Just a request. When you share an "error message" be sure to post it without edit. You have a great clue in the error message but since I can't guess which error it was, try this. At google type that error message in "quotes".
You may get lucky,
I've been using Outlook for years now, currently on 2007 version,
Today I've come across a problem I've never seen before. This morning an appointment reminder popped up on time as usual, and as I no longer needed it I clicked on Dismiss, thinking this would be the end of it...But then next time I opened Outlook, the reminder popped up again. Again I ?Dismissed? it, but again it reappeared.
I then went to look for it on the calendar to delete it, but there was no sign of the appointment at all. So next time it popped up I clicked on snooze to remind me again in 5 minutes, but got an error saying that it could not be reset as the appointment could not be found.
So now I?m stuck with a reminder for an appointment that can?t be deleted because it doesn?t exist!!
Has anybody out there had a similar problem, and if so, how was it resolved?
