Use the "Add More Products" Workaround

Bypass the E6118 error by initiating a new product purchase rather than updating the existing license count.

Some users have successfully bypassed this error by purchasing the licenses as a new transaction instead of modifying the existing subscription. Please note that due to Microsoft admin center updates, this option might be restricted to 'Manage' for some users.

1
Navigate to Products

Log in to the Microsoft 365 admin center and go to the Products view under the Billing section.

2
Select Add more products

Click on 'Add more products' and select the exact same Teams Phone product you currently hold.

3
Specify Quantity and Settings

Enter the additional quantity of licenses you need. Ensure your subscription settings and renewal dates are set to match your existing subscription.

4
Complete Purchase

Click 'Buy again' and follow the checkout prompts to place the order. This may create a separate subscription listing for the additional licenses.

Frequently Asked Questions

What causes error E6118 in Microsoft Teams?

Error E6118 is typically a backend billing or synchronization issue within the Microsoft 365 admin center when the system fails to process license expansions or new calling plan provisioning.

Why do I only see 'Manage' instead of 'Buy again' in the admin center?

Microsoft frequently updates the admin center interface and backend billing policies. If you only see 'Manage', your account may be restricted from creating overlapping subscriptions, meaning the workaround is unavailable and you must contact Microsoft Support.

Will error E6118 affect my existing Teams phone numbers?

No, this error is strictly related to purchasing and provisioning. It only prevents the addition of new licenses. Your currently active licenses, phone numbers, and calling plans will continue to function normally.
