Access Legacy Exchange 2007 Public folders using Outlook 2016

Hi,

I wanted to clarify something I just read on the internet elsewhere.... Can outlook 2016 access legacy public folders on exchange 2007? I have worryingly read it cannot as not compatible and also the same with OWA.

In our environment we have setup legacy exchange 2007 and 2013 running side by side, 2007 has a load of on-going public folders which users on Exchange 2013 will still need to access.  When attempting to access public folders using Outlook 2016 I receive an error "The set of folders cannot be opened. Network problems are preventing connection to Microsoft Exchange", I have configured a proxy mailbox on exchange 2007 as detailed in https://technet.microsoft.com/en-us/library/dn690134(v=exchg.150).aspx

If I open an Exchange 2013 mailbox using outlook 2010, I am able to successfully access public folders on 2007 so the proxy mailbox for public folders appears to be working.  Doing the same with 2016 fails...

We are forced down the root of buying Office 2016 now for new builds so I'm hoping that someone out there has a way around this? Migrating everything to 2013 is not currently possible and we are looking to move away from public folders for new projects etc.

Anyone out there with some help/advice would be much appreciated.

Thanks

Dan
