iPhone mail not syncing since last update
Since the last update for computer and iPhone, my emails are not syncing between my computer and my iPhone. What do I need to do?
Email does not sync device to device; it syncs from the device to the email server, and from the email server to other devices. So start your troubleshooting with mail sync to the email server. If your email provider has a web interface see if your devices are syncing to the server. The iCloud server is https://icloud.com/mail. For other mail accounts it is usually webmail.<email provider>.com/net/org, etc.
