Solution 1Recommended

Request Backend Recovery via the Power Automate Community

Since missing model data is a service-side issue, submitting a detailed report to specialists in the official community is the most effective way to recover your work without manual retagging.

Data loss during AI Builder retraining is typically related to service-specific behavior or temporary backend glitches rather than an unrecoverable user error. Microsoft engineers can often locate the disconnected data and restore it.

Gather your model's details

Compile the essential information regarding your model, including the model type (e.g., Document Processing), the timestamp of the retraining attempt, and any relevant error text.

Access the AI Builder Community

Navigate to the official Microsoft Power Automate Community website and log in using the Microsoft account associated with your Power Platform environment.

Post your recovery request

Create a new topic detailing your missing collections and documents. Provide the collected details and explicitly ask specialists to investigate if data can be recovered from the backend.

Hold off on manual re-uploading: Avoid immediately re-uploading and retagging your documents. Wait for a community specialist to respond, as backend recovery can save you hours of manual labor.

Frequently Asked Questions

Why did my documents disappear after retraining the AI Builder model?

This usually occurs due to a synchronization glitch or service interruption on the backend during the model's retraining phase. The data is often still present on the server but fails to render in the user interface.

Do I have to re-upload and retag all my missing documents?

Not necessarily. In many cases, support specialists can investigate the backend logs and recover your disconnected documents, preventing the need for tedious manual retagging.

What information should I include when reporting AI Builder data loss?

To expedite the investigation, always provide your AI model type, the precise date and time the retraining was executed, your region, and any correlation IDs or error codes that were displayed.
