I have a recurrent problem.  Since I get pretty absorbed in my job, I use the Reminders function in Outlook for many ridiculously mundane and obvious tasks, like "Go to Lunch" or "Clean Processor" or "Go to Production Meeting" or "Backup Drive 2" or  "Leave!"  (seriously).

I've been using this program in various incarnations for many years.

I set up the reminders to have an alarm go off "0 minutes before" the event, then save them as a series.

It usually works fine for a week or two, then suddenly none of the alarms go off and I've missed the beginning of a meeting or whatever.

I go into the Reminders and every one of them has "Alarm" set to "none."

Outlook never crashes on me, so it's probably not a preference corruption.

I do clean caches or repair permissions on my Mac once in a while, but haven't done it in a few days, and this particular malfunction just happened today.

I already backed up the database, but it would be weird if it defaulted back to "none" from whatever alarms I previously set.

Anybody seen this? and have a solutions?  Thanks in advance!
