Outlook 365 "My Templates" missing

Here is the URL for anyone wondering:
Message center - Microsoft 365 admin center

I followed the steps included in the message:

Sign in to the [Microsoft 365 Apps admin center](https://config.office.com/ "config.office.com"). If you're using the admin center for the first time, review the terms. Then, select Accept.

1. Under Customization, select Policy Management.
2. On the Policy configurations page, select Create.
3. On the Start with the basics page, enter a name (required) and a description (optional), then select Next.
4. On the Choose the scope page, determine whether the policy configuration applies to all users, specific groups, or to users who anonymously access documents using Office for the web.
5. If the policy configuration applies to specific groups, you can now add multiple groups to a single policy configuration for more flexible targeting. To add groups, select Add Groups and choose the relevant groups. Adding multiple groups to a single policy configuration allows for the same group to be included in multiple policy configurations, facilitating a more streamlined and efficient policy management process.
6. After making your selection, choose Next.
7. On the Configure Settings page, select the “Allow the use of additional optional connected experiences in Office” policy. In the Configuration Setting dropdown, select either enabled or disabled.
8. After making your selections, select Next to review your selections. Then select Create to create the policy configuration.

Apparently, it could take ~24-48 hours before changes apply. I will share if the above resolved our issue or not.

Our issue is that the "My Templates" button disappeared from Outlook (classic) for myself (IT Tech) and my end users. The My Templates button is only present now on the new Outlook app (which is objectively worse than Outlook (classic)).

The solution for our organization was posted above: See this thread: Teams missing GIF option in messaging | Microsoft Community Hub

The issue was that Microsoft changed a setting for all GCC customers O365 tenants. If an admin changes Optional Connected Experiences (OCE) back to Enabled, both My Templates and Teams GIFs should return within a day or so.

Hello, we are using the new Exchange Admin Center. There is no option for the classic admin center in the bottom left corner of the new EAC home page, or any page. I also have access to 365 admin center. When going to Settings > Integrated apps, there is no My Templates app, there are 26 3rd party add-ins visible, but none of these are what was previously built into Outlook. There are no incidents related to this in the Service Health Dashboard.

The only option under Organization is "shared" when looking in the Exchange Admin Center. This is for me and other admin users with higher privileges.

Having the same issue here, hopefully this gets resolved quickly.
