About

The Virtru for Outlook 365 add-in can be used both with personal accounts and within delegated and shared mailboxes. However, there are a few prerequisites for use in both scenarios. This article will walk through prerequisites and the activation process.

Prerequisites

Platform

For full compatibility, users will need to access their primary and shared/delegated mailboxes from Outlook Desktop. Due to recent Microsoft updates, the add-in is not compatible within OWA.

Delegated access to another user's mailbox

When a user has delegated access to another user's mailbox, they typically cannot manage add-in installations. So, if the add-in has not already been installed on the account, the delegatee will not be able to add and use Virtru.

In order to use Virtru in the delegated mailbox, the add-in must be installed by the mailbox owner or deployed by an admin.

Access to a shared mailbox

In order to use Virtru in a shared mailbox, the add-in must be deployed by an admin.

When a user has access to a shared mailbox, they typically cannot manage add-in installations. So, if the add-in has not been deployed to the account, the end-user will not be able to add and use Virtru.

Additionally, the organization's add-in manifest must be on version 1.17.0 or above. Details on checking and updating the manifest can be found here: 1.17.0 Release - Update required for Shared Mailbox support

Activation Process

In order to complete a delegated or shared mailbox activation, users will first need to activate Virtru with their primary mailbox within the same instance of Outlook Desktop.

Once their primary mailbox is activated, users can then activate the shared or delegated mailbox. During this step, they may need to select the primary account associated with the shared/delegated mailbox. Users will then Activate with Email.
