Natively supporting HTML markup in meeting request bodies is not possible (see
KC-114). There might be opportunities to treat .ics attachments with an HTML body different when displaying.
This creates a dependency on the import/export of ICS files and a modification of the frontend to treat these files differently (e.g. sanitize them, XSS protection and show the body).
- HTML formatting of a meeting request sent from OL is preserved.
- WebApp/DeskApp just others plaintext to comment in calendar items / tasks
