Outlook Error: could not open one or more attachments
Posted on 2004-10-13
Using outlook 2000 sp-3 I am no longer able to send any attachments without receiving the message "could not open one or more attachments"
After acknowledging this error msg the mail goes out with attachment, but it's very inconvenient.
I checked the knowledgebase and followed the suggestion to change security settings, but to no avail. (it's standard 'medium' now). I don't have a virusscanner installed and it does not matter which extension or size the attachments have. I'm completely sure I have no virus on my pc.
Originally I also had a problem receving attachments (a message came up that I was out of memory when viewing incoming messages in the preview pane), but after reinstalling outlook 2000 from scratch this disappeared for a few days. However afterwards it was just the way it was before. The problem with outgoing attachments stayed after the reinstall.
A second (related?) problem is that a new rule I made in Outlook (to forward all mail addressed from one mail address to another one) fails after sending about 10 to 20 messages due to it being 'out of resources'
I'm running XP sp2, but the problem was already there with SP1. The problem didn't always exist; it just popped up after about a year on this pc. My *.pst file is fairly large (almost 500mb)
I'm at a loss for an answer as neither the microsoft knowledgebase nor google come up with a satisfying link. Most point to problems with virusscanners.
