Send-AS hybrid public folder
Hi,
I have an Exchange 2013 in configured in hybrid and have public folders in hybrid mode also.
I have migrated some users to O365, now they cannot use send-as on mail enabled on-prem PF.
Is there way to solve this? They had this before migration and it was working.

If this is not supported, I have successfully found a workaround that makes Send on Behalf work anyway, so I'd be happy to share how to achieve this in a Hybrid scenario.
If a user needs to send on Behalf of a Public Folder, which resides in on-premises Exchange in the current Hybrid configuration, the following steps are necessary:- Ensure that the user has the permissions assigned in the On-Premises EAC:
Public Folders > *Your PF* > Edit > Delivery Options (Send As or Send on Behalf) - In ADUC, find the Active Directory object corresponding to the Public Folder. It would have the same name as the public folder.
- Open Properties > Security and Add..., pick the user and Allow Send as permissions on the PF object, then save.
- Connect to Office365 through the Exchange Online PowerShell Module and execute the following command:
Set-MailPublicFolder "PrimarySMTPofyourPublicFolder" -GrantSendOnBehalfTo "UserUPN" - The user with their Office 365 mailbox will now be able to Send on Behalf of the Public folder
So far, I only needed to set up Send on Behalf and not Send As permissions, but I'd expect the implementation to be nearly identical apart from the PowerShell command.
I believe the cmdlet for Send As would be:
Add-RecipientPermission -Identity <publicFolder> -Trustee <UserUPN> -AccessRights SendAs- Ensure that the user has the permissions assigned in the On-Premises EAC:
