LTI Microsoft 365 not working as it should - OneDrive SharePoint integration

[CaioSilva]

Hi everyone,

We have the following situation.

On our Canvas environment we use o Microsoft 365 / OneDrive to host our content.

For each course we create modules and items to the students as an extern url.

Until a few days it worked as it should, but then, out of nowhere it stopped sharing the items and contents with our students.

The URLs started stating that our sharepoint/onedrive environment has denied our connection.

see attached image.

So to summarize. Until a few days, our Canvas environment worked fine with M365 integration overt LTI. New External Link work, the whole lot of existing one do not.
