oops a server error occurred and your email was not sent

Tried sending out an email and ran into a problem? Google is telling you that oops... a server error occurred and your email was not sent. (#007) and you have no idea what to do? Weirdly enough, this error is actually a pretty common one between Gmail users and the cause for it is really quite simple.

But what actually is Gmail 007 error?

The 007 error has disappointingly nothing to do with your emails being intercepted by James Bond. Instead, the server error is result of some of the Lab features on Gmail. Lab features, as their name suggests, are experimental, pre-release options that can be enabled by users to infuse their inboxes with business functionality.

However, because some of these features are still in an embryonic phase and have not been fully-tested, sometimes they rebel against their masters, making something that could only be described as a mini zombie apocalypse.

The problems are big and clear - you can't properly send an email!

There's no need to despair though. Oops... a server error occurred and your email was not sent error can be taken care of in just a few steps. 

So without any further ado, let's get to fixing your mail issues and getting rid of the Gmail 007 error.

Steps To Fix Gmail Error 007

As frustrating as it can be, the Gmail 007 error has an easy fix. 

So, here are the 5 steps on how to solve the "oops... a server error occurred and your email was not sent. (#007)" error:

Step 1. Log into your Gmail Account.
Step 2. Go to the icon that looks like a gearbox (you know the one), and select the option for “Settings.”
Step 3. Click on the tab titled “Lab” within “Settings.”
Step 4. Type in, “Background Send” to search
Step 5. Upon locating “Background Send,” disable it

95% of the time, this solution will resolve the issue pretty much immediately and let you return to blissful, uninterrupted emailing, with Error 007 becoming nothing but a distant memory.

However, in some cases, this problem can be a little more resilient and come back after initially going away. These additional measures can be taken to make it disappear once and for all.

  • Update your browser so that it uses the latest version
  • Delete your cache and clear away the cookies
  • Disable all browser extensions/add-ons
  • Restart your Web Browser
  • Try re-opening Gmail without Labs
  • Disable your virus scanner.  If the issue disappears after that, it's possible you may need to consult with the parent company of the anti-virus software - it's rare but it's possible it's an issue from their end which can be resolved with a minor patch.

From there, you should be completely sorted! Oops... a server error occurred and your email was not sent. (#007) error should be gone by now! Although, at this point, a question may bother some of you:

What does the “Background Send” lab do?

Some users may be wondering, “What sacrifice are we being asked when we disable the "Background Send"?  After all, the instructions above did suggest the disabling of a lab. Fortunately, while this lab is quite useful - it's far from necessary. 

Background Send simply enables your account to be able to continue sending an email even if you've exited the window, or returned to another folder within your account. Consequently, users with Background Send enabled can depart quickly after firing off an email and spend their time on other matters - saving a fraction of a second or so.

On rare occasions, however, Background Send can lead to Gmail going oops... a server error occurred and your email was not sent. (#007) and you reading this article to find out what in the world happened - not saving any seconds at all.

More Tips To Solve “oops... a server error occurred and your email was not sent (#007)”

If you've done the necessary changes but they don't seem to help, maybe you're actually cursed - and this is about to last forever and ever and ever. Either that - or there's something we haven't covered yet! Luckily, Google technicians have encountered cases when none of the previous remedies seem to work and they have a few tips on what to do in such situations. These are the tips, hints, tricks, and solutions:

  • When did you disable the “Background Send” lab? Changes made to lab settings can take several minutes to come into effect, so it's possible that the program will digest your command in the near future.
  • Try restarting your browser upon applying the change. This can help expedite the process and speeds up the resolution of Error 007.
  • Verify that the error that you're dealing with is, indeed, #007. Other errors, though similar in their manifestation, have different solutions, and consequently what debugs the goose does not debug the gander.
  • Try sending an email from another device. If you find that the same account is able to transmit information without issue on another platform, then the problem lies with the device itself.
  • If you have an attachment included in your email, make sure that it is under Gmail's 25MB limit. If not, you will receive a very similar (albeit different) message informing of a failure to send.  

The good news is that if you take all of the steps previously-outlined, the dreaded “oops... a server error occurred and your email was not sent. (#007)” is almost guaranteed to disappear.  While some sites claim that it is necessary to install their software in order to resolve this problem, be wary of such claims.

These companies are wolves in sheep's clothing and their software could be anything from ransomware that hijacks your computer's files until a ransom is paid to spyware that extracts private information from your databases. No additional software is needed to fix this problem, and those telling you it is, have their reasons to do so.

On a final note:  While “Background Send” is still in development and at the present time can still bear a few bugs, if you rely on it for your daily operations, don't panic!

Just because it had to be temporarily suspended to address an error #007 now doesn't mean that Google is not working to resolve the matter - at a later point everything might get very nicely fixed up. A brief disabling of “Background Send” may not be a permanent farewell, but just a quick “smell ya later!” as it goes in for repairs.

Think of it, not as a friend that has died, but one who's on the mend and will soon be ready to join you in the sending of emails once again!
