I didn't comment on a month old thread until after you resurrected it... you're absolutely right!
The advice I offered was that your advice was inaccurate. You never mentioned Two-Step in your first post. If you had, there would have been no problem. You did not clarify your post until you were challenged.
Patrick never came back to say that the solution dilbert offered seven minutes after patrick's last post did not work. Usually, if the solution doesn't work, the OP will come back for more advice.
Patrick never mentioned Two-Step verification.
The solutions offered have solved the error message in the past, as proven by previous threads on this forum, as well as others.
The error message is not specific to Two-Step verification issues.
In short, your advice was inaccurate, and unrelated to the OP's statements. Perhaps if you had qualified your statement, like: "If you have Two-Step verification enabled, then you cannot use the same password on your mobile device as you use on your computer. go to Outlook under security information and add App Password to your phone."
Throwing out a possible answer, without it being relevant to what the OP describes, is a waste of time, as is resurrecting month-old threads.
Now, since your only contribution to this forum has been inaccurate advice, reviving a dead thread, and being an argumentative and insulting individual... perhaps you should seek another forum?
