Email attachment rename strips out chars

[ntb82]

I am sending a email to a teams space, and when the email and attachment get stored, the attachment has the underscores and dots removed from the filename.     The filename example is process_processid_server.fqdn.csv.    And it ends up as process_processidserverfqdn.csv in the attachments folder.    I would like to keep the original name.  Is that possible?
