Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Teams Rooms Basic must be added directly to your tenant through Microsoft 365 admin center → Billing → Purchase services; it is a Web Direct-only offer, so a CSP or sales partner cannot add it for you.^1^
Add the Basic subscription
Use an account with appropriate license-purchasing permissions:
- Sign in to the Microsoft 365 admin center.
- Go to Billing → Purchase services.
- Search for Teams Rooms.
- Open Teams Rooms Basic → Details.
- Select the required quantity—normally one for your Yealink system—and complete the purchase.
Although Basic has no license charge, Microsoft requires payment details to add it. The documented limit is 25 Basic licenses per tenant.^1^ The detailed acquisition sequence is documented here.^2^
If Basic is still missing
Since you already searched the Marketplace and only Pro appears, do not attempt to obtain Basic through your partner. Check these eligibility conditions:
- Tenant segment: Basic is available for Commercial, Education, and Non-Profit tenants. Unlike Pro, it is not listed for GCC, GCC-High, or DoD.
- Acquisition channel: Basic is Web Direct only; Pro is offered through additional channels such as CSP and enterprise agreements.
- Existing quantity: Check Billing → Your products or Billing → Licenses to determine whether the tenant already has 25 Basic licenses.
- Billing setup: Ensure the tenant has a usable payment method, even though the resulting Basic subscription is free.^1^
If the portal specifically reports “You don't have any billing accounts for buying products,” this is a billing-account permission issue. A Global Administrator can assign the required billing-account role; a Billing Administrator without access must ask the Global Administrator.^3^
If none of those conditions explains why Basic alone is absent, open Microsoft 365 admin center → Support → Help & support and request a Microsoft 365 commerce/billing investigation. Include:
- Tenant segment and billing country/region
- Screenshot showing Pro but not Basic
- Current Basic-license count
- Confirmation that the search was performed under Billing → Purchase services
- Confirmation that a payment method is present
The available documentation does not identify another self-service acquisition route when the eligible Web Direct offer is missing.
Assign the license to the room account
After Basic appears under your tenant’s licenses:
- Go to Users → Active users.
- Select the room resource account.
- Open Licenses and apps.
- Select Microsoft Teams Rooms Basic.
- Select Save changes.^4^
Also ensure the room resource account has a password and that Require this user to change their password when they first sign in is disabled; requiring that change causes Teams Rooms sign-in problems.^5^
Then sign the Yealink device in with that room resource account. Basic covers one certified Teams Rooms system per room; using the same account on multiple room systems requires Pro.^1^
