remove corrupted or missing public folder database from exchange Posted on February 16, 2012 by dpejic I suspected that perhaps some replicas had been missed by the Management Command – but I was running short of time and really needed to remove the Exchange Installation from the Machine so I thought – perhaps I could just remove the reference to the Public Folder from Active Directory. So I broke out my trusty copy of ADSI Edit (which can be downloaded from here) and navigated to the following entry: CN=Folder Hierarchies,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=<Your Organisation>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<your Domain>,DC=<Dot Com> For visual reference it may look the following in ADSI Edit: When I had this key selected the right hand pane of ADSI Edit changed to display the following value: I Right clicked on that value and then chose “Delete” from the context menu. I then navigated to the following key in ADSI Edit: CN=First Storage Group,CN=InformationStore,CN=<Your Server>,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=<Your Organisation>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<your Domain>,DC=<dot Com> Which in terms of a visual representation looks like the following: When I had this key selected I saw the right hand pane of ADSI Edit change to look like the following: I then right clicked on the correct entry for my Public Folder Database and then chose “Delete”. I did this and then using exchange managament console and created a new database. This worked fine!
