Hi,

there are two organisations. In one organisation there is a mailbox with the email address: "address@domain.com" and I want to modify the mailbox plan. When I try I get the error:

System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: Error executing 'SET_MAILBOXPLAN_RETENTIONPOLICY_ARCHIVING' task on 'address@domain.com' EXCHANGE ---> System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Management.Automation.RemoteException: This operation requires a unique source object, but multiple objects have been found. Please remove any wildcard characters and check the data source for corruption. 

I checked and found out that there is a contact with the same email address in another organisation (acme.com). It is there because they want to include this email in a distribution group in that organisation (acme.com).

Is there a way to overcome this issue?

Thanks
