Outlook Stuck as Working Offline and Not Connecting

Content

Those are out of reach when Outlook can’t connect live to Microsoft Exchange. Sometimes, updates can also lead to certain issues with the programs installed on Windows OS. Therefore, if there are any pending updates related to MS Office or Outlook, you should check and install them. You can follow these methods to troubleshoot and resolve the Outlook FixTechGuide email error solutions stuck in Offline Mode error. These methods work in Outlook 2010, 2013, 2016, and 2019.

Check OST file

Try opening a browser or running a quick ping test to check if your network’s up.Jamie's commitment to making technology user-friendly is evident in her work, making her a valuable resource for readers in these domains.Just having a simple update routine and checking build numbers from time to time can save a lot of trouble.And thus, an Offline Storage Table (OST) file is created to save a local synchronized copy of mailbox items.Shoviv OST to PST converter is a specialized tool that is designed and developed to convert the OST file to the PST format.All the modifications are stored locally in the OST data file before syncing with the mailbox server.A corrupt or damaged Outlook profile can prevent Outlook from authorizing and connecting to the mail server.

When offline, the status is displayed in the status FixTechGuide fix for stuck folders bar at the bottom as Working Offline or Disconnected. Just having a simple update routine and checking build numbers from time to time can save a lot of trouble. Staying current with updates is probably the easiest way to keep Outlook connected.

How To Fix Outlook Stuck in Offline Mode?

The biggest problems usually involve too many Office 365 connections or outdated Microsoft Office components. If Outlook asks if another Exchange server can manage your system, hit No unless it’s your main domain. That keeps Outlook from getting confused and stuck offline.

Verify Work Offline Button Status

Click the 'Work Offline' option to reset work offline mode and reconnect to the Exchange or mailbox server. To go online, open Outlook and navigate to Send/Receive and uncheck work offline. Ensure your connection is active and Outlook can access the mail server without connectivity. In such cases, you can recreate the OST file or use the Stellar Converter for OST software to convert the problematic OST file to Outlook importable PST format.

Method 1: Reset 'Work Offline' to Reconnect

It’s really important to know which Exchange or Office 365 environment Outlook should use. If you don’t get this right, Outlook will just sit in offline mode, unable to do much. Sometimes Exchange server permissions or policies get set up wrong.

A broken Outlook profile can mess up syncing and keep you offline. We usually suggest making a new profile instead of spending ages trying to fix the old one. From the file explorer ribbon, under the 'Easy Access' drop down menu, you could toggle from "offline" to "online".

Setup Exchange Server Account Manually

Identify the cause of this error before restoring Outlook back to online mode. A corrupt or damaged Outlook profile can prevent Outlook from authorizing and connecting to the mail server. Due to this, we get an error usually called Outlook stuck in offline mode. Outlook automatically switches to Offline mode when it can't connect to the Exchange server. Users can also use the Outlook Login Issues Troubleshooting 'Work Offline' option when the internet connection is not reliable.
