Issue Status: ONGOING

Issue Description: Microsoft Teams meeting participants may not be granted permissions to meeting notes added after meeting creation.

More info: This issue only occurs in organisations where admins have enabled the ability for users to share links with “Specific People” in Microsoft OneDrive and SharePoint Online as the meeting notes are hosted there.

When users add meeting notes from the Microsoft Teams Calendar to a meeting that has already been created, the meeting participants may not be granted permissions to view the notes, while the user that added the notes may be able to access them as expected.

Current Update: 06/02/2026 08:46:00 AM –Microsoft has isolated a misconfiguration which resulted in a subset of affected users to still experience impact after the problematic code was disabled. They have addressed the misconfiguration and are working with a subset of affected users to validate that our actions successfully remediated impact while they continue development of a long-term fix to remediate impact for all affected users.

Scope of impact: Microsoft Teams meeting participants attempting to view meeting notes that were added after meeting creation may be impacted.

Root cause: A deployment to introduce a new calendar form contained a code issue, causing the impact.
