  1. Thanks Saurabh, It worked for me too!

  2. Well, that’s not really a fix, it’s a work around, and it takes forever to sync, so I’d rather the damn thing not get stuck in the first place. Haven’t had it happen before that I can remember, but now it’s happened twice in the last two days. Thanks for the info, though!

  3. clearing the app data and forcing the app to stop does nothing. upgrade to the latest version. the emails stuck that say sending is a result of the older app loaded. go to the play store and update to the latest version ;)

  4. Wish I read before trying this fix. IT DELETED MY EMAILS! Thanks :-/

  5. PLEASE EDIT YOUR POST TO TELL PEOPLE THAT THEIR EMAILS IN THE OUTBOX WILL BE DELETED! The way you have it worded made me think that those emails would be sent after I completed the fix – instead they were deleted and they are now lost forever.

  6. Cheers for this fix. It DOES work, and syncing took just a few seconds. You only loose stuff in the outbox – everything else is synced with desktop.

    I was reluctant to update Gmail because of those dumb village-idiot messages: “You’ve finished. Enjoy your day!” and “No trash here. Thanks for recycling!”

  7. When i compare the stuck emails in sending 30 of them this last issue, over 200 lost due to not knowing they would be deleted, none of them were sent and do not show up as sent in the desktop version so it apears that both the phone app and web based gmail reader is justvery poorly designed,b ulky, and not worth the effort. i dont know if all samsung smartphones are jury rigged with google but they have enticed me to purchase my next smartphone from someone else. BTW, the last sync after deleting data took i dont know how many days.

  8. This happens because Google wants to take over your e-mail service; in other words you must be using your Android or smartphone’s e-mail app instead of Google’s GMAIL App. There are two fixes to this problem, first is to download Goggle’s GMAIL App and use that for email communication; and second is to ask google to allow ‘less secure’ apps i.e. non-google to access your e-mails (i know!) Here are the steps for the second option:

    Allowing less secure apps to access your account

    Google may block sign-in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safe.

    Some examples of apps that do not support the latest security standards include:

    The Mail app on your iPhone or iPad with iOS 6 or below
    The Mail app on your Windows phone preceding the 8.1 release
    Some Desktop mail clients like Microsoft Outlook and Mozilla Thunderbird
    Change account access for less secure apps
    To help keep Google Apps users’ accounts secure, we may block less secure apps from accessing Google Apps accounts. As a Google Apps user, you will see a “Password incorrect” error when trying to sign in. If this is the case, you have two options:

    Option 1: Upgrade to a more secure app that uses the most up to date security measures. All Google products, like Gmail, use the latest security measures.
    Option 2: Change your settings to allow less secure apps to access your account. We don’t recommend this option because it might make it easier for someone to break into your account. If you want to allow access anyway, follow these steps:
    Go to the “Less secure apps” section in My Account.
    Next to “Access for less secure apps,” select Turn on. (Note to Google Apps users: This setting is hidden if your administrator has locked less secure app account access.)
    If you still can’t sign in to your account, the “password incorrect” error might be caused by a different reason.

  9. This always works.. Easy fix.. When anything is stuck in outbox, simply power phone off and on. All stuck emails get booted thru once phone is powered up again. Works every time. Never failed yet.. I know it’s very annoying to send an email to someone, only to realize it’s been stuck for some time.. Hope this helps everyone… Cheers…

    its better not to give any idea than giving dangerous ideas

  11. Clear data removes all settings, deletes everything. Like cutting off you finger when you get a bruise.

  12. Wow! Superb it is. Thanks for your service.

  13. THIS DOESNT WORK……………….

  14. Virginia Bennett says:

    I tried everything else and was about to give up and THIS worked! Thanks so much!

  15. Is there a way to recover lost emails in the outbox? ? I loss my sent emails! Any help appreciated

  16. Worked for me – thank you!!!!! (Nov-2016!)

  17. Has no one ever tried restarting their phone when this happens? It’s super simple, the emails are not lost, they send immediately upon Android load, and no sync necessary. The simplest answer is usually correct…

  18. GOOGLE put Resent Button on UI. Dumb designers!

  19. George Burdell says:

    Don’t try this. It is only a temporary fix and will delete all your outgoing emails. As of 2017, this bug still exists. From posts I’ve read on other sites, it’s existed at least since 2014. In my opinion, Google has had plenty of time to address it and has not. So, no more GMail app for reading my IMAP email. I’m switching immediately.

  20. Clearing cache isn’t showing up as an option. Uninstall or force stop is all that I have

  21. I used “clear cache” instead of “clear data.” The such emails sent immediately.

    Next time (this is a rare occurrence) I will try turning off and on.

  22. It’s ridiculous that this problem is still ongoing. I have Moto Z Play which recently just auto-updated to Nougat (Android 7.0), and today I emailed two photos and they kept showing up in Outbox as “queued”. I was on home Wi-Fi. There was no way I could find to force them to be sent on the spot, including going to Accounts Sync menu and disabling/enabling sync on Gmail.

    Fortunately I found that switching to Airplane mode and immediately switching back to wireless mode (i.e., disabling Airplane mode) forced the emails with photo attachments to be sent out on the spot.

  23. Worked for me! Thank you so verrrrryyyy much!

  24. Amazingly, it seems like the problem persists. Here it is June 2017, and I’m having the same problem. I’ve used a gmail app for years with no issues. But as of today, I can’t send anything – goes into “outbox”, says “queuing”, but doesn’t give an option to send. I’m using wifi, not roaming or anything.
    As per the various suggestions in this thread, I’ve tried powering off/on, clearing cache, toggling airplane mode, attempting to update app (it’s up to date), and exploring gmail/app/account settings. No response – outbox messages never sent, and new outgoing messages just go to the outbox. Clearing data solved the problem for exactly one email – one line of text (no attachment) went through just fine! But as soon as I attempted to send something with an attachment, it once again started putting all outgoing messages (with or without attachment) into the outbox with no option to actually send. Very disappointing.

  25. Hi, I use the latest version of the Gmail app and have tried the above said steps but it still doesnt work. Please help

  26. 3 years later and still the problem continues but this time its more intense.

    1. Clear cache, Clear Data did not help
    2. Force Stop App did not help
    3. Uninstall and Reinstall gmail app on android did not help
    4. Restart phone (complete shut down, battery removed, sim reinserted) did not help

    What else can be tried? Anyone with more solutions?

  27. None of the above worked for me. I have a Nexus 5x and updated Gmail app today. I sent an email with an image, but it is stuck in Outbox. I tried restart, cleaning the cache, and clearing the data several times . But nothing works. . Finally, had to send the file through Whatsapp. Very frustrating

  28. its not working for me
    i am still not able to send any mails
    its always in outbox showing queued someone please give me a solution….

  29. ‫ still having problems with sending emails from my gmail account
