In Planner, I added a few comments to a task. The first time I added a comment, an email was sent to the groups mailbox. I subsequently added a few more comments to the planner and the mail item in the groups mailbox tallied, as it to include all the comments in one item. I then deleted the email from my groups mailbox and as a result all the comments were also removed from the task in Planner. This was NOT what I expected to happen. Can others affirm this is what happens? How can you manage the groups mailbox, if you are not able to move the mail items to subfolders like other mailboxes? I thought be deleting the email, the comments would remain. Any help or supporting documentation you can provide would be helpful!
