I entered Gmail hell yesterday morning. Whenever I sent an email from within a browser, I got a 707 error back and Gmail would go into an endless “Retry” loop. It was early Monday morning and I wasn’t ready to deal with this, so I grabbed my iPad and did a bunch of email on it. I didn’t connect that the client was working fine, but the browser version wasn’t until I got the office.
The answer was a simple one once I figured it out. I disabled all the Google Labs and it magically started working again. I then re-enabled Labs until I found the one that was causing the 707 error – the “Background Send” Labs. Apparently something broke over the weekend with Background Send and the newest browser version of Gmail.
If you are getting a 707 error, just turn off Background Send. That should fix it.
Consider this a public service announcement as of 11/8/11. When I searched Gmail 707 Error in Google, I didn’t find anything that referred to this. I found a few “clear your browser cache” suggestions, which didn’t help. I also found plenty of “I’ve got this problem” with no answers.
We did contact Google tech support via email and got a response back later in the day to turn off Google Labs to see if that fixed the problem. I also got a similar response from my special magic wormhole tech support line to Google engineering.
This was on the heals of a weekend of Gmail / iOS hell. My email clients on my iPad and my iPhone unexpectedly stopped working on Friday – constantly asking me to login to my Exchange account (I’m using the Exchange connector to access Gmail.) I didn’t figure out what the issue was until Sunday afternoon when I realized that the Gmail iOS app was interfering with the iOS mail app. I’d downloaded the Gmail app on both devices when it came out. It was crappy, but when Google pulled it from the app store, I thought it was novel enough to leave on my iOS devices for a while. Error! Once deleted it, email went back to normal.
Google, I love you, but please amp up the QA!
