When forwarding via outlook the invitation/confirmation email consisting of the default 'registration' button, the receiver will see double buttons.
There is already a feature planned for the future release, which is aimed at solving the problem of double button. (Interactive email layout editor)
Currently there is a simple workaround, which Azavista users can apply to their events. That is by replacing the current button with an uploaded image (e.g a screenshot of the default button) or text.
Please find below the Tutorial on replacing the button with an image:
1. Open the existing invitation/confirmation email template
2. Make a screenshot of the default button from the template
3. Upload your screenshot image replacing the default button
4. Embed a link on the image.
Link Type: URL
Protocol : <other>
URL : %registration_link% -> directs invitees to the registration form page
URL : %event_website_link% -> directs invitees to the meeting details page
