Zoho CRM Error message #2 : Fixing [Invalid Credentials] and [Authentication Fail] while configuring IMAP



Hi Everyone!

As a part of our Zoho CRM Error messages series, we're going to focus on couple of error messages that you might encounter while configuring IMAP and ways to resolve them. These are:

  • [Invalid Credentials]

  • [Authentication Fail]

 

The annoying part is that sometimes you get these error messages despite entering the correct credentials. Troubleshooting these errors start with understanding the root cause of these errors. You get these errors when:

  • TFA (two factor authentication) is enabled for your account

  • An previously saved password gets auto filled while configuring but you changed the account password recently.

  • When an incorrect server name is entered. For e.g., the user might be in zoho.eu domain but entered the domain name as zoho.com.

 

How can you resolve these errors?

  • If TFA is enabled: Generate app specific password for your email account from the "Two Factor Authentication" section in your Zoho Accounts page and use the same for IMAP configuration. More on that here.

       

       

 

 

  • Password auto fill: If a previously saved password gets auto filled and you have changed the password since then, ensure you retype the password manually while configuring.

  • Ensure you use the correct hosted server name while configuring IMAP.

  • Ensure you are logged in to web mail while configuring the IMAP.

 

Hope this helps resolve the error messages encountered while configuring IMAP. If the issue persists, do post in our community or contact our support team for the fix. 

We will continue to add more fixes to other prominent error messages in the coming weeks. Stay tuned!

What sets you apart as a sales person is your ability to add that personal touch to your business relationship with your customers. Sending a gift on a special day, or leaving a note wishing them on their birthdays, are small, yet significant actions that show your customers that you care. And these are actions done without any expectations :) You must be engaging with a lot of customers and it is highly unlikely that they all are your friends on Facebook or some social channel,

Or have it pull that information automatically from the CRM? We are wanting to use this as a field management software but it is difficult to pull the address from multiple sources when it would be ideal to have a clickable address on the appointment screen that opens up the user's maps.  It would also be advantageous for the "list view" to show appointment times instead of just duration and booking

Is there a reason for having the configuration panel not taking the full width? Its impossible at this width to edit panels that have a lot of elements. Please change it to 100% so we can better edit the layouts. Thanks! B.

                                                                                                                Hi, On my Deal page I have a field which has a rule against it. Depending on the value entered, depends on which further fields are displayed. When I convert a Lead and select for a Deal to be created as well, all fields are shown, regardless of the value

                                                                                                                Good morning. Let me introduce myself, I'm Iky from Indonesia. I'm experiencing an error or problem using Zoho Forms. I manage Zoho Forms, but I previously encountered an error when I misclicked the delete button in the upload format. It apparently deleted

                                                                                                                初心者です。 ZOHO FORM で宿泊者名簿を作っています。 ゲストが、URLをクリックするとStripeで支払いができるようにURLを表示をしたいのですが、 上手くできません。 やり方が分かる方、ぜひ教えてください。

                                                                                                                I fear I know the answer to this already, but thought I'd ask the question. I created a custom module and instead of having a name as being the primary field, I changed it to an auto-number. I didn't realise that all searches would only show this reference.

                                                                                                                When I'm adding to notes on the app, I have to add spaces between words myself, rather than it automatically doing it. All my other apps add spacing, so it must be something with Zoho. Is there a setting I need to change, or something else I can do so
