iPhone Mail doesn't sync IMAP messages

Hey Julius N,

Sounds like your mail account isn't syncing between devices the way you'd expect them to.

To clarify, does your inbox show that it's fully updated on both devices after reading the email on one of your devices? Also, since syncing is disabled when Low Power Mode is enabled, be sure this feature is turned off on your iPhone to ensure it's syncs correctly.

If you continue to have issues, be certain you're connected to a reliable network. If you're currently experiencing this over Wi-FI, test over cellular.

Lastly, since this is an IMAP account, you can safely remove the account and add it back without losing any emails. To delete it, go to Settings > Mail > Accounts > tap on the account you want to delete and choose "Delete Account".

Add it back again using these steps: Add an email account to your iPhone, iPad, or iPod touch

We hope this information helps out!

Take care.

Julius N,

Thanks for the update! We're happy to hear that things are working better for you after removing the account and setting it back up again.

Cheers!

Julius N,

Mail absolutely supports IMAP accounts. This behavior typically occurs when there's a network interruption or an issue with your account details. So those are the best places to look to resolve your issue. Check that both devices have a strong network connection, check to be certain your iPhone isn't in Low Power Mode, try refreshing your inbox by pulling down from the top of the inbox.

With the account being IMAP, the emails aren't downloaded off the server onto your iPhone, therefore it's always safe to delete these accounts and add them back when you experience a problem.

If you continue to have issues after doing so, we recommend working with the email provider for more help from here.

Take care!
