How I fixed my problems with Outlook Sync

Question

This is a repost into its own thread.
Well, I finally got the Calendar in Outlook 2007 to sync properly!
I have Win XP with Office 2007. Using the latest versions of iTunes and firmware.
It seems there must have been something corrupt within the Calendar, in the .pst file. Not sure what but the more I thought about that .pst file, I have been using it for many years and continually moving it to my next system or software version. So, who knows what junk there may be hidden in it.
Despite the fact that I deleted just about all of the entries in the Calendar and just kept the ones from the last month. Still did not work.
Plan A
Go into Outlook and print out your calendar, as far as necessary. Unfortunately, you will have to rebuild your calendar manually. The calendar printout will assist in recalling the date, time and purpose, etc. When I did mine, I simply worried about upcoming appointments and therefore, it was not a big issue. I later added holidays in Outlook, using the holiday add function and that worked fine and sync’d ok.
Go to your .pst file. If it is in its default location it will be C:\Documents and Settings\User Name\Local Settings\Application Data\Microsoft\Outlook.
I copied the original .pst file and made a duplicate copy and left them in their original directory. Then I renamed both files, to oldoutlook.ddd and oldoutlook1.ddd so Outlook could not find them any longer.
I then opened Outlook 2007 and of course it gave me an error about not being able to find the .pst file and it suggested a new .pst file, etc. I accepted the new file.
Then, I went back to the original .pst file and renamed it back to what it was normally, I believe was outlook.pst
I then opened Outlook (which opened the new file, not any of the old files) and used the File>Import, to selectively import all of the items, except the calendar.
Unfortunately, this made the process a little long but I was able to finish it in about 30 minutes.
How-To
In Outlook 2007, Choose File>Import & Export. Choose "Import from another program or file." Click Next. When you get to the “Import a File” dialog box, choose “Personal Folder Files (.pst)”. Click Next.
Then Browse to the location of your .pst file. If it is in its default location it will be C:\Documents and Settings\User Name\Local Settings\Application Data\Microsoft\Outlook.
Once you get to the Outlook structure, you will notice many folders, as part of your .pst file. DO NOT choose the first listing, which will import everything within your .pst file. Rather, go down the list and selectively import one item at a time, being careful to NOT import the Calendar.
Once you have completed this, you can begin re-building your calendar. A lengthy work-around but it is nice the sync is finally working.
One other key item I found here. Recurring appointments seem not to sync if they do not have an end date. FYI
Hope this helps!

Answer 1

Something I read another user did successfully was export the old PST data into CSV, and import it into the new PST. That saved the step of having to reenter everything.
