Ämne: TDP Exchange indiviual mailbox restore failure

Hi all,

during the installation of the TDP for Exchange product for a new
environment we ran into the problem that the restore of an individual
mailbox to a .pst file didn't work, the trace showed the error
'MAPI_E_NETWORK_ERROR'. TSM support suggested that it is the problem
noted in http://www-01.ibm.com/support/docview.wss?uid=swg21445283 .

However, the 'workaround' described in this technote can't be applied in
our environment (the Mailbox Server and CAS roles are on different
servers for a reason, and between these servers is a firewall preventing
Outlook clients from talking directly to the mailbox server). Has anyone
seen the same problem, and if yes, how did you deal with it?

OS: Windows 2008 Server R2, 64bit
B/A-Client: 6.2.1.3
TDP Exchange: 6.1.2.1
TSM Server: 5.5.4.0 on AIX

Regards,
