Why Am I Getting Duplicate Confirmation Emails for Scheduler?

[smldsllc]

I’m running into an issue with Cal.com where duplicate confirmation emails are being sent out to people who book an event with us. Here’s what’s happening:

• First Email: Comes from our main organizer email ([email protected]), which is set up as the default sender for our events.
• Second Email: Comes from a Cal.com system email ([email protected]), but it has a “Reply-To” that goes back to our main organizer email.

Both emails have nearly the same content, so the person booking the event (the scheduler) ends up receiving two confirmation emails for what looks like the same booking. It’s a bit confusing for them, and I’m trying to avoid this if possible.

Does anyone know:

• Why both emails are being triggered?
• If there’s a way to disable one of these emails—ideally the one from Cal.com—so we don’t end up sending duplicates?

I’d appreciate any insights or suggestions from those who’ve dealt with similar issues! Thanks!

Hey @smldsllc! I'm here to help you with any bugs, questions, or contributions you have. Let's get to the bottom of this duplicate confirmation email issue together!

You are receiving duplicate confirmation emails because the system is not configured to disable the standard confirmation emails for either the host or the attendee. To avoid sending duplicate emails, you can disable these emails by configuring the disableStandardEmails metadata in the event type.

In the handleConfirmation function, there are checks to determine if confirmation emails should be disabled. You need to ensure that the disableStandardEmails metadata is set correctly in your event type configuration. This will prevent the system from sending the standard confirmation emails, thus avoiding duplicates ^[1].

Additionally, there are similar issues reported by others:

1. (bug) Two confirmations when using a shared Microsoft 365 calendar - Open, no comments or solution.
2. [CAL-2970] Outlook sending a second email - Open, suggested solution is to switch off the Cal.com email to prevent duplicate emails.
3. [CAL-2536] [CAL-2534] Double calendar entry/confirmation email in Outlook - Open ^[2][3][4].

@dosu - your instructions seem to be relevant for those who use the Cal API, but that does not apply to me in this instance.

To address the issue of duplicate confirmation emails without using the Cal API, you should check the configuration settings in your Cal.com dashboard or user interface. Specifically, look for options related to email notifications and see if there is a setting to disable system-generated confirmation emails. Unfortunately, I couldn't find specific details in the codebase about disabling these emails through the UI, but it's worth exploring the settings available in your account.

Additionally, ensure that the EMAIL_FROM environment variable is correctly set to your desired sender email address in the .env file. This variable determines the sender email for confirmation emails, which might help in aligning the emails to come from a single source ^[1].

If these steps don't resolve the issue, consider reviewing any team or shared calendar settings that might be causing additional emails to be sent ^[2].
