This error can also occur with multiple different numbers but occurs after you enter your username but before you can enter your password. For more advanced or persistent cases, reviewing Azure AD sign-in logs, double-checking MFA setups, or investigating Conditional Access policies may be necessary. And if your environment is particularly security-conscious, keep in mind that policy-based blocks on specific devices or geographic regions can also interfere with Office activation. In these scenarios, you’ll need more in-depth knowledge of Office 365 licensing, Azure Active Directory (Azure AD) configurations, or advanced policy settings.

Find solutions to common problems or get help from a support agent. If you’re lucky, you’ll find your problem covered, and SaRA will fix it for you. A window opens to ask you if you’re ready to commence repairs. With the Quick Repair radio button selected, click the Repair button near the bottom right corner of the window. Below I will list a few things that can cause update problems in Office 365.

On a PC, simply exit out of all open programs and restart the entire machine. Check to see if multiple copies of Office are installed on your system. To do this, navigate to Control Panel and click on "Programs and Features".

Some Huawei routers give out broken IPv6 DNS settings, so disabling this avoids future issues.

Strangely enough, many users started facing the same issue after downloading the version 2504 update, which was released for Outlook for Microsoft 365 at the beginning of June. Microsoft has once again acknowledged the issue, but this time they have also explained the reason behind the crash. Shivam is a digital marketer and technical content writer at DRS Solution®, specializing in topics like databases, email recovery, and migration solutions.

If you’re lucky, when you open your formerly balky or misbehaving Windows app, all will be well. You’re working on a document or a spreadsheet, or using email, and BAM! One of your Microsoft Office applications starts acting weird or stops responding. If one or more Office apps is acting glitchy, work your way through this series of repair maneuvers, starting with the simplest.

If problems persist, consider visiting the Microsoft Support website for further assistance or updates specific to your version of Office. If you or your users find Office is taking a very long time to install, try installing using an offline installation. See Use the Office 2016 offline installer and select the Office for business tab.

And of course, webmail is working without issues. So it is not a full server crash or a firewall misconfiguration. It is not something we can fix on the Customer Side. Xfinity uses a backend similar to what I use to work with personally 10 years ago, so I have a general idea of it. I did stop getting outlook mail around late afternoon early evening yesterday.

To sum up, the blog elaborated on all the major reasons for Microsoft Outlook keeps crashing problem.

Passwords have been around for centuries and people have been losing them for that long too. Even the Romans used encryption to try to protect their passwords. I can open any Office 2016 app installed on my computer but I am unable to link/login to my Office 365 account on my primary computer. I have a service spare that I tested with and I am able to login to Office 365 without any issue. I have done a number of searches and found related issues but none of those fixes have worked.
