Hi Nick
Thank you for reaching out to Microsoft Q&A Forum and sharing your experience.
I understand how frustrating this experience can be, especially when you already have the desktop apps installed and expect shared files to open smoothly.
Based on your description, this behavior may indicate a sign‑in or account context issue. When a shared document opens via a onedrive.live.com link and redirects to the web sign‑in page, an existing browser sign‑in with a personal Microsoft account can cause the authentication attempt to target the wrong tenant, resulting in sign‑in failure.
To help resolve the issue, please try the following steps:
- Sign out of all Microsoft accounts in your browser, or open the shared link in a private/incognito window, then sign in using only your university account.
- Verify that Word and PowerPoint on your Mac are signed in with the same university account that the file was shared with.
- Sign in first at https://www.office.com, then navigate to Shared files from there instead of using the direct link.
- If the issue persists, please contact your university IT administrator and provide the Correlation ID and timestamp you included.
Please let me know how things go on your side as your update can also assist others in the community who may be facing the same issue.
