Step-by-Step Fix
1
Reset Mail and Calendar App
They are bundled together; resetting one resets both.
2
Re-add Account
Remove your Google/Outlook account and add it back.
3
Check System Time
Syncing will fail if your clock is off by more than a few minutes.
When to See a Technician
The Calendar app relies on the "Background Intelligent Transfer Service" (BITS).
