The connector did not get registered correctly. There's a way to find the version, but this connector isn't much good if it's not registered correctly.
To find the version, you can go to Program Files\Common Files\System\MSMAPI\<locale-id>. For US that's 1033, but it would be some number. There should be a bunch of files in that directory starting with LSMS. To find the version, right click on one of those files, then Properties, Version, File Version.
To try to get this connector registered properly, go to this same directory and execute the following commands:
regsvr32 /u /s LSMSSP32.dll
regsvr32 /s LSMSSP32.dll
regsvr32 /u /s SharingAddin.dll
regsvr32 /s SharingAddin.dll
regsvr32 /u /s ShutdownAddin.dll
regsvr32 /s ShutdownAddin.dll |
