Office 365 may not be working due to issues with office activation, down servers, browser issues, login issues, update issues, and ad-ins problems. Some other issues can be that your internet connection might be down, your login credentials are wrong, or the office is having synchronization issues, and so on.

If you want to know how you can check the real problem for the office to go down and also want to know how you can solve those problems then this article is just for you. Read the article below and you can start working with Office 365 as I have found, tried, and succeeded with the below problems with their solutions.

What Are The Possible Reasons For Office 365 Not Working?

Any application, even Office 365 may have problems you have to deal with. Not all problems are brought on by software vendor-unpatched defects. From the client-side, several problems can be resolved.

Let’s see the possible reasons why the office might not be working. Below are some of the possible reasons for the office to crash/not work.

Issues With Office 365 Activation

Firstly, your office 365 has to be activated to work inside office 365 applications. When you try to open the office without activation it will show a “Product Deactivated” error message. It will also display the following option:

Product Deactivated

To keep using Word without interruption, choose the option below to reactivate

Enter keyI have a product key.

Sign InAdd this computer to an active account.


The installed Office 365 apps are inactive until they establish a connection with Microsoft licensing servers and the license is renewed if they are disconnected from Microsoft servers for more than 30 days in a row.

Office 365 activation problems might arise if numerous versions of Microsoft Office are installed on your device.

Safari Browser Issues

When using Office 365 online apps, Safari may have issues because of the browser’s Intelligent Tracking Prevention (ITP) function. The webpage might not be compatible with the browser settings

Issues With Login

You can run into a sign-in issue while attempting to enter into your Office 365 account. The error typically appears when you input incorrect login information. It might display the error as:

“We are unable to recognize this user ID or Password”


Another reason might be that your administrator changed your password without telling you. You need to ask him/her to provide you with the login information so you can log in.

Synchronization Issues

Office 365 syncing issues are frequent for Office Mobile, but occasionally, problems with OneDrive and Outlook on the desktop version of Office 365 can be similar.

Users are reporting that they are observing differences between the messages that they receive in Microsoft Outlook compared to Microsoft Outlook Web App. People are also receiving an error message when they synchronize their offline folder file (.ost) in Outlook while their mailbox on a server is running in Microsoft Exchange Server.

The error messages are displayed like:

Cannot start Microsoft Outlook.

Cannot open the Outlook window. The set of folders cannot be opened. The file c:\Users\<username>\AppData\Local\Microsoft\Outlook<[email protected]> is not an Outlook data file (ost).

One time I also had an issue regarding synchronization. Even though I synced all my email messages, appointments, contacts, tasks, notes, and documents in my, ost file. It was missing from my .ost file/ my mailbox.

To fix synchronization issues you can uninstall some applications on your PC or repair office 365.

Update Issues

The Microsoft team is updating Windows, Microsoft Office, and other software regularly and they are continuously fixing the threats, bugs, etc for their users. So, as the office is updated from the team side, the users might not be updating the office on their devices.

So, if the client-side doesn’t update the office once the update is released, they might face some issues. Sometimes the update might also fail. There are a lot of different reasons for the updating issues.

Before updating the office you must check your Operating System (OS), your internet connection, firewall settings, Office 365 subscriptions, etc.

Office 365 Problems Caused by Add-Ins

Examine the installed Add-Ins for Office 365 apps. Microsoft Office issues can occasionally be brought on by Add-Ins. Low performance or application crashes are examples of these issues. Try turning off Add-Ins so you can use Office 365 programs without them.

Office 365 might display something as:

Sorry, we had to restart because this add-in wasn’t responding


This often occurs if the user takes longer than 5 seconds to choose local files in the dialog box.

Method 1: Check Your Login Credentials

Method 2: Check Your Web Browser

Method 3: Change Your Password

Method 4: Unlock Your Account

Let’s discuss the above methods.

Method 1: Check Your Login Credentials

Firstly, check if your login information is correct or not. Sometimes the user is not providing their actual information because they get confused as people have numerous social accounts. Before logging into office 365, make sure that the information is fully correct.

I suggest you note down all the log-in information on your device or somewhere else for such cases. It would be easier for you to log in if you have forgotten the login details.

You can also save your credentials in the browser as soon as you log in so that you won’t have to type it again the next time you want to get into office 365 online.

Method 2: Check Your Web Browser

Firstly, if you are using more than one browser, sign out from the portal. You can also try clearing the cache in the web browser, removing internet cookies and deleting web history, and try signing in again.

Method 3: Change Your Password

If you are still not able to log in and you don’t know if the information that you are providing to login into office 365 is correct or not. Then you can try to change the password from the login page.

Click on the “Forgot Password” option where you are asked to type in your passcode. Then you will be directed to another page where you have to provide your email info. Also, don’t forget to type in the captcha correctly and verify yourself.

Then you will be asked to complete your cellphone number and after that, you will get a verification code in the number that you have provided. You can choose to obtain the code in either text or code.

After you get the verification code in your number, provide the code. Then you will be redirected to another page where you will be asked to reset your password. Put a strong password and don’t forget to note it down.

Method 4: Unlock Your Account

Your account can be locked if possible violations of office 365’s Terms of Use include activities that are connected to your account. To unlock your account, you can use any phone number to request the security code and the number doesn’t need to be associated with your account

The phone doesn’t need to be connected to the internet or nor does it have to be a smartphone. It just needs to have a sim network as you can receive text messages on your sim card. After doing so, you may have to create a new password to get into your account.
