Outlook Offline Phase I: Available Features

Updated November 18, 2025.

The following are some of the key features introduced in Outlook Offline Phase I:

• Offline Email Access: Users can read, reply to, and compose new emails offline. These actions will be synchronized once the user reconnects to the Internet.
• Calendar Management: Users can create, edit, and delete calendar events while offline..
• Contact Access: Access to contacts is available offline, allowing users to look up contact information.
• Synchronization: Any offline changes, such as sending emails, updating calendar events, or modifying contact information, will automatically synchronize once the internet connection is restored.

Unsupported Features

While Outlook Offline Phase I brings a host of new functionalities, it is important to note that not all features are supported in the offline mode - yet. I recommend downloading the updated list of supported and unsupported features to ensure you have the most up-to-date information on what is supported and what is not.
