As of my knowledge cutoff in September 2021, there were no official announcements regarding the complete phasing out of Yahoo Mail. However, it's essential to stay updated with the latest news and developments from Yahoo to know if there have been any changes in their plans. Companies occasionally make strategic shifts in their services, and email platforms are no exception. It's advisable for Yahoo Mail users to regularly check official Yahoo communications or news sources for any updates regarding the future of Yahoo Mail.
