Thanks for the reply Donna, I had tried unzupping the solution and searching for the Guid but it wasnt found, nice tip about the metadata browser I never thought of that assuming it lets you search but metadataguidId.
I will give that a try and post back my findings.
Strange, using the metadatabrowser the component is still not found, we currently have an issue importing our solution anyway due to an issue with mailboxtrackingfolder entity missing. Microsoft are looking into this currently, the solution was to
manually remove them relationships for the time being by editing the xml file, which was working for a while, however, I am now certain these to issues are linked.
Thanks again for pointing me at the metadatabrowser.
