I have a serious “Offline” Problem. In spite of trying all the options, the Outgoing Mail Server remains “Offline” only. Initially it does look like it will work, but after a while it turns to “Offline”. I have Gmail account and I can only receive e-mail but can not send out. Surprisingly, it does work on my iPhone as well as on iPad, but doesn’t work on MacBook Air.This has happened after my office e-mail was changed to two step security(which is a company e-mail but through gmail only)successfully but my personal gmail id has this problem of going “offline”Can you help ??

I had been fighting with this for ages and tried all of the solutions listed to no avail. I finally went back into the server list again, opened up my desired offline server and removed my password. I realized that my working servers did not have a password for the smtp server. That did the trick. I tested and tested and I am back in business!
