Hi,
I am configuring cross forest co-existence between two Exchange Orgs and I would like to clarify the purpose of a particular setting in Exchange.
The environment I would like to allow OrgWide Free Busy with my Exchange org is un-trusted from a domain perspective. What I would like to understand is the setting Set-AvailabilityConfig -OrgWideAccount <AccountName>
When I add this account to my Exchange Org, will this allow the other exchange or to see my users availability data (after they have configured a new Availability Address Space (using the -Credential parameter)?
Could populating this value on my Exchange Org have any impact on other organizations that already have availability sharing setup with my Exchange Org (note the property is currently $Null on our Exchange, therefore I am assuming other organizations are referencing availability using the trusted forest method whereby Exchange servers are given a permission within the environment (cmdlet below))?
Get-MailboxServer | Add-ADPermission -Accessrights Extendedright -Extendedrights "ms-Exch-EPI-Token-Serialization" -User "<Remote Forest Domain>\Exchange servers"
Thanks,
Mike.
