Hotmail / Outlook not working

[SpaceStar1]

Hi,
all of a sudden outlook mail stopped working, and started working next day, then stopped working again permanently.
It gives this message: Your current User-Agent string appears to be from an automated process
(This happened over 6 months ago, the idiots must've changed something.)

I delete cookies, new profile, nothing helps.
Is there a simple about config setting change, or something else to do?

thanx.

Try this: open about:config, search for "outlook", make general.useragent.override.outlook.com blank (and perhaps the same for live.com).

No it didnt work, it gave this:

Then it went back to previous error page when I reloaded.

Is there anything else?

Brave searching Hotmail.com and going to the link gives me the same error, but searching the error issue led me to an answer. Go to https://www.office.com/ and choose Products, then Outlook, and the site works.

I did that but it still didn't work. It logs into copilot tho. But from that side menu if outlook is clicked it goes to a blank screen, even with all scripts activated.
What else could it be?

Try this: open about:config, search for "outlook", make general.useragent.override.outlook.com blank (and perhaps the same for live.com).

What do you mean "Blank" ?

It doesn't work for me.

Blank as in "delete the content", make the value be an empty string (not a space, empty.) Doing that will allow the application-wide user-agent to be used instead.
