I have an email account that requires CalDav Synchronizer to access the calendar of this email account.

In the old Outlook, I easily installed the CalDav add-in. However, after switching to the new Outlook, I lost this calendar.

When I try to install CalDav, it does not appear as available in the new Outlook. Additionally, it does not show up in the "My Add-ins" dropdown menu.

How can I fix this?

    Hi @Luiz_Fernando

    Welcome to our forum!

    New Outlook still has limited support for third-party add-ins. More information, see: Feature comparison between new Outlook and classic Outlook - Microsoft Support

    By the way, Outlook actually has an official feedback portal where customers can send feature requests or suggestions to the product team. It is recommended that you could post the functions you expect and your sincere suggestions on the website dedicated to collecting feedback. We sincerely welcome your suggestions, and thanks for your understanding and support!
