This issue I have is this command (Step 5.2, a): -
Get-Mailbox <PublicFolder_Administrator_Account> | Select-Object LegacyExchangeDN
We've migrated all user mailboxes to Exchange Online so running this command doesn't work because there is no admin account with mailbox left on the legacy exchange server! At the very begining of the documented procedure under "What do you need to know before you begin?" It states "Before you migrate your public folders, we recommend that you first move all user mailboxes to Microsoft 365 or Office 365 and Exchange Online"
So following this to the letter makes it impossible to run that command.
If I just lookup the LegacyExchangeDN for my admin user I get different results depending on whether I check the value in AD or Exchange Online. Which one do I use?
Do you need to keep an admin account on the legacy exchange server for this to work?
