Sbcglobal email keeps making me change password on windows pc

We've been having the same issue for months.  We thought it was because we added a new laptop to the mic since it seemed to start happening at that time period.  So frustrating. Also the laptop doesn't get all the emails that the PC and the phones get on the same email address.. so when he uses it for work and asks someone a question via email he may have to check his phone or the PC to see if they responded.  

I see the issue with resetting email passwords goes back 3 months or more.  This is still an ongoing issue with a family members account.  She is 85 years old and is getting quite upset that she is having to change her password almost daily.  She depends on access to her email for family communication as well as volunteer schedules she needs to keep track of.  Clearing her cache and cookies did not help and she is very confused having to keep track of so many new emails.  WHAT IS THE SOLUTION HERE????

We noticed that you can keep resetting using the same password each time.  Not sure why it's doing it, but that helped somewhat since before that we kept writing down down a new password daily. So frustrating. 

I'M FRICKING FED UP WITH THIS ATT.  They supposedly fixed this several months ago as they said they found an issue, but that it bologne as it still is ongoing and everyone else on here is having the same problem.  I GUESS ATT DOESN'T CARE ABOUT THEIR COMMUNITY FORUMS and interesting that NO ONE FROM ATT is helping to try and resolve it!!!!!!!!!!!!!!!!!!!!!!!!!!!
