my Hotmail continues to ask me for my password on my iphone 7. I get a message saying "enter the password for outlook account" with the option to cancel or edit settings. If I hit cancel the message pops up again, and if I go to edit settings, I have to reenter the password. At times, if the account is open, I get a message saying "Password Required enter the password for the Account account "(null)". This happened periodically with my new phone, but is happening more often in the last few weeks since I upgraded. I need my phone to access email because I don't have a home computer! Can someone help? Thank you!
