Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear John Peter1,
Good day! Thank you for posting to Microsoft Community.
To answer your questions, Yes, you can extend the free trial for Microsoft 365 Business Premium, but there are some conditions. If your trial subscription is within 15 days of expiring and hasn’t been extended before, you can extend it for another 30-day period, you can only do this one time. Therefore, If your Microsoft 365 Business premium subscription trial is within 15 days of expiring, you can refer to this article and follow the steps to extend your trial, see Try or buy a Microsoft 365 for business subscription | Microsoft Learn
If you have any other questions or need further clarification, please let me know.
Thank you for your precious time. Have a nice day.
Sincerely,
Libeamlak | Microsoft Community Moderator
