Can you edit a microsoft document stored on S3 with office 365 (2021)?

Viewed 217

is it possible to use the Office 365 API (which I believe is now called Microsoft Graph) to do the following:

  1. grant access to or download and upload an office doc to temporary Microsoft Storage
  2. let a licensed user edit the doc in Office 365
  3. upon save, download or programattically update the S3 file?

I found this post, but it's from 2015 and the link is dead.

Thanks for any help, Kevin

You should be able to handle the first two steps without a problem. Assuming they have the proper licensing, uploading a document to OneDrive and retrieving the resulting metadata will provide a URI you can use to open it in the correct Office application.

The challenge will be determining when they are done editing a document. The best option I can think of would be to use a delta query to determine if the file has changed. There are however some potential conditions (i.e. they could save a doc but still have the editor open) so you may want a 4th step where the user "checks in" the finished document.

The File Fabric from Storage Made Easy facilitates editing of Amazon S3 documents, including the collaborative mode, with Microsoft Office Online.
