Very slow attachment of PDF file to e-mail

We are having the same exact issues with some users at my company. We're running Lotus Notes 7.02 (yes I know a little old but we're non profit and upgrades come slowly). I've been trying to work with one user's issue and it appears to be pointed solely at Adobe. The problem is that I can't install a previous version due to the requirements of the users needs. I was able to attach multiple documents of items other than Adobe files. I uninstalled adobe and was able to then attach the files that was previously not able to when they didn't have a program associated with them. It's definitely not a virus. I've also gone ahead and uninstalled and reinstalled Lotus Notes from scratch. This all started happening when our company users all started getting pop ups about protected mode (which is the most annoying thing possible). I've looked into multiple other settings within Adobe and still haven't found an answer. I'll continue trying some things and if I find a solution will post it.

I'm having the same problem but not just in Outlook.

Reader 9.x works fine however when you install 10.X and use the attach button within either outlook or Sage to upload a PDF the process either take an extremely long time or crashes the machine.

with outlook you can drag the pdf into the email and it's fine :-s

Believe it or not Reader has very little to do with the attaching of pdf files to the mail program. It passes off the command to the OS which forwards the command to the email program. It could be that you have a virus or other malware slowing the computer down. It could be that you have one or more virus protection programs, which are working but slowing down your machine. There is very little we can do at this end to track down the problem. You could have other programs in the background causing the issue. The first step to determine what is going on is to scan your computer for viruses and other malware to make sure you are running a clean system. If you have no problems in this area, then turn them off temporarily and try to attach a pdf to an email. Does it take any less time?
