Event Id2027
DescriptionUnable to generate the e-mail address. Unable to load address module DLL name for address type address type. Error error code.
Event InformationAccording to Microsoft:

This event indicates that the System Attendant was unable to generate an email address that was defined in the Recipient Policy because the mentioned third-party DLL file was not accessible.
1. This issue can occur because of an invalid or third-party e-mail address generator. When the System Attendant starts, it attempts to load an address generation dynamic-link library (DLL) file for each address type that the Recipient Update Service is responsible for stamping. If the System Attendant is unable to load the DLL for any address type, the Recipient Update Service fails to stamp any e-mail addresses and the 2027 event is logged.
2. This issue can also occur if the third party DLL file is present but the SYSTEM Account does not have full control rights to it.
User Action :
1. Create the folder structure mentioned in the 2027 event and place the third party DLL file in that directory. Update the Recipient Update Service.
2. Give the SYSTEM Account Full Control rights to the EXCHSRVR directory and all sub-directories.
