Migrating the PST of a mailbox to 0365.

Hi

We have exchange 2017 and we have built exchange 2013 and doing a Hybrid migration.
I have issues with migrating many mailboxes to 0365. Now I am thinking of exporting the mailbox of the users from exchange server to a .PST format and then migrate the mail box to the relevant users 0365 account.
Please post me tutorial to do this.
Thanks

Fastest way to do it without involving users (export from outlook) is use PowerShell Command

Run Exchange PowerSchell

New-MailboxExportRequest -Mailbox Username -FilePath "\\SERVER\Share\Username.pst"

Open in new window

for example for user TOM

New-MailboxExportRequest -Mailbox Tom -FilePath "\\SERVER\Share\Tom.pst"

Open in new window
