We trust each other don't we part II: Can I share Free/Busy information between two Exchange 2007 organizations?

re: We trust each other don't we part II: Can I share Free/Busy information between two Exchange 2007 organizations?

We have an Exchange (2007) resource forest with a ONE-WAY trust to our account forest/domain that does not have Exchange (i.e. no schema extensions). Free/Busy information does not seem to be available for users who are logging in with our account domain credentials. As an individual, I can set 'anonymous' permissions on my calendar to Free/Busy and that works but I can't seem to do the same for resources such as meeting rooms that people would like to have access to when booking events.

Any ideas?

Thanks,

Trevor

Jorge,

Good question. These cmdlets would only apply in a scenario where you have Outlook 2007 clients connecting to Exchange 2007 server and you want to view free/busy on another Exchange org.

If you have Outlook 2003 across the board in both orgs, Outlook would not know how to use autodiscover/web services (in diagram listed above) therefore you would not need the cmdlet until you switch to Outlook 2007.

Thank You so much markga for your quick answer..! One more question please...

Right now I have InterOrg Replication Tool in production and it is working pretty well for getting free/busy information from users from both forests. (Ex2007 <> Ex2003)

Outloook 2003 is the standard email client for everyone.

Running this this cmdlet could affect or change the way free/busy information is being checked nowadays?

Thank U in advance,

Jorge

Jorge,

You have to use the SMTP domain vs. the actual Forestname for the Forestname parameter. That is the confusing part of the command.

Here is a referenece:

The ForestName parameter specifies the SMTP domain name of the target forest for users whose free/busy data must be retrieved. If your users are distributed among multiple SMTP domains in the target forest, run the Add-AvailabilityAddressSpace cmdlet once for each SMTP domain

Hi,

Im having some doubts so I hope someone out there can help me.

The scenario I have is the following:

Forest 1: Forest1.com, Ex2003

Forest 2: Forest2.corp, Ex2007

I Have smtp sharing configured beetween both of them.

On Forest2 Exchange server I have:

Configuration for forest miDominio.com was not found in Active Directory. Run the Add-AvailabilityAddressSpace command in the Exchange Management Shell for an Exchange Server 2003 Active Directory forest

So The question is... Why the error points to Forest "miDominio.com" and not the actual name of Forest1???

miDominio.com is my Email Public Domain but there is no Active Directory Forest with that name... What should I do?

RSDTech,

Give me a bit more info about the interop scenario. Ex2007 to Ex2007 with Outlook 2007 on both sides or different? Cross org free/busy in OWA works both ways? If yes, Outlook 2007 should leverage the same web service assuming autodiscover is working properly, etc.

I've done this and can only see the Free/Busy info with OWA, with Outlook 2007, the information is unavailable. To fix this, I added Send-As permissions to NT AUTHORITY/SELF and if I am a local contact to a user in the other company, they can see my Free/Busy with Outlook. If I am just a contact in their GAL, they cannot.

Am I missing something?

Marc,

Yes, this will work. For 2007 Forest to 2003 Forest scenario you will need to:

1) Setup Interorg PF replication

2) Replicate Schedule+ Free/Busy pf both ways

3) Use this command on the Exchange 2007 server side:

Add-AvailabilityAddressSpace -ForestName:school.edu -AccessMethod:PublicFolder

Exchange 2003 users will access Exchange 2007 users Free/busy via Interorg PF replication.
