我在outlook、gmail分别有两个邮件账号，现在分别登录了其中的一个hotmail和gmail账户后，另一个outlook账户和另一个别名的gmail账户都登录不上去了（原本计划登录一个outlook、一个hotmail、两个gmail账户的），总是提示验证失败。请检查用户名和密码 Exchange auth error ，我尝试删除 Cookie 和 “已保存密码”，依然无法登录，请求工作人员的帮助！ ------------------------------------------------------------------------------------------------ I have two email accounts, one in Outlook and one in Gmail. After logging into one of my Hotmail and Gmail accounts, I can't log into either my other Outlook account or my Gmail alias (my original plan was to log into one Outlook, one Hotmail, and both Gmail accounts). I keep getting the "Authentication failed" message: "Please check your username and password. Exchange auth error." I've tried deleting my cookies and "saved passwords," but I still can't log in. Please help!
