Hi

We have exported mailboxes from a 2010 Exchange server to .PST files. Then moved the files to a new Exchange 2013 server in a new domain. 

When we import the .PST files with powershell the modified/created dates on the mailbox items are set to the point it was imported to the mailbox. (The attribute time stamp)

Is it possible to run any command wich will keep the original created/modified date on the items?

Hi,

According to your description, I know that you want to keep the original created/modified data on the items which import from .pst.

If you are considering about the retention policy, don't worry about it. The retention age is calculated based on delivery date or date of creation and message-received date. More details to see following article:
