Plugin management

Two components are available to manage attachments via the Outlook email client.

• The Oodrive Work add-in, compatible with the most recent version of the Outlook client and available for Web, Windows and Mac environments.

• The PostFiles plugin, compatible with older versions of the Outlook client and available for Windows only.

These components take over from the standard attachment system and generate a secure sharing link, with all the security and tracking options specific to the Oodrive Work solution.

Oodrive Work add-in

Deployment

Oodrive puts at your disposal a manifest file in XML format. This manifest contains all the information needed to integrate the add-in into Outlook (such as the service URL, required permissions and the add-in's user interface).

The Office 365 administrator must:

1. Sign in to the Microsoft 365 Admin Center.

2. Import the XML manifest file via add-ins management (either in the Exchange Admin Center, or directly via the “Integrated apps” section).

3. Choose the deployment method (to all users, to specific groups or to certain users).

4. Define whether the add-in is mandatory or optional.

5. Validate deployment so that the add-in is automatically available in Outlook for all targeted users.

For more information about the deployment of add-ins in Microsoft, please refer to: Deploy add-ins in the Microsoft 365 admin center.

PostFiles plugin

Deployment

For more information about the deployment of the PostFiles plugin, please refer to the dedicated guide: PostFiles Outlook Administration.
