    Hi all,

             Performing an interforest migration from 2003 to 2010 - so decided to go the pst route for mail migration.

    Exporting was fine (took a while... but they have a lot of data) but importing into 2010 is painfully slow.

    Exchange server is 2010 SP2 RU1, client importing the PST's is outlook 2010 SP1 with EMC 2010 SP2, both server amd client are doing basically nothing CPU, disk and network wise....
    i have modified the MSExchangeMailboxReplication.exe.config to allow 8 simultaneous migrations and restarted.

    im using get-mailboximportrequeststatistics -requestQueue Database1 | where {$_.status -eq "InProgress"} | sort-object percentcomplete -descending to have a look at the status... and basically i might get 1% movement every 5 minutes on one of the PST's.

    The PST's range from 10mb to 2GB....

    I have other articles around on this, but they all seem to indicate its been fixed since SP1 RU3.... which it hasnt for me!

    Suggestions on what to check ?

    Hi ,

    I recommend you install the update for your Exchange.

    The Exchange Mailbox Replication service crashes when you use the "New-MailboxImportRequest" command to import a PST file to an Exchange Server 2010 mailbox:

    yep - so as i said, the exchange server is 2010 SP2 RU1..... so i cant apply that update, as it is older. (im making the bold assumption that SP2 will contain all of the fixes from SP1 RU2)

    Hi ,

    Sorry, I don’t notice the version.

    Please try to do the following steps and narrow down the issue.

    Please try to run new-mailboximportrequest with -verbose to get more information.

    Besides, do you try to import single maibox pst file ?

    Also you may try to restart Exchange Transport service and Mailbox Replication service, then check the issue again.

    Hey Wendy,

                        yep, restarted services etc - no luck.

    Ended up being two things

    1) The exchange server is running on VMWare as was resource limited (seems to be a common, i dont get it)

    2) Importing from a network drive was about 20% the speed of copying the psts locally and then importing them from there.... might be handy if the doco mentioned this kind of thing
