we are using a versioning history in an email enabled library.
When a user send an email with an attachment (e.g. test.doc), the attachment will automatically
visible in the library (test). So far so good.
But when the user edit the (his) document and send again an email
with the same named (changed content only) attachment to the library, it
appears a second, different thread in the library and the name of the
attachment you can see in the library is changed to "test 1234'.
Is it possible to avoid this and the existing document will be updated (versioning history)?
