Message: Unable to generate the e-mail address. Address type ‘%1’ is not valid.

This Error event indicates that the System Attendant found the proxy address type was invalid and could not generate an e-mail address of this type. This error will occur one time for each object the System Attendant tries to process. This error typically occurs when an address type that is in the Address-Types container in the Microsoft Exchange container in the Active Directory directory service has been corrupted.

User Action

To resolve this error, follow one or more of these steps:

  • If the address type is for third-party software, contact the software vendor.

  • If the address type is for one of the standard address types, such as SMTP, X400, NOTES or GWISE, contact Microsoft Product Support Services. For information about how to contact support, visit Microsoft Help and Support.
