Yet Another Exchange won't sync Calendar

Question

This is not a question but an answer, most appropriate to add to thread 7713558 but that is closed.
I had my Outlook email, calendar and contacts sync'd and of course made the mistake to also sync it with itunes getting double entries. Removing the contacts and calendar on the iTouch however would leave all birthday events still in the calendar. Since it is easier for me to work on Unix than on iTunes I jailbroke the Touch and following an available instruction SSH'd in and copied /private/var/mobile/Library/Calendar/Calendar.sqlitedb to my PC and edited it with sql to remove the birthdays and placed the calendar back on the iTouch. Now since then it wouldnt sync my calendar. Still would have the contacts and the email. However when trying to fix it, I removed the account and recreated it, rebooted the iTouch - no email no contacts no calendar.
Then I SSH'd back into the Touch and copied the old calendar file in - be it with another name. I then tried to delete the existing calendar.sqlitedb which it wouldnt let me do and then I renamed it. To my big surprise I suddenly saw 3 calendars: the renamed, the backup from the PC and a brand new calendar.sqlitedb with a lot more bytes!! Suddenly als email came in and contacts were there.
I must admit that in the meantime I also switched local syncing off and on with itunes but that only resulted in outlook sync crashes. When I reconnected the iTouch to itunes I immediately stopped the syncing and unchecked the local contacts, calendar and email. I rebooted the Touch. It is all a bit messy in terms of procedure but I dont want to take away the reality of problem finding and dont know exactly what the right procedure is. But I think renaming the calendar was the trick that did it.
One more thing about Exchange syncing. Even when having all the username domain etc fields inputted right then in my case it was still necessary to send an email to my Exchange admin to request enabling mobile access!! You can imagine how many times I tried different settings! D**n it!
I like the iTouch because it is such a lovely Unix computer but it hasnt been one bit easier learning to squeeze this device into my day to day needs than exploring Ubuntu for the first time.

Reset sync history. On a mac open isync then choose preferences and reset sync history. Be sure to back up your iPhone also before this happens. Are you sure that you don't have manually manage music and video checked underneath the options page when you first open iTunes? This could also possibly hinder your ability to sync over music.
