Outlook for Windows: How to Enable or Disable Offline Mode
Offline mode in Outlook for Windows lets you read, write, and sort your emails without an active internet connection by saving copies of your messages right on your computer. This handy feature keeps you working during travel or when your Wi-Fi drops out.
To enable or disable Offline Mode in Outlook for Windows, go to Settings (gear icon) > General Offline. Use the toggle switch to turn offline email, calendar, and people on or off, then select folders and days of data to save.
The newer Outlook app, which replaced the old Mail and Calendar apps in Windows 11 starting in late 2023, manages these offline files automatically. Turning this setting on or off takes just a few clicks, and shutting it off saves hard drive space if you never work away from the internet.

Outlook configures communication to work online or offline with the mail server. Enabling offline access lets the new Outlook for Windows operate without an active internet connection.
Enabling this feature saves a local copy of emails, calendar events, and contacts. Accessing items offline becomes possible while potentially improving performance when online.
Turn on or off Offline mode in Outlook for Windows
Open the Outlook app through the Start menu or the taskbar search box to get started.
Locate and click the Settings gear icon positioned at the top right of the menu bar.
Select General from the left sidebar, then click Offline.
Toggle the switch next to "Enable offline email, calendar, and people" to the On or Off position.
Enabling offline access unlocks options to specify which folders save locally and how many days' worth of emails store on the computer.
Click the Save button to confirm these changes.
