History
11/5/2026 Item Added to Message Center
Microsoft Message
Microsoft Teams mobile users will be able to decline an incoming Teams call and send a message to the caller at the same time. This gives users a faster way to communicate their availability without answering the call or separately navigating to chat.
From the incoming call screen, users can select Message and choose a predefined response or select Custom to compose a personalized response in the relevant Teams chat.
Rollout schedule
General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out in early December 2026 and expect to complete by mid-December 2026.

What will happen
Once this feature is available:
- Users will see a new Message option on the incoming call screen.
- Users can choose a predefined response, such as “Can I call you later?”, “I’m on my way.”, or “Sorry, I can’t talk right now.”
- Selecting a predefined response will decline the call and immediately send the selected message to the caller in Teams chat.
- Users can select Custom to decline the call and open the relevant Teams chat to compose a personalized response.
- The response will appear in Teams chat so users can continue the conversation after the call is declined.
- This capability will not apply to PSTN, anonymous, or interoperability calls where there is no corresponding Teams chat to receive the message.
- Existing options to accept or decline an incoming call will not change.
- The feature will become available automatically as it rolls out to eligible users.
