Zoho CRM integrates with Microsoft 365 (formerly Office 365) to synchronise contacts, tasks, calendar events, and chat conversations between the two platforms, so your team isn't manually duplicating data or switching apps constantly.

What it covers

• Two-way contact and task sync between Zoho CRM and Microsoft 365
• Calendar event synchronisation, so meetings created in either platform appear in both
• CRM dashboards and shareable records available directly inside Microsoft Teams for extra context during chats
• Customisable or automatic field mapping between the two systems

Setting it up

In Zoho CRM, go to Marketplace, then Microsoft, to install and configure the integration. Initial calendar sync brings across a maximum of 5,000 events, prioritising future-dated events first, followed by recently closed ones. Events originally brought in through an import won't sync, but events created individually in Zoho CRM, or updated in bulk via mass update, will.

Known limitations worth knowing before you rely on it

• A separate sync calendar. The integration typically requires maintaining a dedicated Zoho sync calendar in Microsoft 365 alongside your primary calendar, rather than syncing directly into your main calendar, which some users find adds extra manual copying between the two.
• Calls and appointments aren't fully supported. Zoho has acknowledged that Microsoft 365 doesn't support Calls and Appointments the same way Zoho CRM does internally, so these activity types don't always translate cleanly between the two systems.
• Occasional sync reliability issues. Duplicate events and recurring events breaking unpredictably have been reported by users of this integration, so it's worth spot-checking your calendar periodically rather than assuming every sync completed cleanly.
• New contacts don't auto-create from unknown senders. A CRM task can't be created from an email sent by someone who isn't already a Contact in your system, so a promising new inbound enquiry still needs a contact record created manually before it can become a follow-up task.

Turning it off

In Zoho CRM, go to Marketplace, then Microsoft, and click Disable in the Events section, or alternatively delete the Zoho CRM calendar directly from your Microsoft 365 account. Either way, previously synced events are removed from Microsoft 365 once disabled.
