Outlook had been working just fine for me up until a few days ago. Now when
I open the app, a message pops up that says:
"There was a problem reading one or more of your reminders. Some reminders
may not appear. Cannot locate recurrence information for this appointment."

What is so strange is that not a single reminder pops up for the multitude
of appointments I have.

Any suggestions as to how to fix this?

Thanks!
Nancy
