I am migrating our public folders from Exchange 2010 to exchange online. I followed Microsoft's guide: https://technet.microsoft.com/en-CA/library/dn874017(v=exchg.150).aspx
The migration went well for all public folder except one. This is the error I get:
28/04/2016 20:52:19 [BN3PR11MB0225] Public folder could not be mail-enabled. The error is as follows: "No mail public folder was found in Active Directory with OnPremisesObjectId= I removed this part
28/04/2016 20:52:19 [BN3PR11MB0225] Stage: IncrementalSync. Percent complete: 95.
28/04/2016 20:52:19 [BN3PR11MB0225] Fatal error FailedToMailEnablePublicFoldersException has occurred.
I tried to mail-disable the PF (it did resolve other errors I had) – Error does not go away.
I ran the Sync-MailPublicFolders.ps1 – Error does not go away.
Has anyone ever had this error!?
Thank you very much!

Seems like you are on the right track. Microsoft has published a KB on this issue here: https://support.microsoft.com/en-us/kb/3050726
From the KB
Mail-disable all public folders that are mail-enabled in the NON_IPM_SUBTREE folder. For more information about how to mail-disable a public folder
To locate the system public folders, open the Exchange Management Console, go to Toolbox, open the Public Folder Management Console, and then expand System Public Folders. Mail-disable any public folder that has a mail icon next to it.
