9 times out of 10, that error indicates temporary problems on your ISP's
end. Assuming your account is configured properly, access your account via
the webmail page until the problem automagically clears up.
Make certain your time, date, and /time zone/ settings are correct.
Temporarily disable your third-party firewall [BE CAREFUL! Enable the
Windows Firewall immediately after doing so!], any "system protections"
(e.g., anti-virus application/security suite; many anti-spyware applications
other than Defender), and any third-party pop-up/ad blockers to see if
If you use a router, you may need to adjust MTU values:
IE Tools | Internet Options | Advanced | HTTP 1.1 | toggle on/off; "Use HTTP
1.1 through proxy connections" must *not* be checked.
IE Tools | Internet Options | Security | [zone in which Windows Mail runs;
should be Restricted Sites] | Custom Level | User Authentication | Logon |
toggle between the setting choices here [All options EXCEPT 'Automatic logon
only in Intranet zone' work for me; currently 'Anonymous logon' is checked]
Resetting either or both of the 2 IE Tabs above to the defaults might help,
