I am about to lose my marbles, here. I've tried everything I can think of and the various suggestions on several lists and newsgroups and no joy. Running exchange 2003 enterprise trial, there was some mixup with the licence order and we couldn't wait for it to be resolved. Ex2k3 is running on a Win2k3 member server in a Windows 2000 domain. All email received direct into the exchange server after the import of old email is fine, some older stuff has issues. Here is the summary of where I am at. Basically old email that's been imported into Exchange 2003 has a small percentage that consistently but randomly (same message has the problem each time, just can't find any correlation between the message type or who it came from) is unreadable. It is unreadable in Outlook 2000sp3 (the default in this office), Outlook 2003, no sp, sp1 or sp2 and OWA. The errors are: When you click on one of these messages, the preview pane says This item contains active content and cannot be displayed in the preview pane, open the item to read it's content If you double click the item in folder list view, a popup says Can't open this item, the operation failed In owa, the listed error for the same message is 501/505 not implemented This happens both to messages that have attachments and ones that don't. If we delete a folder on the exchange side and copy/paste the same folder from the pst file, same problem occurs with the same messages. When the same message is viewed in outlook from within the pst file, there are no issues viewing the message. I've tried the oulook import procedure, the drag and drop procedure from the pst to the exchange mailbox, used exmerge and even imported from outlook express (file export in OE), same issue with all the mailboxes. Of the 45 users or so that were imported, 2 are not having any problems, in both cases they had only a small amount of mail in their respective pst files. The last item I can think to try is upgrading the Exchange server to SP2. I hope to do that tonight. Lastly, if I upgrade to SP2, when the license order arrives and I do the reinstall to convert from trial to full version, assuming the cd I get does not have SP2 already as part of it, what do folks recommend? -- Harondel J.
