Here’s a question we just got from one of our readers:

Hey there 🙂 I have Outlook 365 installed on my computer which is quite an upgrade from my previous email client. But here’s the thing: Every once and then when i start Outlook on my laptop (which is typically connected to the network via Wifi,) it shows that Outlook is disconnected from the server and i am not really able to receive emails. Any ideas about how to fix this so i can reconnect to my server?

1. Using Windows 10 64 bit, CONSTANTLY, i. Automatically updated, using Outlook 2016 (Office 365 subscription) with your own service's Exchange server - so no idewa whiah version this is. I have uninstalled Outlook, reinstalled, with no change whatsoever.
2. Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010, Outlook for Office 365; In this article. Original KB number: 3134780. Microsoft Outlook cannot connect to your Microsoft Exchange mailbox, and the connection status is displayed as Disconnected.
3. Microsoft fully supports Office 2016, Office 2019 and Microsoft 365 for Mac on 10.14 Mojave when you have the following Office updates installed: Microsoft 365/2019 - Build 16.17.0 or later. Office 2016 - Build 16.16.2 or later. Skype for Business 16.21.65 or later. For the best experience with 10.14 Mojave, be sure to keep your Office apps up.
4. Most of the times, Microsoft Office folks release updates that can handle this problem and other Outlook issues. Before you attempt at troubleshooting this issue, you may first want to update the latest Outlook install on your Mac running Catalina. On the Top menu of Outlook, Click on Help Check for Updates.

Thanks for the questions. In my answer i will assume that you are on Windows and not on macOS.

We’ll look into two possible scenarios:

1. Your Outlook client is working in the so-called offline mode, and can’t connect to your mail server.
2. Your Outlook client is online, but for some reason it is disconnected from the server so it can’t refresh your mailbox.

Outlook is working offline

When Outlook is working in offline mode, that will be clearly indicated in the status bar in the bottom of your screen, as shown below.

You might as well notice that your Outlook icon in the Windows bar has a red X sign indicating you are not online.

Offline access to Outlook might be beneficial if you are traveling or would like to access your mailbox from places with no reliable network connectivity. That said, when online, you most probably would like to connect to the mail server and start sending and receiving your emails.

So how to go back online? Just proceed as following:

1. Open Microsoft Outlook.
2. Then navigate to the Send / Receive tab.
3. In your right hand side, you’ll notice the Work Offline button as shown below.

4. Hit that button
5. Outlook will attempt to re-connect. If for some reason that doesn’t happen, go ahead and restart your Outlook client.

Outlook is disconnected

You might find out that your Outlook has been disconnected from the server. That will be visible in the status bar in the bottom of the screen as shown below.

This is probably due to a temporary hiccup in your connectivity to the network/VPN. When back online, Outlook might automatically try to re-connect back to the server. If this doesn’t work, here is how to easily reconnect.

Goo chances that if you are using Exchange, Outlook will first display the “Need Password” message. If so:

1. Go to the Send / Receive tab.
2. Hit the Type your Exchange Password button and proceed accordingly.
3. If Outlook connects and starts to sync your mailbox you are all set.
4. If that’s not the case or you are not working on Exchange, close all Outlook Windows.
5. Restart Outlook.
6. If can’t connect you might want to ensure your Network/Internet connectivity is available. You can easily do that by opening a browser window and opening a website.
7. If no Internet issues, try to restart your computer.

If still disconnected, we’ll go ahead and open Outlook in the so-called safe mode:

1. Close all Outlook Windows.
2. Assuming you are on Windows 10, from your Desktop, hit the Search Magnifying glass (Next to the Start icon in the left hand side of the desktop.
3. Then type Run and open the Run Desktop App.
4. Then type Outlook /safe and hit OK.
5. Outlook will now open in safe mode.
6. Now try to connect.
7. Disable any Outlook add-ins and restart Outlook.

Then type

Symptoms

Microsoft Outlook 2016 for Mac crashes immediately after startup. The crash reporter displays the following error information.

Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000002, 0x0000000000000000Application Specific Information:

dyld: launch, loading dependent librariesDyld Error Message:
Library not loaded: @rpath/osfcore.framework/Versions/A/osfcore

Referenced from: /Applications/Microsoft Outlook.app/Contents/MacOS/Microsoft Outlook
Reason:image not found

Cause

This problem occurs if the underlying file system is formatted as case-sensitive. In this scenario, the file is named OsfCore.framework. However, Outlook 2016 for Mac looks for a file that is named osfcore.framework and cannot find the file inside the app bundle.

Workaround

To work around this problem, rename the OsfCore.framework file as osfcore.framework. To do this, follow these steps:

1. In Finder, open the Application folder.
2. Right-click Microsoft Outlook, and then select Show Package Contents.
3. Open the Frameworks folder, and then find the OsfCore.framework file.
4. Select OsfCore.framework, press Return, and then change the file name to osfcore.framework.

More information

You can use Disk Utility to determine whether the file system is formatted as case-sensitive. To do this, run Disk Utility, select the hard disk drive partition, and then select the Erase tab to view the Format option that's selected. If either of the case-sensitive options are selected, you may experience this problem.
