A friend of mine logged in to his Yahoo mail yesterday on his laptop, and found his emails only went back 3 months. After that you couldn’t scroll any further and it only gave you the option to search for older emails… Not good.
This problem was only on laptop/desktop — his phone app let him browse back years. I had no idea why this would be the case but noticed he was using Microsoft Edge as his browser.
I installed Google Chrome for him and it was absolutely perfect — a much cleaner display and he could scroll back in his emails as far as he liked. Strange but true…
I also recommended he switch form Yahoo to Gmail as soon as possible… :-)
