Hello,

We started to notice that when we move a user from our legacy exchange 2007 to exchange 2013, the contact list appears twice for users.  I heard CU6 was suppose to fix this issue but we went ahead and downloaded the latest version and we are still seeing this.  Can anyone provide guidance on how to stop this for the remaining migrations?

Thanks

Hi,

I'm pending research.

 

Thanks

Thanks for the reply.  Please let me know if you find a solution.

Hi Joey,

I'm back : )

According to your description, I know that the contact list appears twice for users after moving users from Exchange 2007 to Exchange 2013.

I notice that you want to install CU6 to fix this issue, based on my knowledge, CU6 can cause an known issue when you are using Exchange 2007 and 2013 coexistence and query mailbox move request via EMS. However is known issue has fixed in CU7, I suggest install CU7 for testing.

 

Thanks

Hi Joey,

Sorry for my late reply.

I notice that you have install the CU7, how about migrating a test mailbox to Exchange 2013 CU7?

I suggest try to use MFCMAPI Tool to delete the duplicated contacts.

 

Thanks
