Problem:
In a migration environment with exchange 2007 and exchange 2010 we have client (outlook 2007) that hangs 10 seconds when sending a meeting that books a resource mailbox residing on Exchange 2010 mailbox server.

Microsoft say:
In a support case to microsoft they acknowledge this problem as a feature in exchange 2010 when booking resourcemailboxes. They state that this is a fix (code release) for office 365 (clod exchange) where microsoft is not using public folders. This fix is for Outlook 2003 clients when connection to the clod. Outlook 2003 use public folder for accessing free/busy information and when microsoft closed this door in office 365 they had to get a workaround for outlook 2003 users. This fix is intercepting outlook 2003 calls to public folder on a mailbox server and redirecting them to webservices (EWS) on a CAS on behalf off mailuser.

Outlook 2010 is not affected like outlook 2007.

This is not a correct picture yet. A better one is coming soon.
1. Client try to get free/busy information from it’s mailboxserver holding public folder
2. Mailbox server trying to access https://webmail.org.se/EWS/Exchange.aspx for free/busy information behalf off mailuser insted of accessing public folder.
4. CAS answering mailboxservers request for information.

So this is a fix for exchange in clod only!? – Yes and No…
It is a fix release for both clod and on premise. So it is affection or local environment to and that is bad!

We noticed the following event id’s being generated on the Mailbox server MBX.org.se
Time:     2011-04-01 10:39:52
ID:       4002
Level:    Error
Source: MSExchange Availability
Machine:  MBX.org.se
Message:  Process 2796: ProxyWebRequest CrossSite from S-1-1-0 to https://webmail.org.se/EWS/Exchange.asmx failed. Caller SIDs: NetworkCredentials. The exception returned is Microsoft.Exchange.InfoWorker.Common.Availability.ProxyWebRequestProcessingException: System.Net.WebException: Unable to connect to the remote server —> System.Net.Sockets.SocketException:
No connection could be made because the target machine actively refused it 100.101.102.103:443

Why do we have a problem?
Our Exchange 2010 mailbox servers could not connect to https://webmail.org.se/EWS/Exchange.asmx
Well, we can not access Internal URL for EWS from our mailboxservers.
Is this correct? No!
But our network design is not letting us do this right now.
When we worked around this problem we no longer have a problem with outlook 2007. So thats good!
But this proxy fix for outlook 2003 in the clod is still affecting outlook 2007 even thou we no longer see a problem.
