I am having trouble with Yahoo mail. Their support costs as a subscription IM does not answer Can get incoming mail, but cannot delete, reply, archive, marked them as Spam, cannot forward I have used Yahoo for 2.5 yrs with no problem and this all started 2 days ago around 3PM EST
Yahoo seems to go through rough spots about twice a year. For the last 2 days, it will not let me stay signed in, & makes me sign in on one window, then opens another window for me to sign in again. It seems to be an ATT/yahoo coordination problem. I have been with Yahoo since 'the beginning'-actually mine is still listed as a Prodigy account! Try signing out on all your devices, then sign in again. Good luck.
Update ============== After starting to switch over accounts to AOL ( including this site) I went back to yahoo to look at something and wouldn't ya know it. It's back running like nothing happened It sucks to transfer email accounts along with contact lists but I'm no too far into it ( give me some thing to do while waiting for my front vac. operated front locking hubs and front wheel bearings for my 2011 F150
