If you recalled my post from a few days ago where I have a folder which mysteriously became “invisible”, well there is a fix! Thanks to some of my friends at the mother ship (read Microsoft) in helping out with this – they know who they are and do not need to be named here.
One thing before you continue to the steps below, ensure you are connected to Exchange and logged in to Outlook. As always you can click on the images to see them in full size.
- Download MfcMapi – also known as the Microsoft Exchange Server MAPI Editor. If you are like and never heard of this tool it is very impressive. I think the Exchange support guys use this and is fairly well known by then.
- From the ‘Session’ menu, choose Logon and ‘Display Store Table’.
- You will be asked to pick a profile first.
- Double-click the store that contains the hidden folder. In my case this store was Exchange and you can see I have the “Mailbox – Amit Bahree” store selected.
- Expand the ‘Root Container’ of the store, navigate to the hidden folder and select it. Please note that your visible folder hierarchy is contained in a sub-folder of the ‘Root Container’ that is likely named ‘IPM_SUBTREE’ or ‘Top of Information Store’. This again in my case is “Gadgets”.
- Right-click the PR_ATTR_HIDDEN (tag 0x10F4000B) property in the property list of the hidden folder and choose ‘Edit Property’ from the menu.
- Disable the ‘Boolean’ check box and press OK.
- Select File | Exit to close the current window. From the Main window, select ‘Logoff’ from the ‘Session’ menu, and then Exit MFCMapi.
There is also a KB Article (924226) from Microsoft which seems to be similar, although that talks about Contacts specifically the steps are the same. The cause as per the KB article is the improperly formatting the Provisioning registry keys for OWA on the Back-End (mailbox) Exchange Server.
