Have you tested from various workstation machines? Try having User1 login at Workstation1 and then User1 login at Workstation2. Workstation2 should be a beefier box, with at least 256MB of RAM and a Pentium III ~700MHz processor. And with NO other apps running. Does the problem occur on Workstation2 as well? Also, try opening the user's mailbox from within YOUR profile (or an administrator's profile who has the proper permissions to open the mailbox). See if YOU can open the attachment from YOUR profile on YOUR workstation. This assumes you are not among the ones that are experiencing this problem. Can you right-mouse click and choose 'Save As' on the attachment? If you can, see if you can save it to another box, and see if you can open it then. Or save it to another box, and see if you can open it from another workstation. Is it the same attachment going to multiple people? Or is every case unique? ...just some troubleshooting thoughts....hope they help.

And it doesn't say anything about it being blocked. In fact, there's no error message at all. It just doesn't open. -----Original Message----- From: Chris Wall [mailto:Chris.Wall@xxxxxxxxxxxxxxxxxxx] Sent: Tuesday, January 14, 2003 12:08 PM To: [ExchangeList] Subject: [exchangelist] RE: Email Attachments Won't Open http://www.MSExchange.org/ What version of outlook are you using? There is an 'unlocker' utility I can send for Outlook 2002 if they say they are being blocked.

I searched MS KB and found an article that suggested renaming some dat files. We've tried that but it hasn't helped. Has anyone else experienced this? Does anyone know of a solution for it? TIA Delores
