Auto accept meeting requests from external users for Room mailbox
Hi Everybody,
I've got two separate AD domains/ exchange organisations (Exchange 2007, with Outlook 2007) whose users both share the same boardroom.
Can anybody suggest a solution that will enable users in both domains to share the same calendar or resource mailbox?
I've tried everything. The closest I've come is to set up a resource mailbox on one domain and enable automatic meeting acceptance, but this only works for users authenticated in the same domain as the resource mailbox. If users from the other domain send
a meeting request, that appointment is not automatically accepted, and I can't find any way of changing this behaviour.
I am totally grateful for any help with this problem.
Cheers,
Jude

Hi,
Cross forest calendar sharing is a new feature in exchange 2010, federated sharing required at-least one exchange 2010 CAS server, have a look into these articles :
http://technet.microsoft.com/en-us/library/dd638083.aspx
http://technet.microsoft.com/en-us/library/bb125182.aspx
Exchange 2010 will allow users cross forest to share free/busy info, calendars and contacts via the new federations features in this version. You can also use the
these federation features if you have two Exchange 2007 SP2 orgs in which at least one Exchange 2010 Client Access Server has been deployed.Ripu Daman Mina | MCSE 2003 & MCSA Messaging

Hi Jude,
This behaviour is by design. When Resource Mailbox accepting the meeting request from the organizer, Exchange 2007 will match the user in the GAL, it will not process the meeting request and moves it to deleted items without sending response since the
user is external user.
To workaround this issue, please perform the following steps:
1, Set-MailboxCalendarSettings <resource mailbox name> -processexternalmeetingmessages $true
2, Create the contact for the organizer in the Exchange server.
If all the users need to book Resource Mailbox, you should use MIIS 2003 to synchronize the global address lists.
Thanks

Hi Ripu,
The federated sharing capabilities of 2010 Exchange look great, but unfortunately I'm stuck using Exchange 2007 due to cost constraints. Thanks for your reply.

Hi Allen,
This is a great workaround. Many thanks for the reply; it's very helpful. Another question for you, do you know if it's possible to publish the calendar of the resource mailbox online somehow? WebDav, or Office Live?
Cheers,
Jude

I have the same issue. I've set the processexternalmeetinmessage to true and I have addressbook synchronization between the environments. Still are the request placed as tentative in the room's calendar and I don't get any response back.
Is there something more that has to be done?
Thanks
Peter

We're having the same problem. We use inter org replication w/ another company and that company cannot book rooms even though we enabled processexternalmeetings. I can see the meeting request is immediately moved to deleted items folder.
Any suggestions?
Thanks,
Coco

Having the same issue here. I can see the meeting request in the deleted items folder, but the request is not accepted. Are there any workarounds not including creating a contact?
