Our organization uses Exchange 2010. We currently have 2 Exchange Mailbox servers and 2 CAS servers. We have a few users on Google Apps and those users can see free busy information for all Exchange users but Exchange users cannot see free busy
information for Google Apps users. I was told by Google that we need to replicate the \non_ipm_subtree\schedule+ free busy Public Folder between our 2 Exchange Mailbox servers. I have created a Public Folder on the 2nd Exchange server, called Public
Folder Database ex2 (not sure if I needed to do this), to replicate to but when I attempt to do it, I receive this error:
--------------------------------------------------------
Microsoft Exchange Error
--------------------------------------------------------
The following error(s) occurred while saving changes:

Set-PublicFolder
Failed
Error:
Modification of the '\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY' folder isn't allowed.

--------------------------------------------------------
OK
--------------------------------------------------------

When I run the Get-Public Folder command seen below, it looks like the PF is replicating but only to itself. How can I get it to replicate to the 2nd Exchange server? When I view the PFs on the 2nd Exchange server, I see \non_ipm_subtree\schedule+
free busy PF but it doesn't have the 2 subfolders as seen on the 1st Exchange server.

Exchange server #1:
[PS] C:\Windows\system32>Get-PublicFolder -server "buff-exch1" -Identity "\non_ipm_subtree\schedule+ free busy" -recurse
| fl identity, replicas

Identity : \NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY
Replicas : {}

Identity : \NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX:/o=Kanoodle Amherst/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)
Replicas : {Public Folder Database}

Identity : \NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX:/o=Kanoodle Amherst/ou=First Administrative Group
Replicas : {Public Folder Database}

Exchange server #2:

[PS] C:\Windows\system32>Get-PublicFolder -server "buff-exch2" -Identity "\non_ipm_subtree\schedule+ free busy" -recurse
| fl identity, replicas

Identity : \NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY
Replicas : {}

Can someone please help? Any assistance is greatly appreciated!

Hello,

You can try replicating the folder via EMC->Tools->Public Folder Management Console.

By the way, in Exchange 2010, users on Outlook 2007 and 2010 never retrieve the free/busy info via public folders, they use autodiscover and EWS.

Thanks,
Simon

Simon,
Thank you for your response. I have tried replicating the PF via EMC -> Tools -> Public Folder Management Console, the error from above is what I get when I try to replicate:
Microsoft Exchange Error
--------------------------------------------------------
The following error(s) occurred while saving changes:

Set-PublicFolder
Failed
Error:
Modification of the '\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY' folder isn't allowed.

The thing I do not understand is, Google Apps users are able to see the free/busy information of Exchange Users. When Exchange users try to see Google
Apps user's free/busy information, they cannot. Wouldn't this be an issue with something in Google Apps? When we convert a user to Google Apps, email address for the Google Apps is removed from Exchange. I then need to create a mail enabled
external contact pointing to an alias domain in Google Apps.
When I go into Exchange's OWA and try to add a calendar entry and view the free/busy information of the alias Google Apps domain user (the mail enabled external
contact), I receive this error: No Information (Error code: -2146233088)
When I go into Exchange's OWA and try to add a calendar entry and view the free/busy information of the primary Google Apps domain user (the one that was removed from Exchange),
I receive this error: No Information (Error code: -5009)

The big problem here is, the documentation provided by Google is for Exchange 2003 or Exchange 2007. Since PF's are not used in Exchange 2010, there has to be a different way of making this work. Here is the documentation if you are interested.

Hello,

I do agree with you that the issue should be related the Google Apps since the Google users can see the F/B info in your org.

Thanks,

Simon,
Turns out it wasn't on the Google Apps side. Since I couldn't replicate the PF Schedule+ Free Busy to our other mailbox server, I shut down the 2nd mailbox server. After restarting IIS on both CAS boxes, viewing free busy information from the
Administrator account (Exchange) to a Google Apps user worked. When I tried to view that information from my Exchange account, it would not work. After adding the ExchangeLegacyInterop permission to my AD account, once it replicated through the
servers, I was able to view the free busy information of all the Google Apps users.
Thank you for your time and assistance.
