can't reply to inbox e-mails on iphone 14

Hi there,

Thank you for your reply,

I get told it can't be sent as the password on that particular A/C is incorrect & offers to take me to settings. To my best knowledge I have never changed the password on this & even the character dots are the correct amount for the password but it won't have it.

I must confess before going further I'm not entirely computer savvy but I've never had any problems before completing simple communications etc.
