Shared mailbox not showing up in Outlook
Outlook needs to catch up after you're added to a shared mailbox. The quickest fix is to close Outlook completely and reopen it. This forces it to refresh your mailbox list. If that doesn't work, add the shared mailbox manually by typing the email address in Outlook settings.
When IT adds you to a shared mailbox, Outlook takes a few minutes to notice and display it. If it's been more than a few minutes, Outlook is out of sync with Microsoft 365. Restarting Outlook clears out that confusion and makes it refresh. If restarting doesn't work, you can add the mailbox manually through your account settings.
Fix-IT-Bot will walk you through each step — just tap, no typing needed.
Skip — I just want a technicianCommon mistakes to avoid
- Thinking you need to add your own email address as the shared mailbox. You add the shared mailbox's email address, not your own
- Restarting just Outlook instead of fully closing and reopening it. The app can still be running in the background
- Assuming IT granted access without checking if the permission actually took effect
Signs you need professional help
- If you've restarted Outlook multiple times and the mailbox still won't appear, the mailbox shows in Outlook on the web but never appears in the Outlook app after restarting, or you're getting an error message when trying to add the mailbox manually, get in touch and we'll help you out.
