iPhone 4.1 with Exchange 2003

Posted on 2010-09-09
Last Modified: 2012-05-10
One of my customers installed iPhone IOS 4.1 (released yesterday) and that broke the calendar.

Contacts OTA sync works.
Calendar OTA sync doesnt.

When this person tried to sync calendar from iTunes and clicked the “sync calendar” box, this creates a 2nd version of the calendar on iphone called “From My PC.”  

OTA mails work
OTA contacts work.
OTA calendar doesnt ?

any clues ?

Check for large attachments in the Calendar (View by categories, and add the size field with field chooser...)
Is Your AD Toolbox Looking More Like a Toybox?

Cheers sunnyc7, there is the solution.

When configuring the exchange account on iphone, it asks if the synced calendar will erase the existing one or not.
When you just finished configuring the exchange account on iphone, mail is ON, contacts is ON and the calendar is turned OFF by default.

If you turn it ON, it will ask if you want to erase or not the existing calendar.

This will probably be the last step. The user has loads of GPS enabled apps.
will have to try a backup and restore.

I expect you walked near the server and it got the message!  I often fix problems like that too : )
