Restore deleted conversation in an Office 365 Group
Yeah, we've been trying to get the Group folks to realize that exposing some additional folders for Groups is a must... Anyway, to answer your question, yes, it is possible, but you have to resort to some workarounds. The easier one is to open the Group mailbox via the OWA "add shared folder" functionality - it will expose all the Group folders and you will be able to drag/drop or move the conversation out of Deleted items.
Another method is to do it via tools such as the EWSEditor: https://blogs.technet.microsoft.com/exovoice/2017/04/26/recover-deleted-items-from-a-group-mailbox-in-office-365/

Just getting frustrated with this....... I deleted several messages in an O365 group and cannot find anyway to restore them. Although when I look at the group mailbox statistics, I can see that the deleted item count goes up so the deleted messages are getting logged somewhere. I have gone through adding the mailbox as a shared folder in OWA but the deleted items folder shows up as empty. Anyone have any idea how to restore these please?
If they are not in the "deleted items" folder, you will have to check the "recover deleted items" and in general, follow the normal process of recovering items in Exchange.
