If your Business Central runs on-premises, Microsoft changed the rules on 5 June 2026. The change itself is small. Missing it is not, because it can stop your on-premises system from running.
In short: Business Central online customers who also run an on-premises deployment under Dual Use Rights now have to download and replace their licence keys every six months. If Braintree looks after your Business Central, this is already on us.
What changed
Effective 5 June 2026, any Business Central online customer running an on-premises deployment through Dual Use Rights must download and replace the licence keys every six months to keep using the on-premises product. Those keys are what allow the on-premises environment to run, and they are tied to the term of your Business Central online subscription. Once a key reaches its end date, plus a short buffer period, the on-premises environment can no longer be used on that key.
Who this affects
This only matters if you run Business Central on-premises under Dual Use Rights, which means you hold a Business Central online subscription and use it to license an on-premises install as well. If you run Business Central purely in the cloud, nothing changes for you. If you are not sure which describes your setup, that is exactly the kind of thing we can confirm in a minute.
What to do
- Download new or replacement Dual Use Rights licence keys from the Microsoft 365 Admin Center.
- Repeat every six months, before the current keys expire, so there is no gap.
- Do not lean on the buffer period. Using the licence beyond the subscription term, including the buffer, is not permitted.
If we manage your Business Central, keeping these keys current is part of looking after your environment, so there is nothing for you to chase. If you manage it in-house, put a six-monthly reminder in place now.
Not sure if it affects you?
For most cloud-only customers this is a non-event. For the smaller group running on-premises or hybrid, it is worth getting right. Chat to a Braintree consultant and we will check your setup and tell you plainly whether you need to act.
