Hello Team,
Our External client provided .pst file in our azure storage for exchange 2010 Mailboxes and one of my team member Copied over contents of PST to a newly created folder in user's mailbox called 'Exchange 2010 Emails;.
Copy .Pst contains to new folder - Is this Migration or not? Can we add domain to O365 from Exchange 2010 after copy mailbox content to o365 user'mailbox?
Please note: External client cannot provide us any permission to exchange server due to client policy(Not possible for staged/cutover/hybrid).
I am writing here to confirm with you any update about this thread now.
If the suggestion below helps, please feel free to accept it as an answer to help more people.
Hello Microsoft,
External client providing .pst file for public folder as well but microsoft doesn't support .pst file for public folder migration.
In this case - we will loose public folder if we add domain to O365 from Exchange 2010.

About public folder, you could open this PST with Outlook, then drag content from PST file to Exchange online public folder directly.

Apologies,
s I have discussed with team and found that there is EDB file not pst file.
do we loose emails if we add domain to o365 from exchange in this case?
If so, you will cannot export EDB file to Exchange online.
Yes, migrate mailbox in the way of PST is also a common migration mode. Use network upload to import your organization's PST files to Microsoft 365
About adding domain to Office 365, you could have a look about this article: Add a domain to Microsoft 365
After adding domain name and changing DNS record to Office 365, your old mail server will cannot use this domain name.

Hi Kyle,
after adding domain name and changing dns record to o365, how mailboxes will receive emails.
Points to note:1.) we imported the way of PST(we imported pst data not users mailbox) and i guess active users still on onpremises or not?
2.) changing dns record can stop receiving new emails?
Before import data, you need to create mailboxes on Exchange online first.
After importing data, you could verify your domain name on Office 365. In this way, new emails will be sent to Exchange online mailbox.

There are two ways you can import PST files to Microsoft 365: Network upload. - Upload the PST files over the network to a temporary Azure Storage location in the Microsoft cloud. Then you use the Microsoft 365 Import service to import the PST data to mailboxes in your organization.
