This tutorial will show you how to turn on or off work offline in the Outlook for Windows app for your account in Windows 10 and Windows 11.
The new Outlook for Windows brings the latest features, intelligent assisted capabilities and a new modern and simplified design to your Outlook app. You can tailor it to your style and do more with new Outlook for Windows.
In Outlook, you have the flexibility to make Outlook work online or offline with your mail server.
You can use the new Outlook for Windows even when you’re not connected to the internet by enabling offline access. When turned on, the new Outlook for Windows saves a copy of your emails, calendar events, and people (previously contacts) to your device, providing access to these items when you're offline and improved performance when you're online.
Your offline settings determine which items are saved to your device and for how long. When you’re back online, new Outlook for Windows automatically updates the items that were saved to your device.
If you try to do something that’s not available offline, you'll get an error message, or the changes you made will revert back to what was previously saved.
Most actions you perform online are also available when you’re offline. These include, but aren’t limited to:
Read, manage, and view Outlook items:
- Read emails
- Create and save new email drafts
- Send new messages to Outbox
- Rename folders
- View your calendars and events
- View your people (previously contacts)
- Archive
- Categorize
- Delete
- Flag / Unflag Ignore
- Mark as Read / Unread
- Move to Focused / Other
- Move to folder
- Pin
- Report Junk / Not Junk
- Report Phishing
- Snooze
- About Outlook
- Automatic replies
- Categories
- Email accounts
- People view
