Focused Inbox In Outlook Disappeared

Hi Ailene Sorice

I understand how confusing it can be when the Focused Inbox suddenly disappears in Classic Outlook.

In Classic Outlook for Windows, the Focused Inbox feature is available only when the mailbox is recognized as a Microsoft 365, Exchange, or Outlook.com account.

If you are using a custom domain, this behavior can be related to how Autodiscover is configured. In some cases, an unexpected response may cause Outlook to treat the account as non‑Exchange, which results in the Focused Inbox feature being removed. You may want to check with your domain or hosting provider to ensure that Autodiscover is configured correctly for Microsoft 365.

For more details, please refer to the following Microsoft article: Focused Inbox disappears when you switch folders in Outlook

Additionally, you may try creating a new Outlook profile to check whether the behavior is related to the current profile configuration.
