Installing Version 7 on Multiple Domains
Hello - we are trying to install SourceOne v.7 with one instance, onto 2 domains with a 2 way transitive forest trust. We have 2 different domains and forests under one company. We have a "shared" network where the network can freely see either domain, but we have the SourceOne servers joined to "Domain A", which it can see just fine, but SourceOne cannot even see the other Exchange Servers (all are 2010 SP2 in both domains) through the software (can ping and see via IP or hostname). Any suggestions or starting points?

Hello webb72475,
SourceOne supports two options when working with Exchange and Active Directory environments. Only the Exchange Resource Forest configuration is supported for multiple Active Directory forests. I have included a section from our Admin Guide page 36:
(Sorry for the poor formatting, the table looks much better in the documentation)
Table 3 Active Directory forest configurations
Active Directory forest configuration
Single Forest
A single Active Directory forest containing one or more
domains. Each domain contains one or more Exchange
servers. A common global address list (GAL) is used for
all domains.
This is the simplest topology and is recommended by
Microsoft in the document Active Directory Forest
Topologies which is available online at:
http://technet.microsoft.com/en-us/library/bb124765(EXC
HG.80).aspx.
EMC SourceOne configuration
Single or multiple domains in a single forest are
supported by EMC SourceOne as described in
the EMC SourceOne Email Management
Installation Guide.
Multiple Forests (Exchange Resource Forest)
Multiple Active Directory forests are used. One forest is
dedicated to running Exchange and hosting Exchange
mailboxes. The user accounts associated with the
mailboxes are contained in one or more other separate
forests.
This configuration is also referred to as a Dedicated
Exchange Forest configuration.
EMC SourceOne configuration
Only EMC SourceOne Offline Access should be
installed in the forests not containing the
Exchange server.
All EMC SourceOne components must be
installed in the same Active Directory forest as
the Exchange server. Refer to the EMC
SourceOne Email Management Installation
Guide for information on installing these
components.
“Configuring Exchange PST processing across
Active Directory forests” on page 37 describes
the additional tasks you need to perform if you
are processing PST files across multiple forests.
Multiple Forests (Exchange Cross-Forest)
Multiple Active Directory forests are used. Each forest
contains an Exchange server and the user accounts for
users of that Exchange server.
This configuration has several disadvantages and
requires extensive synchronization of active directory
objects across forests and requires replication of other
data.
EMC SourceOne configuration
Not supported by EMC SourceOne.
Only the Exchange Resource Forest
configuration is supported for multiple Active
Directory forests.
Hope this helps!
Thanks,
Brad
