Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I have been waiting for only 1 day for MSFT to resolve this for me. Seeing these comments prompted me to look for workarounds. Happy to report that I found one that allowed us to purchase additional licenses and keep the business moving. Here is what I did after receiving the same error message as OP, when trying to "Buy Licenses" on an existing 365 Business Premium product:
- Go to
Add more productsin the your products view - Select the same product you are trying to buy additional licenses to
- Select the plan, select license quantity, subscription length and, billing frequency (all of which are the same as your original line item)
- Select Buy again (instead of manage)
- Change the renewal date to match your existing product for the same license
- Place order
This works. The only downside I can see now is that I have a duplicate listing of the 365 Premium product; the first with the existing quantity which I wasn't able to increase through the traditional "Buy licenses" option and the second being the new purchase for additional licenses (of the same product).
Hope this helps and makes sense.
