Recently I was getting the error 0x80030002 STG_E_FILENOTFOUND while trying to run any TRIM 7.3 Outlook Add-In function. The Outlook Add-In had loaded fine and was bringing up all the available TRIM options, it was just when I tried to execute one of the options that it would throw the, oh so very “helpful”, error message as with most COM operations. It wasn’t until I found this thread over in the HP forums that I discovered that Cisco Unified Personal Communicator can interfere with the TRIM Add-In. According to another post any ODMA integration can cause issues with HP TRIM’s Outlook Add-In, in their case it was Novell GroupWise causing the issue.
Fortunately for me, Cisco Unified Personal Communicator was no longer required to be installed (and has been replaced by Jabbr – although I did not test if Jabbr causes issues with TRIM’s Add-In), so to resolve the issue I just had to uninstall Cisco Unified Personal Communicator; for good measure I also did a repair of HP TRIM Microsoft runtimes for VS 2008 and a repair of HP TRIM.
