I should add that I use the Calendar app on my iPhone, my outlook items are visible in the Calendar app, and I have Calendar sync enabled in the Tesla app on my phone.
Has anyone been able to resolve this yet? I am a M3 owner having the same issue - my iCloud calendar will sync but my work email (MS Exchange) will not sync.
