  1. I have this problem, but the solution yoiu gave didn’t fix the issue… still have access denied opening attachments :( I have outlook 2007

  2. Great, worked perfectly!

  3. works perfectly with office XP/2002

  4. Worked perfectly in Outlook 2007 as well. However, is there a way to increase the folder’s size limit so this issue isn’t encountered or seen as frequently?

  5. Jmbronk,

    That is a really good question and one I never thought of investigating. I will see if the size limit on the Outlook temporary files folder can be changed. When I find an answer I will let everyone know. Again, good question.

  6. I am a bit of a noice at this, but this advice was the best, as even i could understand it.

    Thanks
