If the Outlook add-in is not appearing in the Outlook mobile app, even though it has been deployed, you may need to update the manifest file used to deploy the add-in via the Microsoft 365 Admin Center.
We periodically update this manifest file, which is available at https://seas2.fieldeffect.net/plugin.xml. When we make an update that requires user action, we will make an announcement via the MDR Portal or other means.
If you are experiencing this issue, update the manifest file in the Admin Center to the latest version. If the SEAS Outlook Add-in has been previously deployed, uninstall it before re-deploying.
To learn how to update the manifest file, see Installing SEAS: Update the Add-in.
