I am having a new problem with Outlook and Gmail. I've set up hundreds of email accounts in various formats but this one has me stumped. I use MS Office 2010/Outlook. Just recently, without anything having been changed, Outlook cannot connect to my gmail account. I constantly get a pop-up asking for my username and password for my gmail account. And I enter it but it keeps failing. So I tried removing the gmail account and reinstalling it but to no avail. It never passes the test message. Does anyone have any suggestion on how to solve this problem? One odd thing I noticed is that my pst file for gmail is huge. I'm not sure if that has anything to do with it.
