Would love to be of more help but the only thing I know is that you have just one "normal" calendar. It is visible in the folder list of outlook. I realy can not imagine how you could have 2 calendars there.



The "my calendars" big option in outlook can list all sorts of calendars indeed but right clicking those should give a remove option as well.

After completing the backup I followed your earlier suggestion to copy/paste the contents of Calendar (2) into the empty Calendar file. At that point, I was able to move the two instances into the expected locations: "Calendar (2)" down to My Calendars and "Calendar" up to [main] Calendar.

I will wait a few days to make sure new appointments appear in the right instance and then delete Calendar (2).

Thanks for your help in solving this annoying problem!
