how to append data from outlook into excel

case:

I get mails dispatched

this mail has as subject : FW blablabla

in this mail I have in the body the text

mailnummer: 935

I am able to retrieve the subject and mailnummer however I am not able to append this to an excisting excel sheet where already data is present

how do I do this?

at this point it gives me a msgbox with the info cause I don't know how to add this info into an excisting excel sheet with the condition that he has to enter the data on the first empty row that's available

thanks in advance for your help
