Cannot rename Reminders List in iCal for Exchange Task List

Question

I figured out that Exchange Tasks show up in OS X Lion as a Reminder List in iCal.  When I create a new Reminders List in iCal using File > New Reminder List > Exchange, it creates a new list with the name Untitled in the Reminders pane of iCal.  I can then rename the new (Untitled) list that I created by selecting the corresponding Reminders List from the Reminders drop-down and double-clicking over the Untitled name to rename it.  It seems that iCal successfully renames the Reminder List, but once it syncronizes with the Exchange Server, the Reminder List that I just renamed changes back to Untitled. Has anyone else experienced this issue and/or found a solution?  I don't always have the ability to log into Windows and would like to have the functionality to manage my Reminders Lists from my Mac.

Answer 1

This worked for me:
The Problem: I also had the problem where I couldn't create a Reminder List having the same title as a Calendar List.  At one point I think I had the title of "Work" as both a Reminder and Calendar List, then when I deleted it from the Reminder List, it wouldn't allow me to create it again, and would go to Untitled.
The Solution (try at your own risk!):
(1) Backup the Calendar that has the same name.  Select the Calendar by clicking the Calendar button in the top left and click on the calendar.  Go File menu -> Export -> Export... .   It should show your calendar name with ".ics" at the end, save this somewhere.
(2) Delete the Calendar: Click the Calendar button in the top left and right-click on the calendar, choose delete.
(3) Create the new Reminder list with the name that you want.  It should now allow you to.
(4) Import the calendar you backed up in step 1.  Go File menu -> Import -> Import... and choose the .ics file you backed up. I've done this last step in the past but not this time around since I actually didn't care for the calendar to come back, so I don't remember the exact process after here.  I think it either gives you an opportunity to merge the events of the ics file into an existing calendar, or you can create a new calendar for the importing events.  If it doesn't give you this second choice, then first create a calendar with the name you want, select it, and start the import process over again.
Hope this helps!
