I am trying to get my iCloud calendar and contacts synced from my phone to Outlook on my desk top PCs (I have 3).

To sync iCloud calendar and contacts from an iPhone to Classic Outlook on multiple desktop PCs, use iCloud for Windows on each PC.

1. Install iCloud for Windows on each desktop PC.
2. Open the iCloud app and sign in with the same Apple ID used on the iPhone.
3. In the iCloud app, select Contacts and Calendars and then choose Apply.
4. Open Outlook on each PC after setup finishes.

After that, the iCloud calendars and contacts should synchronize with Outlook on those PCs.

If the iPhone events are only in the device calendar and not in iCloud, they must first be synced to the iCloud account. Outlook only shows calendar events that come from an account added or synced to Outlook.

If sync does not work in Outlook mobile, Microsoft’s documented reset path is:

• Outlook app Settings > tap the account that is not syncing > Reset Account
• If needed, delete and re-add the account

If the goal is Outlook on Windows only, the primary setup is still iCloud for Windows.
