Additional meeting and call-related features and issues within Microsoft Teams for business
Hi John,
Sorry to know that you are experiencing this issue. Let me help you!
This is a per-user policy and applies during a meeting. This setting controls whether the Turn on live captions option is available for the user to turn on and turn off live captions in meetings that the user attends.
You can check this link to enable it: https://learn.microsoft.com/en-us/microsoftteam...
If the option is not present on your settings, please contact the Teams Administrator to check the meeting policy to enable the Captions.
Let me know if you need further help.
Best,
Jayzar
