I need some help with a gmail account that I use in Mac Mail. I have used it in Mac Mail for a year until two days ago when it stopped working. I have two gmail accounts set up in Mac Mail. One still works- all of a sudden, the other stopped working. I couldn't access any mail, send mail, and I just got the little grey triangle next to it. Couldn't take it online or do anything with it. It also stopped working on my iPhone, iPad and MacBook. It works fine when accessed through gmail.com. I've tried to delete it through Mail Preferences and then put it back in to no avail (just says "cannot access gmail imap server, your password and or username are wrong), tried to delete the password in my keychain (which still didn't work). Does anyone have any idea how to fix this problem? I have seen many issues with it online through a google search, but none have a solution. Thank you!
