I need to recover deleted emails

Check your trash folder.

When you delete mail, depending on how you configured the account when you set it up on the iPhone, it will either go to the Trash folder, or the Archive folder. If you have the Trash folder set to delete after a certain amount of time, then they will get permanently deleted.

As I indicated, deleted mail is sent to Trash. If you deleted it from Trash, then it is gone.

Is their any way i could recover deleted mail
