Error AD update Operation for Proxy Address

[cdavis2]

I am getting the following error during an AD account update. Error while Update operation for account-lkumar in AD - [LDAP: error code 20 - 00002083: AtrErr: DSID-03151F38, #1: 0: 00002083: DSID-03151F38, problem 1006 (ATT_OR_VALUE_EXISTS), data 0, Att 200d2 (proxyAddresses):len 92 ]

The update works sometime but fails sometime due to the above error. I know its the proxyaddress field but was seeing how should I modify this to avoid running into this issue during updates. I'm thinking a replace function would be necessary but need a little assistance doing it for multiple values.

"proxyAddresses": ["smtp:${user.firstname}.${user.lastname}@example.com",
"SMTP:${user.email}"]

The following worked:

"proxyAddresses": {"Replace":[
"smtp:${user.firstname}.${user.lastname}@example.com",
"SMTP:${user.email}"]
}
}
{"Replace":[
"SMTP:${user.email}",
"${user.email}",
"${user.email}"
]
}
}
