Some of you may have already noticed this, but I wanted to put this out there in an attempt to document just about anything I come across that is known to us here at Microsoft.

 You may notice that if you bridgehead your mail on Notes and sit Exchange behind it that the message headers get stripped before it hits Exchange.

(Internet)-----(Domino/Notes)-----(Exchange)

 This is known and by design. The "Received" headers are not copied to PR_TRANSPORT_HEADERS during conversion. This means that the only headers Exchange users will see are Exchange headers.

The only work around? Use SMTP for mailflow.

If you are going to be migrating with the Exchange 2007 Transporter Suite for Lotus Notes, you want this document.

This document not only has screenshots of how everything should be configured, there is an excellent troubleshooting section in it that fixes the bulk of the issues weve seen to date.

When running Directory Synchronization under Exchange 2007 with the Transporter Suite for Lotus Notes, you may encounter the following error:

Event Type: Error
Event Source: ExchangeDominoConnector
Event Category: Domino Directory Synchronization
Event ID: 8322
Description:
Error 800706ba: The Active Directory synchronization agent could not be opened.

Event Type: Error
Event Source: ExchangeDominoConnector
Event Category: Domino Directory Synchronization
Event ID: 511
Description:
Error {GRC:1404}: The application failed while processing.

When attempting to Sync users from Notes to Exchange, we need to generate addresses for contacts/users so that we can create them in Active Directory.

RPC connectivity is required from the Transporter server to the Mailbox server running the Recipient Update Service.

Attempt to open the event logs of the Mailbox Server from the Transporter server. If this fails, there is a firewall in place (hardware or software) that is preventing us from generating those addresses.

When a Domino/Notes or Exchange user tries to view Free/Busy you may receive the
following error in the Domino Console:

 ----------------------------------------------------------

 (There are three known reasons that cause this error)

1. This typically means that Domino was able to connect to Exchange to view
   free/busy data, but for some reason the users free/busy information was not in the
   Free/Busy public folder.
   
   This happens more often than not if we havent logged into the users mailbox or
   the user has never used their calendar. Attempt to view this users Free/Busy data
   from another Outlook client. If it does not show up there, thats a good place to
   start troubleshooting.
   
   However if you can see the data in Outlook but not in the Notes client and are
   recieving the above error, check the Administrative Group that we are viewing with
   notes. By default Free/Busy does not replicate between Administrative Groups and
   you will need to configure replicas.
   
   Note: Configuring replicas of Free/Busy information dramatically increases the
   time before a meeting is set and Free/Busy is able to be viewed remotely due to
   multiple layers of replication
   
   
2. We connect to the public folder database via http://server/public . By default
   on Exchange 2007 CAS, /public is set to REQUIRE SSL. This needs to be removed to
   not require SSL. SSL can not be enabled on this virtual directory or we will fail.
   
   
3. When a Exchange user tries to view a Domino/Notes users Free/Busy:
   
   Error:
   ODSTree_HostToCanAppend> Creating schedule object for Address@Domain, error = 3EEh:
   schedule object doesn't exist
   
   Make sure the Exchange user exists in Busytime on Domino/Notes

So some of you may have ran into this already, its a new problem we have been made aware of.

 Symptoms: Free/Busy information is one hour ahead for any meetings on or after November 4th.

This problem is only seen when the following conditions are met:
-Exchange 2007 is used
-Outlook 2007 is used to view "legacy" Free/Busy data
*or*
-From Outlook 2007 we are viewing Free/Busy data of Lotus Notes users across the Transporter.

note: 
-Outlook Web Access 2007 will not exhibit this problem
-Outlook Web Access 2003 will exhibit this problem

 The problem here has nothing to do with the Transporter. This problem is when viewing "legacy" free/busy data from either Outlook 2007 or Outlook Web Access 2003 on/after the date of November 4th. The Transporter is effected due to it storing Free/Busy data in a public folder and going across the Availability Service to get to it.

The cases behind this problem are ongoing, I will post an update here when I hear about a resolution.
