Issue Status: RESOLVED
Issue Description: Some users may experience inconsistent behavior with the ‘Track email and document open rates’ feature.
More info: Affected users may see error messages or the ‘Track email and document open rates’ feature in the Viva Insights Add-in for Outlook not appearing despite meeting the criteria of having at least five recipients and being sent from a user mailbox hosted on Exchange Online with a valid service plan. This feature is available to users with the MyAnalytics (Full) service plan included in Office 365 E5.
Final Update: 02/07/2025 11:00:00 AM – Microsoft have received feedback from some affected users confirming that impact has been remediated.
Scope of impact: Impact is specific to some users with the MyAnalytics (Full) service plan included in Office 365 E5 who are served through the affected infrastructure.
Root cause: A recent service update, intended to change license checking logic, inadvertently introduced a code regression that’s resulting in impact.
