Having trouble connecting your email account with our Email in ClickUp using IMAP? Here are some troubleshooting steps you can take.

Check your email provider's IMAP settings

Your IMAP settings will be dependent on the email service you use. Typically you can find these settings within your email account settings or on your email provider's help docs.

Here are some quick links to the most popular email services

Microsoft is making changes to its supported email authentication protocols. Some email services may no longer support using IMAP. You can read more about those changes in this Microsoft support article.

Try using an app password

If your email address requires two-factor authentication or Multi-factor authentication, you may need to use an app password when authorizing via IMAP.
An app password is a 16-digit passcode that gives an app or device permission to access your account. This passcode is generated within your Email provider's settings and then copied into ClickUp.
To generate an Outlook app password:

  1. In the upper-right corner, click your profile avatar.
  2. Click My account.
  3. At the top, click Security.
  4. At the top, click Two-step verification.
  5. Select Set up two-step verification and click Next.
  6. Choose an option and click Next.
  7. Enter your verification code and click Next.
  8. Click Next, then Finish.
  9. Back on the Security page of your account, click Create a new app password under the App passwords section.
  10. Once an app password is generated, copy and paste it into the password section of your ClickUp IMAP settings.

General troubleshooting

  • If you are using an alias, please enter your actual email address.

  • Double-check your formatting for any spelling errors or extra characters. This includes spaces at the end of any fields.

  • If the account can only be accessed via a corporate network or is blocked by a firewall, we will be unable to connect.

Microsoft Exchange specific details


  • ActiveSync must be enabled. When connected we will appear as a mobile device named python-EAS-Client 1.0. You can read more about Exchange's ActiveSync setting here.

  • If Mobile device management (MDM) is used on the server, we will need to be exempt from provisioning.


  • If autodiscovery is enabled and available, we will attempt to use it. Otherwise, we will require the email server connection settings. You will be prompted for this if this is the case.

  • To test your Exchange server's Autodiscovery capabilities, visit this doc: Testing Exchange Autodiscovery.
