How can I fix the compiler error in MailMessage(0)

Hi All,

I ran my first project and got the error below regarding the MailMessage! It is copied from the tutorial video, so I am not really sure why it’s not working!

Thanks in advance for your help.


Let’s validate whether you received any mail message from the output of get mail activity
Before to that save mail activity where the error is occurring use a writeline activity and mention like this


If the count is more than 0 then you have some mails in that variable
If not let’s check the GET MAIL activity itself

Cheers @Aida_Azar

Can you mention the solution you made so that it would help others
Or if you find the appropriate one in the above comments pls mention as solution



The solution was actually quite simple! I requested to read unread messages only. In my outlook, every time before running the project, I had to mark my email in outlook as unread.
