When you are using groups in outlook all seems nice ... but I have the following situation:
"All conversations from a group can't be read in a pop-out window ... "
For a regular message you can use the double-click to open it in a seperate window ...
Question: Why is that not possible for a conversation in a group??
Agreed this is quite annoying if you use the converstation view.
As a work around you can enable the Reading Pane and then click through the emails and they show in the Reading Pane section.
Indeed a work around but .... if you change that it also changed for the regular/normal mails ...So I really think & hope that MS should fix this ....
You should post this on the UserVoice page: https://office365.uservoice.com/forums/286611-office-365-groups
