The purpose of this post is to create a Business Central Known Issues and Resolution List for the community. We will keep this list updated over time so you always know what’s going on and how to handle it.

New (preview) version of Copilot Studio and Business Central MCP Server – tools do not load
Issue Created on: 23/06/2026 12:58 PM IST
Status: Open
Problem Details
We are currently experiencing temporary issues with the integration between the new (preview) version of Copilot Studio and the Business Central MCP Server through the Power Platform connector. As a result, users may encounter the error message “Couldn’t load MCP tools”. This issue is related to missing default environment and company configuration settings.
Workaround Steps

Until the fix is released, Microsoft recommends using the previous Copilot Studio experience by switching to the legacy version using the toggle located in the top-right corner of the application.
OnPrem Timeline shows incorrect “Case resolved by” header for canceled Incident Resolution records after case reactivation in Dynamics 365 (on-prem)
Issue Created on: 23/05/2026 04:50 AM IST
Status: Resolved
Problem Details
Note: This issue only affects the on-premises version of Dynamics 365 and does not occur in the online version.
When a Case is resolved, reopened (reactivated), and then resolved again in the on-premises environment, the Timeline displays incorrect information for the original case resolution entry.
Expected behavior (same as Dynamics 365 Online):
- The original case resolution record, which becomes canceled after the case is reopened, should display “Case re-activated by “.
- The new resolution record created after resolving the case again should display “Case resolved by “.
Actual behavior in Dynamics 365 On-Premises:
- Both resolution records display “Case resolved by “.
- The canceled resolution entry incorrectly shows the user who reopened the case as the person who resolved it, instead of showing the original user who actually resolved the case.
Possible impacts:
- Dynamics 365 Sales
- Dynamics 365 Customer Insights – Journeys (former Marketing)
- Dynamics 365 Customer Insights – Data (former Customer Insights)
- Dynamics 365 Customer Service
- Dynamics 365 Contact Center
- Dynamics 365 Field Service
- Microsoft Dataverse
- Dynamics 365 Business Central
Workaround Steps

E-Document email sending fails when no existing E-Document is created before send

When you try to send a posted sales document as an E-Document by email, it may fail if the E-Document has not been created yet.
This happens because the system looks for an existing E-Document before sending the email. If it doesn’t find one, it stops the process and the email is not sent.
You will see this issue when you choose Send -> Email from a posted sales invoice that has not been processed as an E-Document.
Workaround Steps

- Until then, advised us to avoid the problem by first creating the E-Document manually:
