IC74465: DATA PROTECTION FOR EXCHANGE INDIVIDUAL MAILBOX RESTORE PERFORMS SLOWLY IN A GEOGRAPHICALLY DISTRIBUTED AD MULTI DOMAIN FOREST

APAR status

• Closed as program error.

Error description

• In a geographically distributed Active Directory (AD) multi
  domain forest, Data Protection for Exchange Individual Mailbox
  Restore might spend a great portion of its processing time in AD
  queries to each MS-Exchange server in each domain. Especially
  those servers without mailbox (without objectClass=user) cause
  much delay.
  These queries may take hours and can be mistaken as a hang.
