Tresorit offers two different types of add-ins for Outlook: our Outlook desktop add-in for Windows and the newer M365 Outlook add-in. This article is about the Windows Outlook add-in.

💡 Did you know? If you set up policies for link creation (such as expiry dates, mandatory passwords, etc.), these will also apply to the documents shared through both of our Outlook add-ins.
