Additional sign-in or account-related issues within Microsoft Teams for business
Hi Amanda,
Regarding your concern, since you're using a work/school account, you need to have your organization’s Microsoft 365 administrator verify that a license containing Microsoft Teams is assigned to your account. Assigning a license requires at least the License Administrator or User Administrator role, while purchasing licenses requires an appropriate billing role.
Therefore, in this case, the best next step is to contact your company's IT department and ask for their help. They can help you check whether:
- Your account appears under Users > Active users in the Microsoft 365 admin center.
- A valid Microsoft 365 or Teams license is assigned to your account.
- Microsoft Teams service is enabled in your assigned license.
In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support.
Hope this will help. Should you have any other questions, please feel free to share them in the comments on this post. I'm happy to assist you further.
