Not sure if my posting helps or not.If the object that you are reporting needs to come in as subtype 749 the email subtype then your options are
1)Extend OOB WSAPI using Oscript by defining the logic in Oscript.Not an easy avenue if you are new to livelink and oscript.
2)You can install the Enterprise Connect plugin form OT and manually play with how a drag and drop mail works,then you can create a addin using word or excel VBA.OT has documenetation that shows how cliett SDK programming is done via EC.I don't know how it is done but there are lots of people posting in the KB saying they added this menu item and that menu item.
3)You can use the old lapi binaries.I beleive it supported email because that is how email management from OT used to work.It is quite possible since lapi is deprecated the ot email managment program is now using WSAPI.You could ask them nicely or see if there are public api's.
4)Personally I would opt for Object Importer by writing an extension.....
Well, if I called the wrong number, why did you answer the phone?
