Hi, I have a strange problem with one Unity mail box. Caller (checked record message), use option one to save)left new message in the mail box. However, when mail box owner opens the box, the box is empty. I also deleted the mail box (including active directory and mail box in Unity) and re-created a new box (under the same name/id) but could not resolve the problem. Other mail boxes in the same server are working as normal. I also create some new id and they are all working fine. Have you experienced the same problem and resolved the issue? What is the process to check which component is going wrong in Unity.
