Solved: Your E-mail Server Rejected Your Login – Outlook Error

Though it is pretty simple to set up Gmail on Outlook, but at times you get the error, “Your e-mail server rejected your login”. Despite you enter the correct password, Outlook prompts for password again-and-again.

In this tutorial we will guide you step-by-step on How to get rid of one of the below errors by configuring your Google account Security (2-Step Verification, App Passwords ) settings:

  • Log onto incoming mail server (imap): the server rejected your logon. Verify that your user name and password are correct“.
  • “Something Went Wrong, We weren’t able to set up your Google account with IMAP. You may need to make changes to your Gmail settings“.
  • Popup “Enter your username or password for the following servers“.
  • Log onto incoming mail server (POP3): Your e-mail server rejected your login. Verify your user name and password for this account in Account Settings. The server responded: -Err [AUTH] Username and password not accepted“.
  • “Send test e-mail message: Your e-mail server rejected your login. Verify your user name and password for this account in Account Settings“.

These errors come during the setup of Gmail on Outlook or when you run the Send/Receive for an existing configured Gmail account.

Following topics will be covered in tutorial:

  • What is the Cause of Error?
  • Set Up 2 Step Verification & App Passwords
  • How To Set Up Gmail in MS Outlook

01. What is the Cause of Error?

Google had announced that it is disabling the Less Secure Apps feature in Gmail account from 30th May 2022. After this deadline you may get the error “Your e-mail server rejected your login….” or the ones listed above, on Outlook.

Unless until you don’t update your Gmail Security settings Gmail would not allow Outlook to verify your username/password, as a result you won’t be able to receive emails in Outlook.

There are two ways to remove this error:

  1. Enable 2-Step Verification
  2. Generate App Passwords

Two-Step Verification

The 2-Step Verification adds extra security layer to your Gmail account in-case your password is stolen or someone tries to access your account. It verifies your phone number by sending a code as an SMS (text message). Once you get the code you have to add it in the 2-Step Verification settings.

The new versions of MS Outlook support 2-Step Verification, you don’t need to generate App password. Once the verification process is completed you can set up Gmail on Outlook and Send/Receive emails.

App Passwords

App Passwords feature generates a secure Password that you can use to sign in to Gmail account from apps on devices that don’t support 2-Step Verification. It grants complete access to your Gmail account.

You have to enter the password once, so no need to remember it or save somewhere.

    This worked great with my gmail.com account. Is there a similar solution for hotmail.com? I am receiving the same error from my hotmail.com account (which I believe is now outlook.com) when attempting to view hotmail from Outlook 2007 email client.

    Thanks,
    Steve

    Thanks Steve. Surely we will look for Hotmail problem as well, and try to find a solution.

    Thank you for your very quick response. I’ve been working on this for two days. I think I just found a workaround for hotmail. This must be setup from inside your hotmail.com account.

    1. Open up your hotmail account
    2. Click on “Settings” icon (gear icon on top right side)
    3. Click “View all Outlook settings” (bottom right side)
    4. Click “Mail” on left side
    5. Click “Sync email”
    6. Scroll down to Pop and IMAP – Pop Options
    7. Click on bullet “Let devices and apps use POP” – Yes
    8. Then “Devices and apps that use POP can be set to delete messages….”
    9. Check which option (leave messages on server or not) you wish.

    This worked for me. How convoluted that Microsoft would not make this more readily available or at least mention this more often. But then again, it’s Microsoft.

    Again, thank you very much for your time. Hopefully this will be of a benefit to others.

    Good Luck,
    Steve K.

    I ran into another little glitch. I first tested this on a Win10 machine and all worked fine. I then tried it on an older Win7 machine. I ran into a few problems.

    1. I received an error #0x800408FC. To resolve, I had to disable IPv6 network protocol (Run ncpa.cpl > select network card > properties > uncheck TCP/IPv6).

    2. I ran an outlook test from the Control Panel > Mail > Profiles > Properties > Accounts > change > Test Account Settings. All worked fine including the test message going out and coming back into my mail via Outlook. However, when I tried sending an email from Outlook (not the test procedure), the outgoing email does not leave. Outlook continues to try sending but no luck – eventually it times out.

    I’ll keep working on this but at least we know it’s working for Win10 which was my main concern.

    It's always something isn't it. Oh well, like I said, it's only Microsoft. . . .

    Still no luck with my Win7 machine (works perfect with Win10). If I find something I'll let you know but for now I guess I'm done.

    Sorry. . . .

    The issue could be because of Ports! Have you checked ports. Read this article you may find something: *** https://www.meersworld.net/2020/05/how-to-setup-gmail-in-ms-outlook-2010.html ****

    I will look at that but I did try this on two Win7 machines (an HP laptop and Dell desktop) with same results. I'll let you know what I find.

    Thanks for the suggestion. . . .

    Log onto incoming mail server (IMAP): The server rejected your logon. Verify that your user name and password are correct.

    I am still getting this message after following all your steps. I have also disabled Windows defender and I do not have any antivirus/anti-malware apps. Is there something I am missing.? I have been on this issue for quite sometime on multiple laptops.

  22. Meer's World

    April 12, 2021 at 6:01 pm

    Well Windows Defender has nothing do with it…. It seems like you have not enabled IMAP from your GMAIL Settings or you are entering the wrong username and password. Please read this tutorial, it might help you: https://www.meersworld.net/2020/05/how-to-setup-gmail-in-ms-outlook-2010.html

    My Outlook 2010 was working fine on LAN and some Wifi connections for years, then brought up this persistent error with Wifi during travel (both a hotel Wifi and our own usual router). I have checked all account settings, which are correct. Your solution unfortunately doesn't help. Neither does removing an antivirus-related add-in in Outlook. Restarting the laptop makes no difference. I have checked many websites but with so solution so far. Either there is a message that Outlook cannot log on to the mail server, or error 0x800CCC1A, or some such message. But the result is the same — can't use Outlook anymore.

    The WiFi connection that you are using might not be secure.

    Normally such errors are caused by two reasons:

    (1) When there is error related to SSL (Secure Sockets Layer) encryption, like when you set the wrong port numbers on SMTP or POP3 servers. Reconfigure SSL encryption and SMTP & POP Port Number settings.

    You can also try this: Go to Internet Email Settings of your Outlook, under the Incoming Server (POP3), uncheck the "This server requires an encrypted connection(SSL)". Save your settings. Do Send/Receive and see whether it works or not.

    (2) The other major cause of such errors is corrupt PST File. Repair your Outlook PST File. There are tools available to repair this file such as "Inbox Repair tool".

    You can also use "Exchange Remote Connectivity Analyzer (ExRCA)" to troubleshoot connectivity issues.

    Dear Team,
    I have configure gmail account incoming mail pop3.gmail.com port 993 secure ssl but come error Log onto incoming mail server (POP3): Cannot find the e-mail server. Verify the server information in your account properties.

    Kindly guide this issue

      Use “pop.gmail.com” for Incoming mail server, Not “pop3.gmail.com”.

      You can also try Auto Account Setup, you won’t need to configure anything.
