Hi All

(Posted to Hosted Email as well).

We are completing a a Co-existence deployment of HMC 3.5 to 4 upgrade; all has gone quite well - until the Importing of OAL's per the Migration whitepaper.

Procedure 3.26: To Move a Business Organization’s Offline Address Book into Hosted Messaging and Collaboration version 4.0 Provisioning.

We are at a total loss: 

1. We Can see the OALs in the Exchange 2003 EMC as still being on the old Exchange 2003 server.
   You can also see them on the Exchange 2007 server as still being on the legacy backend.
2. The OALs are not migrating to the new Exchange 2007 Server - using the Migration ImportOfflineAddressBook.xml (Rather the catastprohic error - see below)
3. We'ere running Exchange 2007 SP1, and have installed the HMC 4 rollup 2.

Provtest ImportOfflineAddressBook.xml /x2

Result:

C:\xml2>provtest /x2 ImportOfflineAddressBook.xml
<response>
  <errorContext description="Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))
Cmdlet='Update-OfflineAddressBook'

From EVENTVIEWER on MPS01:

Two possible reasons for the failure are that the System Attendant Service is not running or you do not have permission to perform this operation.

We have confirmed that hte System attendant is running on the Mailbox server and (I believe) the permissions look okay:

• MPFServiceAcct is a member of MPSExchangeAccts
• MPSExchangeAccts is a of Exchange Organization Administrators
• MPSOabRebuildAcct is a member of MPSExchangeAccts
• There are two MPSPrivAcct-xxxxx (where xxxxx are numbers) both these accounts are members of MPSExchangeAccts
• MPSServiceAcct also has Delegation rights “Trust this user for delegation to any service (Kerberos only)”  

Any idea would be wonderful.

Thanks.

Peter.
