To fix Office 365 “No internet connection”, you need to run these 2 commands and reset Winsock. (IP configuration /flush DNS and Winsock reset). Let’s take a detailed look at how to fix the Office application internet connection error if you are trying to open Office and encounter the 365 no internet connection error.
In this Techquack article, we will discuss different ways to fix Office 365 “no internet connection” error.
What causes the “No internet connection” error in Office 365 on Windows 10
In spite of the fact that you can still use the app without an Internet connection, some features will not work if your connection isn’t active. Although you can still use it and do what you want, you will be unable to access the error message. In the case of OneDrive syncing, for example, the error message will prevent your files from automatically syncing to the cloud.
Outlook We Are Unable To Connect Right Now
However, this is a Windows problem, despite the fact that this error appears in Office. A misconfigured VPN, an incorrectly blocked or intercepted web proxy, or restricted location awareness settings could cause Windows to think it has “Limited Internet” or “No Internet.”
As it turns out, there are several possible reasons why this error message appears, so let’s explore them in more detail below.
Outlook Is Not Connecting To Server
Steps for connecting to the Microsoft Exchange server using SSL are as follows:
Third-party VPN: It turns out that the most obvious cause of the error message is a third-party VPN. In some cases, the VPN you installed and MS Office are not working properly, preventing Office from establishing an internet connection with its servers. As a result, you’ll see that error message. This problem can easily be solved by disabling the VPN you’re using.
Ethernet Adapter: In some cases, the error message may appear because of your system’s Ethernet adapter. It turns out that in some cases, your Ethernet adapter is faulty, preventing the Office from connecting to the Internet. This problem can easily be solved by simply restarting the adapter.
List of networks and location services: Finally, another reason for the error message could be two network services, which can be found in the Windows Services window. As in the case of the Ethernet adapter, simply restart the corresponding network services and it will work again.
In some cases, Office will only start in offline mode, resulting in an error message. Before we proceed, it is important to note that in some cases, Office will start in offline mode only.
Try connecting to the Internet by selecting the File menu, then the Account tab. You’ll find an option for this at the bottom-left corner. If that doesn’t work, try the methods below.
