I am working on a confusing issue. I would give all my observations on the issue as below. I m sure our experts would point me on the right direction.
This issue happens with just one user and the user status is bit complicated too.
I have an Exchange Server 2007 and outlook 2007 is the main client. The office environment is Microsoft and the desktop which configures the outlook runs on Windows 7.
At the same time, the user has configured the outlook to his outlook for Mac,I-pad and I-Phone to be used at his home as well. Apart we receive our emails through our BES on blackberry devices.
Outlook is configured to use Cached Exchange mode at Microsoft environment.
There are two emails from a particular user dated couple of months older in the Junk Mail folder of the mail box. The user moves the emails from the Junk Mail to Inbox and can find the emails in the inbox for then. After an hour or so, the emails are back in the Junk Mail folder again.
Please note these are the same emails which are transferred earlier and not new emails arriving to the server.
Steps confirmed as a part of trouble shooting:
1. No rules to mention that these emails should be in Junk Mail Folders. In fact, there is only one rule to deliver the emails from this address to Inbox instead of Junk Mail folder.
2. Junk Mail Filter has been turned off in the outlook.
3. The mail has been declared as "This is not a Junk mail "using the option when it is on Junk Mail Folder.
If it rings a bell for anyone of you and if I missing something important, please feel free to point that to me.
Thankful to your time and efforts as always.
