@adam deltinger Should he be using Categories in the calendar event items in order to filter and display them on the separate channel-specific pages? I don't see a mention of this anywhere, so I am curious how you are suggesting the single events calendar gets filtered and displayed properly on each page.
Alternatively, if channel members wanted to sync an entire channel-specific calendar to their Outlook, instead of just copying individual events, you could create separate SharePoint Calendars for each channel. SharePoint calendars allow you to sync them to Outlook.
The default view of these calendars can be added to a Teams tab using the Website option when adding a tab. This way you wouldn't have to worry about creating extra pages and sorting by categories, instead you just create a new calendar for each channel.
The only drawback to this method is that the calendar view is a classic SharePoint view.
I suppose you could try combining my suggestion of a whole calendar per channel plus Adam's suggestion of using the modern events web part on new pages for each channel. When setting up the web part on the page, you would just select the appropriate channel's calendar, and then wouldn't have to worry about the Category field. This way you kind of get the best of both worlds, modern views plus the ability to sync an entire calendar to Outlook if wanted.
