Microsoft 365 Copilot in Outlook can now do more to help you manage your inbox by directly generating draft emails, creating and managing rules, as well as supporting many more triage actions.
Just tell Copilot what you need, and it thinks through each step and action with clear reasoning, ensuring you have visibility along the way.
Opening Copilot Chat in Outlook will enable “Allow actions” mode by default (Frontier only). Users can choose to toggle back to the chat-only Copilot experience via the dropdown just above the prompt box:
With your direction and guidance, Copilot can provide a wide range of mailbox functionality including:
-
Move emails from a specific sender to a folder
-
Archive messages you identify in chat
-
Flag emails for follow‑up
-
Create a rule to organize future messages
When will I see the changes?
This update is available only to users who are part of the Frontier program. If your organization is enrolled in Frontier, the new default experience will begin rolling out starting April 27, 2026, and is expected to complete by April 28, 2026. Outlook may need to be restarted for the change to take effect.
The new default experience updates your mailbox at the service level.
In some Outlook clients, these updates may not appear immediately due to synchronization timing between the service and your local mailbox.
For example:
-
Folder creation or category updates may require a refresh before appearing
-
Changes made in cached mode may take additional time to appear locally
This behavior can vary depending on your client and the current state of mailbox synchronization.
As a result:
-
Changes are typically reflected immediately in online experiences such as Outlook on the Web
-
In classic Outlook, the updated mailbox view may lag until synchronization completes
Things to keep in mind
In this release:
-
Bulk automation across large sets of emails results may not be comprehensive
-
Some tasks that depend on pattern detection across many messages may not be available
Support for additional capabilities may be added in future updates.
