Exporting and Importing PST Files - ExhangeOnline

Copper Contributor



I have come across an issue with Exporting/Importing a PST, can successfully export a PST and import it to another mailbox on another tenant


It's where the mail appears in the mailbox I have an issue with


the 'old' mailbox appears in a folder (named as the old email address) with all the mail items in here. We are planning to migrate the email domain over too, but as this was just a test, we haven't don't anything with the email domain yet.


is there any way of stopping this?


thanks in advance for any advice

That's the expected behavior, the "root" folder will be named after the user. Most import methods/tools offer you a way to specify a different "root" or a subset of the folders. That said, PST export/import should be your last choice for migration, use the native tools or third-party apps, as they offer much better experience overall.

thanks for replay, i am aware of tools that can do this, was investigating this method as it was small number <50 mailboxes, maybe about 2GB-3GB max per mailbox. which i could do in an afternoon
