Here is the scenario.....

I am in company A, and I have a business unit that is a separate company for legal reasons  lets call them Company B.  they have their own Exchange 2003 organization.  these users also have exchange mailboxes in my Exchange 2013 org, Company A.  they also receive email in Company A, and we have set up a forwarding rule on the mailboxes that forward the email to the user, but also keeps a copy of the email in the company A mailbox  now, we have decided to completely move these users from Company B into company A, and sever all ties to Company B.  We know that there will be duplicates because of the way that we are forwarding, but Exchange by default will not import the duplicates.  here is what we are doing

• -exmerge mail from company B mailbox to PST
• -add X.500 to migrating user
• -import pst into user's mailbox

Using this process, I have to report on statistics including items that transferred, and items that did not transfer and the reason.  this is where the challenge has been.

I am unable to determine exactly what, and why items were transferred, or not transferred.  for example...  here is a piece of the Get-MailboximportRequestStatistics  report.

EstimatedTransferItemCount             : 1409

BytesTransferred                       : 24 KB (24,579 bytes)

BytesTransferredPerMinute              :

ItemsTransferred                       : 0

as you see....  the estimated transfer item count is definitely different than the transferred items.  I assumed that this was because of duplicates, but I cannot prove my theory.  I looked in the detaied logging, and see where items are skipped, but that number does not equal the delta between the estimated transfer item count and items transferred.

I have looked high and low, and cannot figure this out....  any help would be appreciated.

So as long as there were no errors your assumption would be correct, however that said since your using ExMerge there is a 2GB limit for PST's and as luck would have it ExMerge doesnt stop if it goes over it just corrupts and your done.  So how big are the PST's

Hi,

In the result of Get-MailboxImportRequestStatistics cmdlet, there is a parameter called FailureType. This value specifies the failure type. We can refer to this value to check the Failure Type of Mailbox Import Request.

And if you specified the IncludeReport parameter when using the Get-MailboxImportRequest cmdlet, the report value specifies information that can be used to troubleshoot the request.

Best Regards.
