iCalendar format invite

[mwithheld]

Is this a new feature or enhancement? (required)
New feature

Is this related to a third-party module in Moodle? (required)
No, just local_reminders

Which moodle versions this feature/enhancement can be implemented? (required)
Any

Is your feature request related to a problem? Please describe. (required)
We need invites to be in iCalendar format or have an iCalendar attachment

Describe the solution you'd like (required)
When I create or update an event, the email notification should be in iCalendar format or have an iCalendar-compatible attachment. This would make integration with other calendars (e.g. Google, Outlook, etc) easy for end-users.

Describe alternatives you've considered (optional)

• The Moodle core calendar export as a file is hard to find and use, and does not update with new/changed events.
• The Moodle core calendar export as a URL is hard to find and use, and is limited to the next 60 days.
• Neither sends an email containing an iCalendar invite.

Thanks @mwithheld for requesting this. We currently have a customer with this request as well. Initial ideas/options (not fully investigated yet). Link 1 and Link 2

Probably should be generic enough regardless of SMTP service the Moodle instance use. (We use Sendgrid too, but some customers require their own SMTP service.)

The alternatives described by @mwithheld is what I also investigated today, there's no solution for users currently it seems.
Especially for Zoom or BigBlueButton webinars upcoming in a course and students have no event in their primary/preferred calendar.
