Notes
This procedure applies only to Outlook Web and Outlook New users. If you are using Outlook Classic (legacy version) , do not deploy this version of Secure Exchanges. Instead, follow the installation procedure for Outlook Classic.
Info
The installation must be performed by your organization's Microsoft 365 administrator. This person will need to follow Procedure 1. If there is no administrator (e.g., individual account), proceed directly to Procedure 2.

Procedure 1 – Deployment by a Microsoft 365 administrator

  6. Click Next , then choose the deployment scope:
    1. For you only

  7. Click on " Accept permissions", then accept the necessary permissions:


  8. Finalize the deployment by clicking on "Complete Deployment"


Once the deployment is complete, Secure Exchanges will appear in the Add-ins section of the admin portal. Once the deployment is complete, Secure Exchanges will appear in the Built-in apps section visible in your Microsoft Admin Center. To choose the deployment method that best suits your organization, click "Add-ins," and then click Secure Exchanges.


This is the page where you can choose the deployment method best suited to your organization:
  1. Resolved (default): the module is automatically added to Outlook and cannot be removed (recommended).
  2. Available: Users can install the module themselves from Get more add-ons.
  3. Optional: The module is added automatically, but users can remove it.

We recommend the "Resolved " option, as it ensures that Secure Exchanges remains visible and functional for all affected users.
