Hi @Mack Isgro,
Welcome to Microsoft Q&A forum.
Thank you for contacting us regarding the issue with the My Templates feature in Classic Outlook for Windows.
After reviewing the situation, I've found this is part of an active Microsoft service incident (EX1183224) that Microsoft has confirmed. Part of the infrastructure handling mailbox connectivity is currently underperforming, which may cause some users to experience difficulties accessing the My Templates option in Exchange Online.
For your reference: Service health - Microsoft 365 admin center
Note: Access is limited to Microsoft 365 Global Administrator. Please contact your IT admin if you don’t have access.
The next update is scheduled for November 22, 2025. Service availability is gradually returning to normal. In the meantime, you might consider using Signatures as a temporary workaround. Please note that as a forum moderator, my testing environment is limited, and I don’t have access to Microsoft’s internal systems to investigate the root cause.
For now, no action is needed on your side. Once the systems are fully restored, Outlook should return to normal without requiring any changes to your settings or devices. We appreciate your patience as the engineering teams work to deliver the best possible experience for all users.
Additionally, some users have resolved similar issues by repairing their Office installation via the Control Panel. If the problem persists, this could be worth trying.
