I am the network admin, and several users are reporting that Outlook 2003 freezes when sending PDF attachments. It started with just one user, but now I have about 10 that are reporting the problem. There could be more, but they are not reporting it. When they send an e-mail with a PDF attachment, the whole machine freezes, and they have to end task until Outlook closes in order to get their machine back. Sometimes they can get it to through after end tasking, but other times, it just won't go without freezing the machine again. I have deleted the Office suite and reinstalled on several of them, and it does not help.
