Users need to resolve a specific error message that appears when exporting case or custom records from Dynamics 365 to Excel.

Fix Dynamics 365 Export to Excel Error: An Error Has Occurred {1}{0}

Product: Dynamics 365 / Excel
Device & OS: not provided
Scenario: Exporting case or custom data records from Dynamics 365 into an Excel spreadsheet format.
Observed behavior: The export fails with the message 'An error has occurred: {1}{0}'. This behavior is inconsistent, sometimes affecting specific browsers, zoom levels, or record types while other exports succeed.

Before you start

Ensure you have saved any active work in Dynamics 365 before refreshing your page, and verify whether the issue persists across different web browsers.

Solution 1Recommended

Adjust Browser Zoom Level and Refresh

Modifying your browser's zoom level is the most common workaround to fix this known display glitch, as the error is triggered by specific zoom and resolution combinations.

This is a known Microsoft issue where specific combinations of operating system display resolutions and browser zoom levels result in decimal-width values in network requests, causing the export to fail.

Change Zoom Level

Click the three-dot menu icon in the top-right corner of your browser (Edge or Chrome) and use the '+' or '-' buttons to zoom in or zoom out (e.g., change from 100% to 90% or 110%).

Refresh Dynamics 365

Press F5 or click the reload button to refresh the Dynamics 365 page completely.

Retry the Export

Attempt to export the records to Excel again. If the error persists, try another zoom percentage until the network request registers a whole-number width value.

Quick Fix: Many users report that simply zooming out once and refreshing the page completely resolves the problem.

Solution 2

Switch to Google Chrome or Clear Browser Cache

Because the error often isolates itself to specific browser environments like Microsoft Edge, switching to an alternative browser or clearing the current cache can bypass the problem.

Solution 3

Export Using Legacy Advanced Find

Disabling the modern Advanced Find feature forces Dynamics 365 to use the older, more stable interface for filtering and exporting records.

Frequently Asked Questions

Why does Dynamics 365 show 'An error has occurred {1}{0}' when exporting to Excel?

This is a known Microsoft bug that occurs when certain combinations of your operating system's display resolution and your web browser's zoom level create a fractional (decimal) width value in the system's network request. Dynamics 365 currently requires a whole number to process the export properly.

Is Microsoft going to fix this export issue permanently?

Yes. Microsoft engineering is aware of the issue and is actively working on a permanent fix. Once finalized, the patch will be deployed automatically to all Dynamics 365 environments, though there is currently no official estimated release date.

Why does the export work in Chrome but fail in Microsoft Edge?

Different web browsers render page zoom and scaling slightly differently. A zoom level of 100% in Edge might produce a fractional width value based on your specific monitor resolution, while Chrome might compute it as a whole number, allowing the export to succeed.

Will clearing my browser cache fix the Dynamics 365 export error?

While clearing the cache generally resolves temporary browser glitches and is recommended, this specific error is primarily driven by zoom levels and resolution. Clearing the cache may help if a broken view is stuck, but you will likely still need to adjust your zoom level.
