Sync calendar with CRM

My calendar and CRM are out of sync; I need every sales meeting and customer call to appear on contact records. Sync my Google calendar with the CRM so meetings created in either place show on the contact timeline, set event visibility to team only, and make sure duplicate meetings are merged. Do a quick scan for missing-timezone mappings and report any events that fail to sync.

Before I connect calendars for the sales team, make it obvious to a reviewer what matters: surface where meetings will appear on the contact timeline, call out which event types won’t sync, and highlight timezone and duplicate rules that cause missing or doubled entries. Flag the one or two settings a non-technical marketer would change by mistake and suggest the safer defaults.

I turned calendar sync on for my account and many Q2 meetings never showed up in the contact timelines. The sales reps use different timezones and some events were created in a shared calendar. I’m worried the sync missed recurring events or merged wrong ones. What’s the most likely cause, what should I check first, and what immediate fix will restore those missing events without creating duplicates?

Every month we spend a day re-syncing calendars for new reps and fixing duplicates on contact timelines. I want to stop firefighting. Which one habit change or setting (calendar default organizer, timezone enforcement, or a single shared team calendar) will cut our time spent reconciling by at least 70% and what rollout steps make that stick?
