Question

How much time does the Copilot agent take to completely prepare using the provided knowledge (SharePoint files)?

AdityaSrivastava-1238 0

I created an agent using the Copilot Studio agent builder in Microsoft 365 Copilot. I added a few files from SharePoint as the knowledge base. However, it has been saying 'preparing' for the whole past day. How much time does it typically take to complete the preparation of the knowledge base?

P.S.: I have added one .txt file (222MB) and three .doc files (2MB, 8MB, and 15MB each).

According to this Microsoft article,

For SharePoint sources, if you don't have a Microsoft 365 Copilot license in the same tenant as your agent, generative answers can only process files up to 7 MB in size. You must also turn off the Enhanced search results feature.

If you have a Microsoft 365 Copilot license in the same tenant as your agent, the maximum file size is 200 MB. You must also turn on the Enhanced search results feature.

Larger files can be stored in SharePoint and are returned by a Microsoft Graph search, but aren't processed by generative answers. As an alternative, you can upload your own files, which can be up to 512 MB in size.

Same issue, with smaller files. I uploaded twenty .txt files, all under 10KB apart from two under 140KB, then requested the Python code snippets contained in them be ordered into a useful guide in two formats, .txt and .pdf . After three hours CoPilot sent a message that it was applying the finishing touches, and a day later (I prompted it a few times on the way) CoPilot was still optimistically chatting about links to the two guides being imminently available.
