Dynamic 365 Business Central Attach license
Hello!
Regarding the new Business Central Attach license, what are the rules for storage?
According to the licensing guide, attach licenses do not add any extra storage. So, let's say a customer is planning to buy Dynamics 365 Sales Enterprise and also Business Central as an attach.
Will that customer then be able to use the 80 GB of storage included in the base license (without necessarily buying a base license?), or will the customer only have access to the application and need to purchase additional storage for Business Central separately?
- Hi,
It is correct the attach licenses do not provide accrued storage, but by default the Business Central instance will be provided with the default/base 80Gb capacity, even if you only use attach licenses.

The D365 Sales license does not include 80 MB of BC storage; however, the BC Database capacity is 80 MB. See pg.40 of the D365 LG for details:
To summarize Business Central database capacity (for the tenant) & storage per user:
Base and attach licenses are identical in their core capabilities. See pg.5 of the current D365 LG:
