SourceOne Email Management - IPM Folder delete is failing during index delete process due to Message Center already being claimed by another Native Archive Server

You attempt to delete folders on an IPM Archive.
The folders remain in the EMC SourceOne Management Console after a deletion attempt - appearing with a red X in the console.  Volume data is deleted from Storage and SQL, indexes appears in deleted state in console.
The following event can be observed in the ExAsIndex.exe.log:

Native Archive Servers that are associated with different Archive databases can't share same storage locations

IPM systems are not archiving new data and require their own Message Center share.
To resolve the issue adjust the Message center location for the IPM Archive.

1. Create a share on the IPM Native Archive server if not already created. Use the install guide to determine the correct permissions for the share.
2. Open the SourceOne Console.
3. Expand the Archive Connection associated with the IPM Archive.
4. Expand the Server Configuration associated with the IPM Data.
5. In the server configuration main pane right click the server name for the IPM Archive and select properties.
6. On the Archive tab click Browse and select the correct Message Center for IPM.
7. Once finished close the properties box.
8. Retry the delete.
