Restore deleted conversation in an Office 365 Group

Hello, all. Just curious if anyone has successfully restored an Office 365 Group Conversation which was deleted by a "regular" user. So far, we have not been able to do this. Here's what we're seeing:

• Conversations deleted from Outlook for PC are permanently deleted (i.e., they do not go into the Group's Deleted Items folder nor the Deleted Items folder of the "deleter").
• Conversations deleted from within the Groups section of the Outlook Web App are permanently deleted (i.e., they do not go into the Group's Deleted Items folder nor the Deleted Items folder of the "deleter").
• Conversations deleted from within the actual Group's mailbox (accessed by using the Add Shared Folder functionality) are moved into the Deleted Items folder of the user who deleted the conversation. Note: you are not actually deleting an entire Conversation this way - you're deleting individual messages. Additionally, when you recover them, they get recovered to the Inbox of the user who deleted the message, not the Inbox of the Group. You then have to move the message to the Group Inbox. After you move the message back, things do seem to sync back up into a Conversation, and it will reappear in the Groups section of Outlook.
• Conversations cannot be deleted from Outlook for Mac.

So what we're seeing is that there is no way to recover a deleted Conversation. I say this because a "regular" user is not going to be accessing the Group using the Add Shared Folder function. They are going to be accessing it using the Groups section within Outlook or OWA.

If we've overlooked something, please let me know - we're excited about Groups but a little nervous about not being able to recover a Conversation.
