Google Apps is really great, the ability to use the power of Google services in combination with your domain is worth a lot.
However, for a long time for me (and many others, judging by unanswered questions in the internet) there was a problem - the wild behavior of a captcha, in particular when working with mail through outluk, I had to perform a dreary unblocking procedure every day. As it turned out, the whole thing was in the password, the service found it too simple (it really was) and turned on the preventive protection mechanism ... it was enough to change the password to a more intricate one and for more than a month I don’t communicate with the captcha.
This recipe was developed by chance, I have never met such advice anywhere and xs, maybe I have hallucinations.
