The Outlook add-in operates while Outlook is open, and rules and automations run during that time. The desktop app runs persistently in the background — so automations fire consistently, even when Outlook isn’t actively in use.
For organizations that need complete email capture without depending on user behavior, the desktop app provides more reliable coverage.
When a user saves an email to SharePoint, all team members can see that it was saved and exactly where. No more duplicate saves, no more “did anyone file this?”
Ask in plain language and get the right file, email, or content — faster.
The desktop app deploys centrally via Microsoft Intune. Your existing harmon.ie configuration applies. Updates are automatic.
