Several weeks ago, I created an archive (.pst) file where I'm archiving my conversations in Lync. After creating the archive (.pst file), I archived my conversations in a folder named "Conversation History" (old). Today, I
tried to archive my conversation history for the last two weeks. In my mailbox, all my current (last 2 weeks) conversations were saved in a folder also named "Conversation History" (new). I carelessly dragged the "Conversation History"
(new) folder to the archive (.pst file). Then I realized that the new and the old folders share the same name. I thought that the new folder will overwrite the old one, but its the other way around. After I checked the archive file, only one "Conversation
History" folder was in it, and its was the old one. Now I'm searching for a way on how can I recover the new folder that was lost. I tried "Undo" but i didn't worked. I tried searching on the deleted items but it wasn't there. I tried recovering
deleted items, but also, i wasn't there. I'm hoping that there is anyone out there that could help me. Thanks!
