IOS16 Mail issues

Hello IOS16-Issues,

Thanks for your post to Apple Support Communities. We understand you have some issues with Mail downloading as expected on your iPhone. We want to work together to determine what might be going on. There could be a number of reasons for this issue, we have some questions to help us narrow it down a bit.

1. How many mail accounts do you have configured?
2. Which email provider(s) are you using? (Yahoo, Gmail, etc.)
3. If you use more than one account, does this happen in all of them?
4. Do you get an error stating "unable to download from server"?
5. Does this seem to occur when connected to Wi-Fi or using cellular data?

Next, go to Settings > Mail > Accounts > Fetch New Data. Confirm what is chosen here. We look forward to hearing back from you.

Best regards.

I am having weird issues as well. My phone no longer has a Settings>Mail... Seems to not be coming in since switched to iOS 16. I have Exchange 365 and Gmail. No error messages.
