If you run Dynamics 365 Sales Enterprise and need more Dataverse capacity, a recent licensing change is worth a closer look.
In March 2026, Microsoft increased the default Dataverse capacity included with Sales Premium licences.
You can mix Enterprise and Premium licences in the same tenant, with no minimum purchase, so upgrading to a single Premium licence now lifts default allocation, often at a lower cost than the equivalent Dataverse add-on.
What Microsoft changed
The Sales Premium uplift covers two of the three Dataverse storage types.
Default Database capacity rose from 30 GB to 45 GB. Default File capacity rose from 40 GB to 60 GB. Log capacity remained at 2 GB.
This follows the broader December 2025 increase that raised default capacities across many Dynamics 365 and Power Platform applications, as covered in our article.
The March 2026 update applies specifically to Sales Premium.
When a Premium licence boosts the tenant default
Microsoft applies default Dataverse capacity at the tenant level. Sales Premium now has its own line in Microsoft’s licensing guide (shown below) with a higher default capacity than Sales Enterprise.
With no minimum Premium count required, a single Sales Premium licence is enough to shift the tenant baseline. Remaining Sales Enterprise users can continue working as before with their existing licences.
For a tenant currently running Sales Enterprise exclusively, this provides a 15 GB increase in Database default capacity and a 20 GB increase in File capacity.
Also, any additional Premium licences accrue Database capacity at a higher rate per seat at 500 MB versus 250 MB for Enterprise.
The commercial picture
A Sales Premium licence is approximately £115.30 per month (commercial pricing with an annual term payable upfront). Sales Enterprise costs £80.70 per licence per month on the same basis.
Upgrading a single Enterprise licence to Sales Premium adds £34.60 per month. The extra Dataverse capacity you gain would cost over £400 per month if purchased using a Dataverse add-on:
- Database 15 GB: £369.60 per month (15 x £30.80 per GB)
- File 20 GB: £30.80 per month (20 x £1.54 per GB)
- TOTAL: £400.40
That’s an annual saving of over £4,000.
Treat these figures as indicative. Pricing varies by purchase channel, term, and the specifics of your Microsoft agreement.
The Premium licence holder also gains the additional Sales Premium features included with that SKU, a useful side benefit for whoever takes the licence, even when storage is the primary driver.
Where this fits in
Purchasing a Dynamics 365 Sales Premium licence is one tactic to maximise capacity. It probably isn’t worth it if you have comfortable Dataverse headroom, but it will likely fit well when:
- You already pay for Dataverse capacity add-ons.
- You receive Microsoft notifications that capacity is approaching its limit.
- File capacity fills faster than expected, often the case where attachments accumulate against emails and notes.
This sits alongside other approaches to managing Dataverse costs, including archiving older data to Azure Blob Storage and using Dataverse retention policies. The right combination depends on your data profile and retention requirements.
You can check current Dataverse usage in the Power Platform admin centre under Resources > Capacity > Summary.
Reviewing whether this fits your situation
If Dataverse consumption isn’t a pressing issue, you can park this until your next renewal. However, if you are already paying for add-ons, it’s worth running the calculation now. These figures give you a starting point for a conversation.
The comparison is straightforward: the cost of upgrading a Sales Enterprise licence to Sales Premium against your current or projected spend on Dataverse add-on capacity.
