Troubleshooting "Cannot join team" error with email mismatch
Last updated: July 17, 2026
If you're seeing a "Cannot join team" error with the message "User and invitation emails do not match," this indicates that the email address used to send the team invitation doesn't exactly match the email address of the logged-in user.
Solution
The most common cause of this error is a case sensitivity mismatch between the invitation email and the user's login email. To resolve this:
Check the exact email address that was used to send the team invitation
Compare it with the email address the user is logged in with
Look for differences in capitalization (e.g., "Thomas.middel@company.com" vs "thomas.middel@company.com")
Resend the team invitation using the exact email address format that matches the user's login credentials
Important Notes
Email addresses are case-sensitive for team invitations. Even small differences like capitalization in the name portion of the email address can cause this error. Make sure the invitation email exactly matches the user's registered email address, including proper capitalization.
If you continue to experience issues after verifying the email addresses match exactly, please contact support for further assistance.
