How to manually delete e-mail accou?

[Guest whc]

When i was making a new e-mail account in my new S710 (WM6), the phone stalled right when i had written the name of the account. Had to take out the battery and do a HW reset. Went in to mobile outlook egain to make the account again, but now i get the message that another account already exists with that name (the name i also wrote in the before, when the phone stalled), but no e-mail account with that name is to see in mobile outlook.

So here is my question, how do I manually delete the account, where to look in the folder/regdatabase????????
