One calendar view when you run several companies
Every new company comes with a new Google Workspace or Microsoft 365 account, and a new calendar that knows nothing about the others. Here's how to keep them all in step.
Updated November 11, 2026
The problem
Each company's team books you into its own calendar. Company A can't see that Company B has you in a board meeting, and neither can see your personal life. The more companies, the more often two of them claim the same hour.
What people try first
- Checking every calendar before saying yes. Works until someone else books you directly.
- Copying meetings across as "Busy" by hand. Every move and cancellation has to be copied too.
- Sharing calendars between accounts. Lets you see them together, but colleagues in each company still see you as free, and sharing across companies is often restricted.
What works
Connect every company's calendar to Syncydo. Whenever you're booked in one, Syncydo adds a hold to all the others, so each company sees you're busy without seeing anything about the others.
- Each company sees only Busy. Board meetings, investor calls and other clients stay private. On Plus you can show the calendar's name instead, like "Company B", if you'd rather.
- Clashes flagged. When two companies' meetings overlap, Syncydo points it out so you can move one early.
- Per-calendar switches. Decide which calendars block the others and which receive holds.
- Google, Microsoft 365 and Zoho in any mix, plus the calendars on your iPhone.
- One view with a Join button on every call, whichever company sent it.
Free covers two calendars. Plus covers five and Pro covers ten, for when the companies keep coming.
Questions
Will one company see another company's meeting titles?
No. Holds say Busy unless you choose otherwise.
One of my companies uses Microsoft 365 and needs IT approval for apps.
Send its admin syncydo.com/it-admins: they can approve Syncydo for that company in one step.
How many companies can I connect?
Up to 10 calendars on Pro. A calendar is any one you choose to sync, from any of your accounts.
