How to use Outlook’s working offline mode

Do you use the Outlook desktop application? If so, you can also work with your email program offline. We’ll explain the basics as well as how you can activate and deactivate Outlook’s offline mode.

How to work with Outlook’s offline mode

Outlook’s offline mode enables you to conveniently use your email program even if you’re not connected to the internet. If you lose your internet connection (for example, when working on your laptop on an aeroplane), Outlook will show you an error message in standard mode. You can stop these kinds of messages by switching to Outlook’s offline mode.

How to find the cause of the Outlook ‘Disconnected’ status

If Outlook displays the ‘Disconnected’ status, it means your email program is unable to connect to the online email server.

Follow the steps below to identify the cause of the error:

  1. First, check whether your computer is connected to the internet. One way to do this is by attempting to access a web page in your browser.
  2. If you’ve determined that your internet connection is working properly, you should then check whether you can send and receive emails in Outlook.
  3. If Outlook displays the status ‘Disconnected’ even though you’re able to send and receive emails without any issues, your computer might need to be updated. Check to see if your operating system has new updates available.
  4. If your software is already up to date, there’s probably an issue with your account settings.

If the Outlook account settings are causing the problem, you can try to resolve this by removing your Outlook account and then adding the Outlook account again.
