How can I use ZOOM email and ZOOM calendar to send email invites for ZOOM meetings?

[rts1]

I don't have gmail (free nor paid) or o365 (free nor paid). I use a regular IMAP email service.

Here is a KB I tried without success: https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0063688

I purchased zoom because of the features below:

What are Zoom Mail and Calendar?

The Zoom Mail and Calendar Clients allow you to view and manage your emails, as well as schedule and manage your calendar events, directly from the Zoom desktop client, further centralizing all your meeting, phone, chat, whiteboard, email, and calendar needs in one application.

HOW?

I signed up 2 months ago (monthly pro plan) and I still do not have an answer after multiple tickets and "support" chats. You may be able to pay to get to a human, but they just copy and paste KB articles.

I went to webex, created a free account, made a test meeting:

• No additional email account needed
• Invites are sent without additional configuration
• No google/o356/zmail/etc needed
• Attached .ics files automatically

Zoom cancelled.
