Every business says it wants data-driven decisions. Few agree on which data should drive them. Sales has one set of numbers, finance another, and operations keeps a spreadsheet that matches neither. Each figure is right within its own system, and none of them helps you decide anything.

The usual fix is a data warehouse that copies everything into one place. It settles the argument for a while, then slowly drifts out of date. Microsoft’s current answer for Dynamics 365 users is different.

With Microsoft Fabric, you can link the data in place instead of copying it around. This post explains how Dynamics 365 Fabric integration works, which route to pick, a few dates worth knowing, and what to fix before you start.

Why Dynamics 365 Data Ends Up Scattered

Dynamics 365 isn’t a single database. Customer Engagement, Finance and Operations, and Business Central grew up as separate products, each storing data in its own way.

Throw in Power BI reports, exported files, and a few homemade extracts, and the same customer ends up in half a dozen places with slightly different details.

That’s how a business ends up arguing about whose numbers are right instead of what to do next. We saw the same problem in the public sector in our guide to solving data silos in local government, and the pattern repeats everywhere.

One Copy Instead of Many

The idea behind Fabric is simple. OneLake acts as a single data lake for the whole organisation, and other sources can point to it instead of duplicating their data there.

For Dynamics 365, the feature that makes this work is Link to Microsoft Fabric. As Microsoft’s documentation explains, it makes your Dynamics 365 and Power Apps data available in OneLake as shortcuts, so you don’t need your own storage account or Synapse workspace.

Behind the scenes, the system maintains an optimised replica in Delta Parquet format, the native Fabric format, stored in Dataverse. This keeps your live operational workloads from slowing down.

Two practical points follow. The shortcuts are read-only, so analysts can work with the data without any risk of changing the source. And since there’s no pipeline to build, there’s less to maintain, which is why Microsoft prefers this route.

How Each Dynamics 365 App Connects

This is where things get less tidy, and a good plan matters. As one partner paper puts it, the Dynamics 365 family doesn’t have a single ingestion story.

Customer Engagement and Finance and Operations both surface through Dataverse, so they share the no-copy route into OneLake.

For Finance and Operations, this depends on Power Platform integration being switched on, and Microsoft’s guidance says the link covers all Dynamics 365 apps, including Finance and Operations. The Weidenhammer paper goes through the options in detail.

Business Central works differently. The same paper notes that it isn’t Dataverse-based, so there’s no first-party zero-ETL shortcut from Business Central into OneLake, and you’d need another approach.

If you run Business Central, it’s worth knowing that early, and it connects to the points in our Business Central and Dynamics 365 CE integration guide. For the customer picture across both, take a look at our piece on a single customer view.

Fabric Link or Synapse Link

Both names come up a lot, so let’s separate them. Azure Synapse Link for Dataverse exports data to a storage account you own, giving you more control but also more to manage. Link to Microsoft Fabric leaves the data in Dataverse and surfaces it in OneLake.

One more development makes Link to Fabric look even better. Microsoft announced low-latency sync for Link to Fabric on 9 June 2026.

Reports say it removes the intermediate CSV step, so Dataverse and Finance and Operations data goes straight to Delta Parquet in OneLake. Microsoft cites throughput of more than one million records per hour per table.

Fresher data helps finance teams catch exceptions sooner and gives AI agents live numbers to work with.

For most organisations already on Fabric, Link to Fabric is the sensible default. If you’re weighing up the options, we’d suggest choosing deliberately, because the right answer depends on how much control and how much maintenance you want.

Dates Worth Putting in the Diary

A few deadlines are shifting, and they matter if you currently export Dynamics 365 data to a lake. These come from partners tracking Microsoft’s notices rather than from a single Microsoft page, so check them against Microsoft’s own announcements.

  • Export to Data Lake for Finance and Operations. One partner reports that no new or changed data will flow after 30 November 2026, with no extension. If you still rely on it, plan for that date.
  • Delta Lake export in Synapse Link for Dataverse. Reported as deprecated, closed to new customers from 15 October 2026 and removed in December 2027, with Microsoft steering users towards Link to Fabric.
  • Bring your own database for Finance and Operations. No retirement date has been announced, though Microsoft recommends moving to Synapse Link or Link to Fabric.

The DataOpsMind summary of the Synapse changes makes a handy second opinion. One more practical note a partner guide says Link to Fabric from Finance and Operations needs Fabric capacity, while Power BI can run on standard licences without it. Check your own set-up before assuming either way.

What Unified Data Lets You Do

Once everything sits in one place, the questions get more interesting.

You can ask things that cut across the old boundaries, like how service cases affect renewals, or which customers stay profitable once finance’s costs are counted.

Power BI reads from the same OneLake data, which we cover in our guide to turning Dynamics 365 data into live Power BI dashboards.

The agents now showing up in Dynamics 365 also benefit, from the Dynamics 365 ERP MCP server to the ones we describe in agentic ERP. They do better work when the data underneath is joined up and current.

Fix These Before You Link Anything

Linking data doesn’t clean it. If your customer records are duplicated in the CRM, they’ll be duplicated in OneLake too, just faster.

Before you connect anything, agree who owns each data type and which system is the master. Clean up the obvious duplicates. Decide who gets to see what, because a lake that brings everything together can also expose everything.

Then structure the data sensibly once it lands, using the bronze, silver and gold layers we explain in our guide to building modern pipelines in Microsoft Fabric. And if you’re deciding when to transform data, our piece on ETL versus ELT will help.

Final Thoughts

Smarter decisions don’t come from more dashboards. They come from everyone looking at the same numbers. For Dynamics 365 users, Fabric finally makes that practical without the mountain of copying and reconciling.

Technology is mostly in place. What’s left is the unglamorous work ownership, data quality, access, and a clear plan for the dates above.

If you’d like a hand with this, our BI and Data Science services team plans and builds the connection between Dynamics 365 and Fabric.

Our AI Enablement Programme then helps you get that data ready for AI. As an ISO 27001-certified Microsoft partner, we treat access and data protection as part of the design.

Frequently Asked Questions

How do I connect Dynamics 365 to Microsoft Fabric?

For Dataverse-based apps, use Link to Microsoft Fabric to surface your data in OneLake as shortcuts, without a pipeline or an extra storage account. Finance and Operations data is included via Dataverse when Power Platform integration is enabled.

Does Link to Fabric copy my data?

It doesn’t create a separate copy for you to manage. Microsoft says the system keeps an optimised Delta Parquet replica in Dataverse storage, and the data appears in OneLake as read-only shortcuts.

Can Business Central link into Fabric the same way?

Not in the same way. One partner paper notes that Business Central isn’t Dataverse-based, so there’s no first-party zero-ETL shortcut and a different approach is needed.

What’s the difference between Fabric Link and Synapse Link?

Synapse Link exports data to a storage account you own. Fabric Link surfaces Dataverse data in OneLake without you needing to provide storage or a Synapse workspace.

Which deadlines should I watch?

Partners report 30 November 2026 as the end of Export to Data Lake for Finance and Operations, and 15 October 2026 and December 2027 for the Delta Lake export in Synapse Link. Confirm each against Microsoft’s notices.
