One of the mailboxes fails but it seems in the log that all messages are copied but some errors confuses me. Does anyone know what these errors says?

Not all that uncommon, for systems that have been in use for a while. These messages are corrupt, and not totally readable. In most cases, this sort of corruption occurs on attachments, or embedded graphics objects. Usually, the user is unaware, however there will be some old messages with missing pictures, or attachments that cannot be accessed. If you hunt for them, you can find them.

Not sure of a great way to do that. You can compare item counts to determine which folders have skipped items, then start narrowing it down by alphabetical or date counts. Usually, the "before" mailbox will have some items that cannot be opened, they will be missing after that move.  Nothing get "lost", it just goes from there but unacessible, to not there at all.  In nearly all cases I have seen, the missing items are inconsequential, and the users don't notice thay are gone. Calendar entries seem to be a commom one.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Hi,

These corruptions are common while moving mailboxes from one DB to other, normally those corrupted items are mostly generated by clients than server. The reasons may vary time to time, sometimes older calendar entries , sometimes corrupted rules, sometimes when two or multiple clients trying to access same item (mostly activesync and outlook client).
its not bad to mention "BadItemCount" while moving databases. 10 - 20 is a good number. but still you want to eliminate more corrupted items then you need to use "AcceptLargeDataLoss" parameter.
New-MoveRequest -Identity "user@domain.com" - TargetDatabase "Target_db" -BadItemcount "15"

Thanks

in line two of my screendump it says "Copying messages is complete" so I suppose all emails are sucessfully migrated. But all the errors goes for folders or am I reading it wrong?

see Mailbox Replication service (MRS) is responsible for moving contents from mailbox, it wont transfer corrupted content. Thats why its good to mention 'Baditemcount' while moving mailboxes. if you dint mention parameter 'BadItemCount' it will take "BadItemCount = 0". so  your mailbox movement will get interrupted once it find a corrupted item.

thanks
