Outlook: 1-year and 2-year options for email sync window (Offline settings)

Microsoft 365 Message Center Archive by Merill Fernando

Summary

In the new Outlook for Windows, users can choose to save 1 year or 2 years of email on their device for offline access. This expands the existing offline settings and allows users to access more email when they are not connected to the internet. The new options are available under Settings > General > Offline > Days of email to save, giving users greater flexibility based on their storage and offline needs."
