Exchange 2007 on Win2008. ONLY SOME users (in small 25 user network), incoming messages have = sign inserted in entire message. Even in signature. Signature seems to have = in the same spot for every email?! Mostly have the = sign followed by a space dispersed throughout the message. Doesn't matter if viewed in OWA or Outlook. After searching web, I see another user on Google has same problem, but can't find resolve!
