Error description
When attempting to restore a mailbox where the logged on user's mailbox alias is a substring of another mailbox alias, this will fail with ACN0151E and ACN5909E messages: ACN0151E Errors occurred while processing the request. Mailbox restore failed. ACN5909E The MAPI subsystem logon has failed. Please check that you have an active mailbox and sufficient privileges for this operation. For example if 2 mailbox aliases exist, where one is a sub string of the other: user/mailbox alias: tivoli <----- logged on recovery user user/mailbox alias: tivoli1 Note that the failure will occur whenever there is another mailbox alias and the recovery user's mailbox alias is a sub string, regardless whether it is the mailbox being restored or not. The trace will show the failure for the ConfigureMessageService() on the profile which fails with MAPI_E_AMBIGUOUS_RECIP. If TESTMAPI is performed by the user whose mailbox alias is a substring, this will also show the failure: C:\Program Files\Tivoli\TSM\TDPExchange>tdpmapi.exe testmapi /mailboxalias=tivoli /excserver=hubble tdpmapi TESTMAPI Testing MAPI [HUBBLE, tivoli].... Set Profile Error: MAPI_E_AMBIGUOUS_RECIP . affected versions: MS Exchange Server 2003 and 2007 DP Exchange 6.1 . Keywords: zz61 displayname display name string
