My email sends from me, not the shared mailbox
You have access to a shared mailbox, but your messages still go out under your own name.
The From button is what lets you pick which address a message goes out as. Outlook hides it by default, which is why most people never find it.
Do this first: turn on the From button
New Outlook, or Outlook on the web
- Click the gear icon in the top right.
- Choose Mail, then Compose and reply.
- Under Message format, tick Always show From.
- Save.
Classic Outlook on Windows
- Click New Email.
- Go to the Options tab.
- Click From in the Show Fields group.
Once it is on, it stays on for future messages.
Then pick the shared address
- Start a new message.
- Click From.
- Choose the shared mailbox from the list. If it is not there, click Other email address and type it, for example
office@yourcompany.com.
Send as usual. People who receive it see the shared address, not yours.
Worth knowing. Outlook remembers the last address you used. If you send from the shared mailbox all morning and then write a personal note, the From line may still say the shared address. A quick look before you press Send saves an awkward one.
Did this not sort it out?
If the shared address is not in the list even after typing it, either the permission has not reached your computer yet or the mailbox is not loaded. Start with The shared mailbox is missing in Outlook, and tell us if that does not sort it.
Tell Michael which step you got to and what the screen says. A photo of the screen from your phone is perfect.
