When using Google Calendar with Outlook 2010 you may get an error like:
“Task Internet Calendar Subscriptions’ reported error (0x0004002B) : ‘Outlook cannot parse the property “CREATED”, near line x. The property is being ignored.
Here’s my solution,
1: export your google calendar
2: make a backup of the export (just in case you mess up something)
3: edit the .ics file in notepad or notpad++ or vi
4: look for a line starting with ‘CREATED:0’ and should end in some numbers
5: replace that line with something like ‘CREATED:20101231T183000Z’
6: do this for all the entries you find in the .ics file
7: save the file
8: import this file back in to google calendar
I believe this problem is caused by using google calendar on the iphone without using it in Exchange mode.
