Hi ​@Kaisen - Thanks for reaching out!

Would you be able to create a test event and send us a screenshot of what that confirmation looks like? Do you also see this event created in Calendly as well?

let me know! Any information you can give me on this would be super helpful.

Hi David,

thanks for getting back to me.

The problem was an issue with outlook, which I could fix by myself- now everything works.

Another question. When a customer get an Invitation message “via calendly” is vanished. Do you have an idea how we can put back to the message?

Hi ​@Kai73316.

In this case, I believe this is removed when you turn off Branding in your account. If you turn the Branding back on, “Via Calendly” should be added back! You can do this from this page here: https://calendly.com/app/personal/branding

Let me know if you have any questions.
