My Template has disappeared again from my Ribbon Bar on my Outllok

Question

I need to retrieve my templates as I use them everyday, This has happened 3 times this week

Answer 1

Hello Anita,

This usually happens because the Outlook “My Templates” add-in is being disabled or unloaded. The quickest way to bring it back is to check under Outlook’s Home tab > Get Add-ins (or Manage Add-ins) and confirm that “My Templates” is installed and enabled. If it’s missing, re‑enable it from there. If it keeps disappearing, it’s often due to Outlook running in “slow add‑in” mode, where it automatically disables add‑ins that it thinks are affecting performance. You can verify this under File > Options > Add-ins > COM Add-ins and re‑check the box for “My Templates.”

To stop it from dropping repeatedly, make sure you’re on the latest Outlook build, since Microsoft has patched stability issues with this add-in in recent updates. If your organization manages add-ins centrally, you may need your admin to push the add-in back through Exchange or Microsoft 365 admin center. In short, re‑enable the add-in, update Outlook, and if it keeps happening, escalate to IT so they can enforce the add-in at the tenant level.

The disappearing My Templates button in Outlook is a known service issue with the My Templates add-in and other add-ins such as Viva Insights and Salesforce.

When this happens, the View Templates button is missing from the ribbon, and My Templates is also missing under All Apps / More Apps. Attempts to re-add it can show a "Something went wrong" error or it may not appear in Add Apps search. This is being tracked as service incidents (EX1238375 and MO1243496) related to recent authentication changes for add-ins in Exchange Online.

Because this is a service-side problem, the primary remediation is handled by Microsoft as the fix is deployed. If the issue persists in a tenant, an admin can verify and enable the add-in at the organization level using Exchange Online PowerShell:

1. Connect to Exchange Online PowerShell as a tenant administrator. See Connect to Exchange Online PowerShell.
2. (Optional, if requested by support) Start a transcript to capture output:

      Start-Transcript -Path "C:\mytemplates\MySession.txt" -Append
   

3. Check the status of the My Templates add-in:

      get-app -Identity a216ceed-7791-4635-a752-5a4ac0a5eb93
   

4. Ensure it is enabled for the organization:

      Set-App -Identity a216ceed-7791-4635-a752-5a4ac0a5eb93 -OrganizationApp -Enabled $true
   

5. List add-ins to confirm status:

      get-app
   

If the add-in is enabled but still intermittently disappears, this aligns with the ongoing service incident and will typically resolve as Microsoft completes deployment of the fix. For persistent impact, open a support case with Microsoft 365 support and provide any requested traces (for example, a HAR/performance trace captured as described in the article) and the PowerShell output above.
