Troubleshooting IMAP to send email in ClickUp

  • Updated

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.
Here's an example on generating an Outlook app password:
1) Navigate to Microsoft's security page here
2) Select Get started under Advanced Security options:

3) Next, select create a new app password as seen below:

4) Once your app password is generated, enter it into the password section of your 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.
