iPhone losing contact information

I have an iPhone 4 have my mail, contacts and calendar linked via microsoft exchange (through office 365). Over the past 6 months I have been having regular issues whereby somehow either my phone or the exchange server is deleting contact information (phone numbers, email, address, etc) completely and leaving only the contacts name in my phone. Add to this sometimes it then duplicates those contacts and both have no information other than the name and it never happens to all my contacts rather anywhere from 1 to 50-60.

I assume it is my phone as no other employee has this issue with their iPhones (I have the same setup iPhone with exchange company-wide) but I have exhausted all possible solutions to solve this so I am hoping this issue has been come across before and can be rectified.

Kind regards,

Troy

Do you have multiple email accounts created on the Iphone ?
Is it upgraded to the recent updates ?
How often does it happens ?
Is the issue with all users .... any Android\Win7 phone ?

If the issue has not been reported by anyone else apart from you then yes most possibly it is your mobile that is the problem child but assumptions would not solve our problem.

firstly check if there has been any upgrade done to your mobile post which this issue poped-up. Maybe any upgrade that took place on your device.
Why not checking with your vendor if your mobile has any issues as such. Infact in some cases they help with re-configuring your profile on their test phones as well to test if all is well with the phone or not.

Also let us know if things sow up properly in OWA as you stated that your phone or exchange is deleting contacts. So checking things with OWA is a must.

OK, will address the questions in list form:
 - only email account on iphone is exchange
 - phone updated to 5.1.1 which is current
 - happens irregularly, once a month to couple of times a week
 - we dont have any win 7/andriod phones (have 16 iphones and this is the only problem phone)
 - have logged issue with apple but they claim not to have heard of it
 - owa, iphone and outlook all show contact information gone and only the name showing

- have logged issue with apple but they claim not to have heard of it - that is the most common reply from vendor :)

What if a user does not work with Iphone for a couple of weeks to check if any changes happen.

My gut feeling says something with Iphone.

Just a thought. Have we tried using another Iphone Set to confirm all is well with the device?

reload the iphone to the latest ios version and try again.
