How to fix Outlook Working Offline ? (7 Simple Steps)

Outlook is a popular email client that allows users to manage their email, calendar, contacts, and tasks all in one place.

However, sometimes Outlook may switch to “Working Offline” mode, which may prevent users from sending or receiving email.

This can be frustrating and confusing, especially if you rely on Outlook for your daily communication needs.

In this article, we’ll discuss the reasons why Outlook may switch to “Working Offline” mode and provide some troubleshooting tips to help you get back online.

Why is Outlook working offline ?

There are multiple potential causes for why Outlook may be operating in offline mode.

Some of the most common reasons include issues with the internet connection, problems with the Outlook program itself, or a user manually selecting the “Work Offline” option.

Your internet connection is down: This is the most obvious reason why Outlook is working offline. If you can’t connect to the Internet, Outlook won’t be able to sync with your email server.

Your email settings are incorrect: If your email settings are incorrect, Outlook will not be able to connect to your email server. This could be due to a typo in your email address or password, or it could be a problem with your email server’s configuration.

A third-party add-in is causing problems: Sometimes, third-party add-ins can interfere with Outlook and cause it to work offline. If you recently installed a new add-in, try disabling it to see if that fixes the problem.

Corrupt outlook profile: One way to solve the problem you’re experiencing is to create a new Outlook profile. This can often help resolve issues and restore functionality

Open Outlook in safe mode

Starting Outlook in Safe Mode may resolve the “Outlook is working offline” problem by disabling add-ins and other add-on programs that may be interfering with Outlook’s ability to connect to the Internet.

Here are the steps to launch Outlook in safe mode:

  • Close Outlook.
  • To start Outlook in safe mode using your keyboard, press the “Windows” key and the “R” key at the same time.
  • Type outlook/safe and press Enter.
  • Outlook will start in Safe Mode.

  • To exit Safe Mode, close Outlook and restart it normally.

Recreate OST file

If the OST file is corrupted or damaged, rebuilding the OST file may resolve the “Outlook is working offline” issue. An OST file is a cached copy of your mailbox that Outlook uses to work offline. If the OST file is corrupted or damaged, Outlook will be unable to connect to your mailbox and will work offline.

To recreate the OST file, follow these steps:

  • Close Outlook.
  • Find the location of your OST file. The default location is %appdata%\Microsoft\Outlook\.
  • Rename OST file. For example, you can rename it to OST.old.
  • Restart Outlook. Outlook will generate a new OST file.
  • Try sending and receiving email. If Outlook is able to connect to the Internet and send and receive email, the problem is resolved.

Manually Setup Exchange Server Account

If the automatic setup process isn’t working properly, manually setting up the Exchange Server account in Outlook may resolve the “Outlook is working offline” issue.

The automated setup process uses information from your email provider to configure Outlook, but if this information is incorrect or incomplete, Outlook will not be able to connect to your Exchange Server account.

To manually set up an Exchange Server account in Outlook, follow these steps:

  • Open Outlook.
  • Click on File Tab.
  • Select Account Settings.
  • Click on the Add button.
  • Select the option that allows you to manually enter server settings or choose other server types that are not automatically detected.
  • Select Exchange.
  • Enter your email address and password.
  • Select the type of Exchange server you are using.
  • Click on the Next button.
  • To complete the setup process, simply follow the instructions that are displayed on your screen.

Once the setup process is complete, Outlook will attempt to connect to your Exchange Server account. If the connection is successful, Outlook will no longer work offline.

How to fix missing “Work offline” button ?

The “Work Offline” button in Outlook allows you to access your email and work with messages when you’re not connected to the Internet. This button may be missing for some reason.

First, Outlook may not recognize your email provider as compatible with Microsoft Exchange. In this case, the “Work offline” option won’t appear at all.

However, even if your email provider is compatible, the button may be missing due to a configuration issue. To fix this:

  • Firstly, access account settings in Outlook, open the program, go to File > Account Settings > Account Settings
  • Secondly, click the “More Settings” button and select the “Advanced” tab.
  • Thirdly, check the boxes for “Use Cached Exchange Mode” and “Download shared folders”.
  • Next, uncheck and re-check the “Use Cached Exchange Mode” box.
  • Then, click OK and close all Settings windows.
  • Finally, restart Outlook.

The “Work Offline” button should now appear on the Send/Receive tab, allowing you to access your email when you’re offline.

Checking the “Use Cached Exchange Mode” box ensures that Outlook will download and store your email messages locally, making them available even when not connected to the Internet.
