How To Fix Outlook Stuck in Offline Mode?

Are you experiencing the problem of 'Outlook stuck in offline mode' and looking for a comprehensive solution? If so, you have landed at the right place.

What is the Offline and Online Mode in Outlook?

As is known, we can switch from Offline to Online Mode and vice versa in Microsoft Outlook 2010 and later versions. Once Outlook is configured with an Exchange account, the Cached Exchange Mode is enabled automatically. And thus, an Offline Storage Table (OST) file is created to save a local synchronized copy of mailbox items.

However, when Outlook cannot connect to the Exchange server, it automatically switches to Offline mode. All the modifications are stored locally in the OST data file before syncing with the mailbox server. Users can also utilize the 'Work Offline' option when there is an unreliable internet connection. This allows them to work without interruptions.

When you are offline, at the bottom of the status bar, it displays 'Working Offline' or 'Disconnected.' Moreover, when Outlook is in this mode, users cannot send or receive emails.

To keep the workflow smooth, you must ensure that your Outlook is not stuck  in offline mode and you can send/receive emails without any problem. This guide highlights why one is getting the 'outlook 365 stuck in offline mode' error so frequently.

Part 1: Symptoms of Outlook Stuck in Offline Mode

Working Offline Status

Working offline is usually an option. It is simple to return to an online work mode.

Select Work Offline from the Send/Receive tab in Outlook to reconnect.

  • If the Work Offline button background is shaded (as shown in the image above), it reflects that you are not connected. However, if the background is transparent, you are linked.
  • Cached Exchange Mode may be turned off when you cannot see the Work Offline button. Also, when your email account is a Microsoft Exchange Server or a Microsoft 365 account. To change that setting, follow the Turn on Cached Exchange Mode steps. Alternatively, contact the person in charge of your organization's Exchange server.

When using a Microsoft 365 account, we recommend that Cached Exchange Mode be enabled at all times.

Disconnected Status

There could be several reasons for your Outlook disconnect. Given below are just a few examples of possible reasons.

  • If your Internet connection is operational, there could be an issue with the mail server.
  • If you can access your email through a website like http://outlook.com, see if you can receive and send an email that way. If your email isn't working on the website, contact your email service provider's technical support.
  • If you can send or receive emails from the website, your mail server is working correctly. However, your computer may require updates, or there may be an issue with your account settings.

Part 2: Why Does Outlook Stuck in Offline Mode?

You must now understand that you cannot send or receive emails when Outlook is offline. Therefore, it becomes essential to understand the underlying causes of this problem to fix them permanently.

  • Problem with the mail server: When there is a problem with the mail server, the user encounters this problem. Log in to your account if you want to double-check. Check to see if you can send and receive emails. If you are not receiving it, the mail server may be to blame; contact the administrator.
  • Internet Connectivity Issues: Outlook may display an Offline working mode or a 'Disconnected' message if there is an issue with internet connectivity. The outlook may be unavailable for a short time or remain disconnected until the connection is restored.
  • Issues with the configuration: If you cannot transfer emails and are experiencing disconnection issues, check your account's configuration settings.
  • Issues with the Outlook profile: An Outlook profile that is corrupted or damaged can prevent Outlook from delegating and connecting to the mail server. As a result, we get an error known as Outlook stuck in offline mode.

Step 2: Press the Windows+R keys simultaneously, then type Outlook.exe /safe and press the 'Enter' key.

This will launch Outlook in a secure mode.

6.    Recreate OST File

The Outlook OST file might have an issue prohibiting Outlook from connecting to and syncing mailbox items with the mailbox server if the techniques outlined above do not resolve the issue. In these circumstances, you have two options: recreate the problematic OST file from scratch or use the Stellar Converter for OST software to convert it to an Outlook importable PST format.

How to create a new OST file:

Step 1: Click File > Account Settings > Account Settings, then click "Data Files" in Outlook.

Step 2: To open a file location, choose the Outlook profile and click it.

Step 4: Restart Outlook after deleting the OST file.

This will fix the Outlook stuck in offline mode problem and build a fresh OST file. Additionally, it will sync every piece of server-based mail.

The Outlook may fail in recreating the OST file. This happens in the case when it is not getting connected to the server and mailbox. Some of the instances that reflect this situation are having problems with the profile on the mailbox server, disabled or deleted mailbox, etc. It would be best to repair the damaged or corrupted OST files first in such situations. This will help you repair damaged/corrupted files and restore emails deleted long ago.
