Windows 10: Problems with Outlook.live.com

Since the last Windows Update in my PC I can't open Outlook.live.com. Error 400 is shown all the time. I reseted the password, I used Authenticator, but nothing. It's not a problem with my password since I can login in from my mobile. Does anybody know how to fix it? Thanks in advance.

How to install outlook express on windows xp with explorer 8?

This is an awkward problem to solve and one I don't think is worth the time and effort.

The OP would be better off either using a modern webmail service like gmail or outlook.com or using a modern email client like Windows Live Mail like FX-GMC suggested or Thunderbird from Mozilla. If nothing else, Outlook Distress was notorious for corrupting its data files and losing all your email in one easy step. Not worth it.

 

Outlook 2016 problems

As suggested by Appleoddity, the first step is to disable all your add-ins to determine whether the issue is caused by a problematic add-in.

If issue still continues when all add-ins are disabled, then you can try renaming the following \Outlook registry key to \Outlook-1 when Outlook is closed:

Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook

Then, start Outlook and create your new profile to test it. When you start Outlook in safe mode, most of the customization settings are disabled, and these customization settings are stored in the \Outlook registry key. If it doesn't work, you can just renaming the newly generated \Outlook key to \Outlook-2, and then rename the \Outlook-1 key back to \Outlook.

 

Migrate suggested contact (semi-automatic) Windows Live Mail To Outlook

I'm afraid that Windows Live Mail doesn't have the same sort of addressee suggestions that some other programs like Office Outlook have. When addressing a message in Windows Live Mail, the only 'suggestions' that appear are entries in the contacts list that
match the string typed in the address box. Outlook also maintains a list of 'people you have sent mail to in the past who may or may not be in your contacts list,' its
AutoComplete list. Windows Live Mail doesn't do that.

I'm sorry, but it's not quite clear to me what your customer is expecting.
