Starting this morning, I stopped receiving email alerts for calendar reminders.  I have had this issue many times in the past and MS did somthing on thier side to fix it.  I do not know what.

However, for troubleshooting purposes, I have done:

• Verified that the email reminders is set up on the appointments.
• verified that the default email address for the appointmetns is set.
• I have made no changed.
• No alerts are showing in my junk folder either.

thanks!
