Experimenting with outlook messages: Unable to get From

I’m experimenting with the outlook message activities and trying to get the emailaddress from the sender. I get the outlookmessages, I loop them, but when I use item.From or item.Sender I get an empty string, when I change it to item.Sender. Address or item.From.Address this exception: 19.10.0-beta.90+Branch.release-v2019.10.0.Sha.ed11515279eee4447b9cc03a899373aa74312c09

The same when I try to acces it through the headers, any idea what wrong?
I succeed in getting the messages, I’ve tried to get the subject and save the attachements of the mails and that worked…

@Daniel_D

For that ForEach loop, have you selected object type as System.Net.Mail.MailMessage or not ?

If not then select it and try once.

Like you can read in my first message, I succeeded in getting the subject and save the attachements, ergo… Yes I did
