allowing Exchange Online users to see on-premise public folders?
Hi,
Yes, it is still applicable for Exchange 2016 as well. You don't have to mail-enable all your public folders for accessing them from an Exchange Online mailbox. The synchronization of mail-enabled public folders is only for mail flow purposes, like that your users can see them in the GAL.
The Set-OrganizationConfig determines the public folder (proxy) mailboxes to get access through Autodiscover to your on-premises organization, right.
Referencing this document: https://docs.microsoft.com/en-us/exchange/hybrid-deployment/set-up-modern-hybrid-public-folders which I have been told is applicable to Exchange 2016 also. I am confused on these steps as i have found them not to work, so maybe I am doing something wrong so et me break down what I am doing step by step
I download the script listed in that document and place if on my exchange server:
Sync-MailPublicFolders.ps1
I then run Sync-MailPublicFolders.ps1 -Credential (Get-Credential) -CsvSummaryFile:sync_summary.csv
I then go to Exchange online powershell and run
Set-OrganizationConfig -PublicFoldersEnabled Remote -RemotePublicFolderMailboxes PFMailbox1,PFMailbox2,PFMailbox3
where PFmailbox is the name of the mailboxes on-premise
this results in absolutely nothing happening..
It seems good but it can take a couple of hours.
If you connect from an external network, make sure MAPI/http is configured and published correctly. The Autodiscover process from your Exchange Online organization will "find" the on-premises public folder mailboxes you configured in the Exchange Online Set-OrganizationConfig.
If you are using alternate login id, which means your UPN is not your primary smtp address, make sure modern authentication is enabled in Exchange Online for accessing public folders in your hybrid environment.
