Hello,

In my Exchange Environment I have two servers, Exchange 2007 and Exchange 2013.
My public folders located on Exchange 2007 and my mailbox located on Exchange 2013.
Once I click to the public folders I receive and error.
'cannot expend thee folder. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance.'

At the same time user that his mailbox located on the Exchange 2007 can acsess the public folders.

Thank you.

There is a huge difference between the Exchange 2007 Public Folders (or legacy public folders) and the ones introduced in 2013. The Public folder DB is gone in the newer version - "modern" Public Folders are now treated as mailboxes and for your Ex2013 mailboxes to access them, you might need to migrate them to Exchange 2013.
Here is a quick article about migrating legacy public folders to a newer version. If you need more information - ask away.

Agree with above. Public folder is completely re-engineered in Exchange2013. You will have to move to Exchange 2013 and enable PF on mailboxes if not enabled.
