Latest Message<\/th>\nTitle: Some users may be unable to access the My Templates and Viva Insights Outlook add-ins in Exchange Online<\/p>\n

User impact: Users may be unable to access the My Templates and Viva Insights Outlook add-ins in Exchange Online.<\/p>\n

Current status: We’ve identified that the affected add-ins should be available to affected users, according to the HAR logs, but we haven’t yet identified why the remaining users still don’t have access. We’re continuing our investigation of the HAR logs to determine why our previous fix didn’t remediate impact for all users as expected.<\/p>\n

Scope of impact: The problem impacts some users trying to access the My Templates and Viva Insights Outlook add-ins in Exchange Online. This section may be updated as our investigation progresses.<\/p>\n

Root cause: A recent change to the Admin API is causing a mismatch in the data format of users’ mailbox cache, and is resulting in the missing Outlook add-ins.<\/p>\n
