Frequently Asked Questions

Why is the 'Try the new Outlook' toggle completely missing on my computer?

The toggle may be missing due to outdated Microsoft 365 installations, incompatible Microsoft Exchange Server environments, specific account configurations, or strict organizational IT policies that intentionally disable the feature.

Will I lose my emails if I switch from Classic to New Outlook?

No, your emails, contacts, and calendar events are safely stored on the mail server. Switching to the New Outlook merely changes the user interface you use to access and manage them.

How do I switch back to Classic Outlook if I don't like the new version?

In the New Outlook interface, look for the 'New Outlook' toggle in the upper-right corner and switch it to the 'Off' position. The app will close and automatically reopen using the Classic Outlook interface.

Does the New Outlook support all Microsoft Exchange Server accounts?

While it supports modern Exchange setups and most Microsoft 365 accounts, some older or specific on-premises Microsoft Exchange Server environments are not fully supported yet, which is often why the toggle is hidden.
