Outlook 2007 Windows 8.1 I had a corrupt recurring reminder that appeared in the reminders window every time outlook 2007 opened. I couldn't see it or delete it in the calendar. I removed it using MFCMAPI download following instructions on the net. I deleted the reminders folders in the root file. All my calendar items are still there. I don't know if it's fixed as now I have no reminders coming up at all. I've done Cleanreminders, cleanbusyreminders & Resetfolders. Reminders is turned on. Can I insert the outlook 2007 disk and install overtop of the existing program? Will I lose my contacts or messages? Nothing helps.
