Try Outgoing 465.



Assuming that doesn't fix it, which it probably won't, you need to enable "Less Secure Apps Allowed" in your Gmail account for use with Outlook—check that setting in Gmail.

Thanks for the reply, and yeah, that didn't work.


And I have already checked all of my accounts, all of them are already set to "Less Secure Apps Allowed". I found that info online when I started to have problems, but mine were already set to that, so that is not what is causing the problem.



So I am dumbfounded... All of a sudden July 31, everything stops.. All Gmail accounts. I have even installed Thunderbird to test it, and the same problem happens.
