Mailserver subfolders not shown on iPhone mail app

iPhone 14 pro max ios 17.1.2


I configured a mail account in Exchange mode (however provider mailserver has nothing to do with Microsoft or Microsoft account)

All works fine but mail subfolder are not shown on iPhone mail app.

Sync is configured in Push mode, and into Push configuration , desired subfolders ARE SHOWN and ticked !

I rebooted iPhone, deleted and riconfigured mail account, deleted and riconfigured mail account IN IMAP MODE, nothing , no way to make app to create/display subfolder.


Of course, all is displayed correctly in other non-Apple devices, other mail browsers, including Outlook itself, linux appliances etc.


Any further serious suggestions other than "restart your phone" or " reconfigure your account" ??


Thank you

Thank you for suggestion , already tried all of these without success.


Anyway I got it working casually this way :


In mail app I added a new arbitrary mailbox (folder) into wanted account (app->top right "edit") , saved, et voila' , the desired undisplayed folders came out .

Then I removed the extra folder manually created.


Hope this helps...

Remove your email account and set it up again

Make sure that all of your emails are there or make sure that your email is saved somewhere other than your device. On your device, go to Settings > Mail, then tap Accounts. Tap the email account that you want to remove. Tap Delete Account.
