The primedocs signatures can also be used in the Outlook Mobile app with the primedocs AddIn:

Installation
Configure primedocs.config
The Outlook AddIn must be configured at primedocs.config
Any GUID can be used as the id.
<primedocs>
...
<outlookAddin id="[GUID]" namePrefix="" />
</primedocs>
The namePrefix can be used if there are several environments. The AddIns are then named in the form {namePrefix} primedocs.
After changing the primedocs.config, the web applications should be restarted.
Generate Manifest
You can then generate the Outlook Addin Manifest via a link:

The generated manifest can then be uploaded and distributed via Microsoft 365 Administration.

The rollout of the app may take some time.
The distribution and access management of the app is carried out exclusively by Microsoft Administration.
