1. Create a Word, Excel or PowerPoint file in Sharepoint online/Office365
2. Share the file with an account or group of accounts/policy
3. Copy the link to the clipboard
4. Copy the link into a Confluence page
5. Set the link display to “Embed”
6. You see the file embedded
7. Ask another Atlassian user to open this Confluence Page and view the embed/link

Expected Results

The second Atlassian user can resolve the smart link and view the data

Actual Results

The Sharepoint smart link does not resolve, and shows a forbidden access error.

Workaround

Second Atlassian user must open the Sharepoint file in Sharepoint first, then try resolve the smart link again.
