Since we updated to SP2 Rollup 4 from RTM, we're now receiving this error on our Edge Server
Reading recipient with routing address bob@domain.com from the Active Directory failed with data validation error. The detail of the error is Microsoft.Exchange.Data.Directory.Recipient.NonUniqueProxyAddressError
I've already seen this post: http://social.technet.microsoft.com/Forums/en-US/exchangesvrsecuremessaginglegacy/thread/7018962c-d39b-49e9-b765-ce8264be3945 it did not help unfortunately.
Over the past 24 hours, I have over 6,000 events with this same error, many of them are unique, there are hundreds of addresses reporting this error.
In AD if I run a custom query for proxyaddresses=smtp:bob@domain.com only one entry comes up.
I've also run this and it only returns one entry.
Get-Recipient -ResultSize unlimited | where { $_.EmailAddresses -like "*bob@domain.com*" } | select-object DisplayName, EmailAddresses | fl
Does anyone know how to fix this please?
