where do sync email days in ios 16.1.1

Hello mxsinclair,

Thanks for posting in the Apple Support Communities. We're happy to look into this with you. It sounds like your emails aren't loading past the current week. Do we have that right?

Have you tried to search for some of your older emails to see if they are still available, even though you don't see them? If not, give that a try and see if they pull up. Search for email in Mail on iPhone - Apple Support

Search by timeframe

1. Tap the search field of a mailbox list.

2. Enter a timeframe, like “September,” then tap  to see all emails from that timeframe.

To narrow the search, tap the search field again, then enter a keyword, like “meeting.”

You may also want to install any iOS updates that are available to see if that helps. Be sure to create a backup before updating your device, to ensure that your data is safeguarded.
