way to get around this is to add the shared mailbox to your profile as a mailbox. There can be issues if you have delegate permissions on the shared mailbox or it’s automapped (eg, is added to your profile automatically), so you or your admin will need remove delegate permissions or disable automapping before you add it to your profile. To avoid these problems, create a new profile for the shared mailbox instead.
If the mailbox is added using the Open Additional mailbox command in Account Settings, remove the mailbox from your profile in File, Account Settings, More Settings, Advanced.
Using the simplified account dialog
Use these steps with the new, "simplified account dialog".
- In File, Account settings, choose Change Profile
- Outlook will close; click on your Outlook shortcut to reopen it.
- Click New
- Enter the shared mailbox email address in the address field. Click Connect
- When the Enter password dialog opens, click the Sign in with another account link
- Enter your email address or signin name. click Next
- Enter your password. Click Sign in
- After the wizard finishes, open Outlook using this profile.
Using older versions of Outlook
Use these steps with older versions of Outlook or with the Manage Profiles option in Outlook 2016 and newer.
- Close Outlook and open Control panel then search for Mail.
- Select your Profile and click Properties to open your profile
- Click Email Accounts
- Click New to add a new account to your profile.
- Type in the email address of the shared mailbox and anything for the password.
- After autodiscover finds the account, the password dialog will come up.
- After the wizard finishes, reopen Outlook.
Outlook will now treat it like any other folder. When you send new mail while viewing the folder, Outlook will send it from the account.
