The EPMOfficeClient can be found in your local directory. The easiest way to find this is to open Windows
Explorer and type in %temp%, then go up one level.
Within this directory, you will find a directory for the downloaded metadata (Metadata). Each directory is a
connection to a model/cube.
To delete the metadata, simply delete these directories
Another way to clear the metadata is via the EPM Add-in. Simply navigate to More->
there is functionality to refresh Metadata for the current connection meaning the
user will not have to log out of the EPM Add-in in order to refresh the metadata. This functionality can
be found at More -> Refresh Metadata for Current Connection.
