Cisco Unity Connection:Error importing User

My client complained that one user is having issue with his voicemail.When a call comes the phone just keeps on ringing and it does't go to voicemail.

I have checked his phone line and there was no voicemail profile assigned to line.So after that call started to go voicemail.

Add Voicemail Profile

Next user requested to reset voicemail PIN.So in CUC when I tried to import user it was giving me error below.

 Tuesday, March 12, 2019 3:10:25 PM EDT ERROR importing user (username) with

 extension = 4153 : A User with the specified extension already exists in the Partition.

This error comes up because of the same extension of user is assigned to some another user as an alternate extension.

To find out which user has been assigned user extension as alternate extension,we need to limit search to specific partition.Also we need to select to display both Primary and Alternate Extension in Selected Partition.

Limit Search to Partition

By this we get the user who has been assigned with alternate extension.In here you can remove that extension,Now we can import the user with given extension in CUC.
