Using older versions of Outlook for Mac in business environments
The reason I'm not moving my yahoo account to anywhere else is that I've opened it back in early 2000s, when I received a feature to make free "fake" emails within my one main mailbox. This feature now is a plus addition or pro feature for most of the mail companies and you have to pay extra money for that. Even in Yahoo if you open a new account this feature isn't free anymore. Yes, I'm aware that you can make fake emails in gmail with +words@ tricks on your mail address, but that feels weird and not actually working as I would like it to work. So I stick to my yahoo mailbox and use it whenever I sign up for a website, I create a special email address to those sites and I can keep count and follow-up on their communication, or just simply delete the email address without any drawbacks and get rid of spam mails like this easily.
I've yet to ask yahoo support for their side of the story and if they can do a workaround for the issue to get rid of...
