Due to Virtru's compliance with FedRAMP, Virtru plugin activations expire every 120 days. After any expiration, the plugin will prompt a user to re-activate in the Compose email window. There are also a few cases where users might be prompted to activate sooner than 120 days:
- If the user clears their browser cache
- If Virtru is uninstalled
- If an already activated user attempts to use Virtru on a new device
Furthermore, if a user receives delegated access to another user's mailbox, the delegatee will be prompted to reactivate every 10 days.
