iCloud, Google and Outlook in one view
The problem is rarely that any one calendar is bad. It is that you have three of them and only one week.
What most people assume
That keeping work and personal calendars in separate apps is a boundary rather than a bug.
The double-booking is structural
If your commitments live in three places, no single place can tell you whether you are free. You are the merge step, and you run it from memory, usually while somebody is waiting for an answer.
This is why the classic failure is not forgetting an event; it is agreeing to something that collides with an event you could not see.
What one grid gives you
Every account on the same week, colour-coded by origin, editable in place. You stop asking which app has the answer, because the question stops having a plural.
The separation people actually want is visual, not structural. Seeing work in one colour and family in another gives you the boundary without giving up the overview.
Where the tiers sit
iCloud and Google both sync on the free tier. Microsoft accounts — Outlook and Exchange — sit in the paid tier, because that connection carries a running cost that the others do not.
If your work calendar is Google, you will never need to pay for sync at all.

| Monthly cost of adding Microsoft, in dollars | 4.99 |
What it looks like
What to do
- Add the personal account first, then the one that causes the collisions.
- Colour by account rather than by category — origin is what you need at a glance.
- Keep writing to whichever calendar the other people involved already read.
