Outlook 2003, Could not complete the operation. One or more parameter values are not valid.

I ran into an issue today with an Outlook 2003 user that could not perform the Print or Reply All actions on any message received. If I attempted to perform those actions I would receive the following message : “Could not complete the operation. One or more parameter values are not valid.”

I search Google and found some information for resolutions with this error coming up when a user tries to Create or Update a Task. My issue is related to Printing or Replying to All from the message window.

Here are the steps I took to resolve the issue, although it was not monumental, it seemed to resolve the issue.

1. Tools > Options, Mail Format tab
2. Change option; “Compose in this message format:” to Plain Text from HTML.
3. Change option; remove check boxes for using Microsoft Office Word 2003 to edit messages.
4. Disable signatures for both new messages and replies/forwards.
5. Click Ok, try Reply All or Print, it should now work.
6. Reverse the settings back to the way they were.
