Exchange Online User No Access To OnPremise Public Folders

byt3 asked
Last Modified: 2018-02-02
I followed the process here:


At the end there is an Important note about an exchange online user getting this error (which I am getting):

Cannot expand the folder. The set of folders cannot be opened.
Network problems are preventing connection to Microsoft Exchange.

I moved a mailbox from On-Premise to the cloud, which left a 'Remote User Mailbox' object behind, so the user has an exchange object On-Premise. I tried deleting that object and created a MailUser object instead, but I still had the same issue (I since changed it back).

Any troubleshooting suggestions?
