I have a user that was recently upgraded to Lotus Notes 8 from Lotus Notes 6.5. When she receives meeting invites with attachments (Word or Excel) and attempts to accept meeting invite she gets the following message "invalid or nonexistent document". She can click ok to the error message and she can open and view the attachments. At the moment she is the only person this is happening to. Has anyone seen this problem before and what was the fix for it? Thanks for your help.
