How to get birthdays to show in outlook calendar. They are on iphone calendar.

maurie sandler 0

Birthdays used to show in both my iphone 16 and outlook calendar. Now just iphone calendar. Looks like the borthdays on the phone are pulled from my contact list by siri??? I have done the AI search and tried their suggestions but still not working. Seems that it stopped in one of the recent updates. If any one has their iphone calendar and windows 11 pc outlook calendar birthdays synced please let me know how you did it. I had apple on the phone for over an hour and still not fixed. Thanks

Birthdays on the iPhone calendar do not automatically appear in Outlook for Windows unless those birthdays come from an account that Outlook can sync. If the birthdays are only in the iPhone calendar, Outlook will not show them just because they exist on the phone.

Key point:

IMAP and POP do not sync calendar or contacts.
For birthdays to appear in Outlook, the birthday data must be stored in contacts or calendars tied to a synced account.

Try this end-to-end check:

In Outlook on the web or Outlook.com, open Calendar.
Go to Add calendar > Birthdays.
Select the correct account and turn on Turn on the birthday calendar.
In My calendars, make sure Birthdays is selected.
Wait a few hours if needed, because birthdays from contacts can take time to appear.

Then verify the source data:

Open People/Contacts for the same Outlook account.
Check whether the affected contacts still have a saved Birthday field.
If a birthday is missing from the contact, add it again and save.

If birthdays previously showed and then stopped:

Turn the Birthday calendar off and back on again from Add calendar > Birthdays.
If needed, re-add the affected contacts’ birthday information. A reported fix was deleting and adding the Birthdays calendar again, then deleting and adding the contacts that were not showing.

Important limitation:

If the birthdays are being shown only by the iPhone calendar from Apple-side contact/calendar data, Outlook on Windows will not mirror that unless that same data is synced through an account Outlook supports.
In the Outlook mobile sync guidance, device calendar events appear in Outlook only when they are added through an account that has been synced to Outlook.

If some birthday entries included extra notes or custom details, use a normal yearly recurring event in the main Outlook calendar instead of relying only on the Birthday calendar.

Hi maurie sandler,

That sounds really frustrating, especially since this worked before and you have already spent over an hour trying to resolve it.

Because the birthdays are still visible on the iPhone, I would first check whether they are coming from iCloud rather than from the Microsoft account used in Outlook.

Could you please confirm the following?

Are the affected contacts saved under iCloud or On My iPhone?
Is iCloud for Windows currently installed on the Windows 11 PC?
In Classic Outlook, do you still see any iCloud calendars or contacts?

If the contacts are stored in iCloud, open iCloud for Windows, make sure Contacts and Calendars is enabled, and select Apply. Then close and reopen Classic Outlook.

You can also sign in to iCloud.com and check whether the same contacts and birthdays appear there. If they appear on the iPhone but not on iCloud.com, the information may be stored only on the phone and would not be available for Outlook to sync.

If iCloud for Windows is already configured correctly but the iCloud calendar has disappeared from Outlook, please let me know whether Outlook shows any error or whether the entire iCloud section is missing. That will help determine whether the issue is with the contact data or the connection between iCloud and Classic Outlook. Thank you so much for your understanding.
