One of the major advantages of the Microsoft Add-in is that the deployment on your collaborators' accounts is done automatically thanks to the simultaneous deployment.
Please consult the prerequisites before installing the Add-in.
Log into the Microsoft 365 Administration Center, make sure you have the Global Administrator role to be able to deploy.
On the left-hand drop-down menu go to : Settings > Integrated applications
If you can't find 'Settings' press 'Show all'.
Then you need to click on the 'Upload custom apps' button
Load the manifest file with this link: https://nadine.signitic.app/manifest.prod.xml
Several options are available to you:
Entire organization - If you choose this option, you must have a signature configured in the Signitic application (Admin) for each user of your organization. Warning: Please note that users who are not active on Signitic but who have the Add-in installed, will no longer have an Outlook signature by default.
Specific users/groups - Recommended for your trial period - With this option, you control exactly who will have the Add-in deployed. This allows you to deploy to a specific part of your organization and perform testing.
Check the option that suits you then click 'Next'.
Finally, finish the deployment. Once Microsoft has completed the deployment, you will receive a confirmation email. Deployment can take up to 72 hours.
