Hi,
we are transitioning from Ex2003 to Ex2010. Now we are in a phase of coexistence.
In general there are no problems when sending emails from 2010 to 2003 and viceversa.
The flow is regular in all relations 2003-2010, 2003-Internet, 2010-Internet.
Nevertheless in some circumstances an NDR is generated.
Initially we noted that, randomly, when a moved user sends an email with another email attached(in this case only!) to a non moved user, the email is not delivered. A deeper analysis made me realize that the phenomenon is not random. Exchange 2003 had two data stores, say A and B. The NDR takes place only when an email is sent to datastore A, while with datastore B there are no problems at all. Apparently there is no difference between the two datastores. Verified the properties and security of the two datastores but they are just the same.
I don't know what other check I can do.
Is there anyone able to give me a hint about a possible solution?
I cannot think of moving the mailboxes from datastore A to datastore B on the W2003 side and the customer is unhappy.
Thank you in advance
