Outlook sign in issue

[RadVA]

I have been using Outlook with no problems. Today I try to read messages and
it keeps asking for user name and password. Never had to before. I went
into security and changed password and user name still asks me over and over
for sign in. If I cancel it gives me errors. I added the email again and
put in new username and password and still it will not let me get to incoming
mail. It just keeps asking me for correct user name and password. HELP!
What can I do to correct this?
Thanks in advance.

I have the same problem. It started today. My isp has tried everything and
said it must be a microsoft software issue.

If you are sure you are using the correct username and password,
one possible cause for that error is account corruption. One thing
you might try as a possible quick fix is to delete that corrupted
account, restart Windows Mail, then recreate that mail account.
If that doesn't fix it, more drastic measures will have to be taken.

Which antivirus are you running?
As a minimum, email scanning in the antivirus must be turned off,
although that may not be sufficient to eliminate all bad effects.
In a worst case scenario, your antivirus may need to be uninstalled.

If turning off the email scanning function does not resolve your problem,
consider upgrading to Windows Live Mail, because it is less prone to
suffering bad effects from overly aggressive antivirus programs.

Email scanning in any antivirus must be disabled, for reasons
