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…


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
