IMAP to Exchange 2007 migration   

Upon migrating a mailbox from IMAP to Exchange 2007 I get the following error 
message:

An item has failed property validation and will be ignored.

Does anyone know what this means and what I can do to get past it?

Thanks!

I'm sorry, I didn't mention that.  I'm using the Transporter Suite for IMAP.  
And the error message occurs for certain emails.  I can't find any 
commonality with the emails, but the migration then fails.  Any thoughts?

Masha - Just curious. What is your IMAP server and what kis of
throughput are you getting while migrating mail data. I am planning on
doing one for a big setup and since this is a new feature added to the
Transporter, there is very little or no information available at this
time.

Thanks

Hi Marsha,

Have you found any solution to that problem? I'm experiencing the same 
problem. The only difference is that my script was working properly 2 days 
ago, but no more now and I haven't changed anything in it! So I think it's 
something that has been changed somewhere in my organisation, but don't know 
where to search!

RE: IMAP to Exchange 2007 migration   

Hi everyone,

I got rid of this message by adding TargetServer to the .csv file as one of 
the possible fields (such as SourceLoginID, etc) and then specifiying one of 
my client access servers under the field.  My error specified that the value 
could not be null and the property that it thought was null was 
'targetserver'.  Try and see if it helps for you.  

For the record, this tool really can be very inconvenient.  We have actually 
abandoned it because unless you specify each user's password in the .csv 
file, this tool will not work.  What happens is that the admin credentials we 
use traverse each mailbox and can't handle separate sessions.  There is no 
'stop' command so to speak to delineate where one mailbox ends and another 
begins.  The result...all mailboxes that are migrated at the same time get 
all mail in every other mailbox!!!  Obviously, not an option.  Microsoft at 
this time cannot support the one (admin account) to many (multiple mailboxes) 
scenario.  This is the official word I got from the Transporter Suite team.  

We also are unable to 'push' from the IMAP server since each message that 
passes through the SMTP interface is stamped with the current date.  The 
result....the internal date is not preserved and every message in your 
mailbox shows a received date of today.  Not an option for us and I suspect 
not for many other people.

If you can obtain passwords for all your users or reset their passwords to 
something you know, this tool will work perfectly, unfortunately, that is 
absolutely not an option for us.  We have switched to client side tool.

Good luck everyone!!
