Microsoft
Exchange Server 2007 Service Pack 1 (SP1) lets you create multiple users who
have the same
mailNickname attribute by using the
New-Mailbox command in Exchange Management Shell. However, when you try to
create more than 1000 users who have the same
mailNickname attribute, you receive the following error message:
A proxy generator DLL on server <server name> could not be found or failed to initialize. Proxy addresses for the current recipient cannot be calculated. Please ensure that all the proxy addressgenerator DLLs have been installed on the target server.
