Hi
Please contact your administrator and follow the steps below to check whether the Outlook add-in policy is enabled for you in Teams admin center.
Sign into Teams admin center>User> Select specific user > Policies> Meeting policies> Meeting Scheduling> Outlook add-in.
After you enable it, wait for the policy to take effect, which is generally 48 hours. If this feature is enabled but still does not have options, refer to the fix in the article:
