Thanks for reporting! Given that the data is actually accessible from code (e.g. Log Message), this looks like a display bug in Studio. Having said that, I personally can’t reproduce it on my end.
To figure out what exactly reproduces the issue, could you do us a favor and let us know the following?
Studio version?
Windows or Windows-legacy compatibility?
This is the classic Get Mail activity within Office 365 scope, correct?
Could you screenshot the setup of your scope activity and your Get Mail activity with all properties? (please blur anything sensitive of course)
Thank you! We are tracking this internally. I’ll post an update here when the Studio team has looked at this in more detail. This might take some time though.
