Our service has a long-standing implementation of the List Item Delta API, but since Feb 10, it has started failing repeatedly with the following error:

Hi CAT,

Thank you for posting your question in the Microsoft Q&A forum.

Please note that our forum is a public platform, and we will modify your question to hide your request IDs in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data.

A 500 Internal Server Error with code: "generalException" from Microsoft Graph typically indicates the request reached the service, but something failed on the backend while processing it.

I also found other community reports around delta-related endpoints showing similar “generalException / 500” behavior, which helps corroborate that this may not be isolated to a single tenant or environment.

That said, to be fully transparent: this is a user-to-user support forum. Moderators, contributors, and external Microsoft employees participating here generally don’t have access to backend diagnostics or the ability to intervene directly in Microsoft Graph / SharePoint service internals. Our role is limited to sharing guidance and best practices based on what’s reported publicly.

Therefore, I kindly recommend that you consider submitting an official support ticket via Azure portal and include the request-id from a few failing samples. These identifiers allow Microsoft Support to correlate your failures with internal logs and provide the most accurate diagnosis and mitigation options.

While you’re waiting for Support to engage, if this issue is intermittent, a practical temporary mitigation is to implement retry logic with exponential backoff for transient 5xx responses to reduce impact while the cause is investigating.

Hope this helps.
