Office 365 Import PST - Folder structure not retained

On the last import of hundreds of PST files, I have found out that the folder structure was not retained. Can anyone confirm whether the following is working as expected? If you specify /, items ...

Hi Adam,

thank you for this response as well! It makes perfect sense... would you be able to help me with the following question as well, please - it would be great if this is a solution to not use the PST import process...

Environment A
Exchange 2010 mailboxes

Environment B
Active Directory + Azure AD Connect Sync + Office 365 Tenant (users without mailboxes)

Is it safe if I use the Express Migration Scenario (minimal hybrid) from Exchange 2010 to Office 365 Tenant? I would not install or sync with Azure AD as users already exist in the cloud. Would that work? And O365 tenant would remain synced with Environment B.

Thanks,

Yes, that's the source I was getting the info - more specifically express migration?

  I would say cutover migration! Since your tenant is already sync with another AD etc..

    Indeed... but the cutover migration requirement is that users do NOT exist in O365 as the cutover will create them... isn't that the case?
    
    Why would you not use the express?
