As we mentioned in contentACCESS documentation, Mail app is a contentACCESS feature that was designed to allow the user to manually archive/restore from/to mailboxes directly in Outlook, without any need to use an email archive job.
The following platforms support Mail app:
- Desktop (Windows, Macintosh – on Macintosh MS Outlook 2015+ is required)
- OWA (desktop computer, android, iOS, phone, tablet)
- Native MS Outlook app on tablets
Native Outlook app on mobiles doesn’t support Mail app.
