Using New Outlook on Windows for personal email, calendar, and contact management
Since you're using the native iPhone Mail app and Outlook on your Windows PC, it would be helpful to determine whether the issue affects only email synchronization or if changes such as deleting, moving, or reading messages are not appearing across both devices.
As a quick check, you can try:
- Send a test email to your account and confirm whether it appears on both the iPhone and Outlook on your PC.
- Check whether actions performed on one device (for example, marking a message as read or deleting it) are reflected on the other device.
- If the issue affects only one Outlook account, try accessing the same mailbox through Outlook on the web to see if the behavior matches there.
These checks can help identify whether the issue is related to the email account itself or to a specific app/device configuration.
Please let me know:
- Which email provider is affected (Outlook.com, Gmail, Yahoo, etc.).
- Whether new messages fail to sync, or only changes such as delete/move/read status are affected.
- Whether the same issue occurs when accessing the mailbox through Outlook on the web.
With those details, the community can suggest more targeted troubleshooting steps. I look forward to your update and will be happy to assist further.
