My recommendation is to complete the public folder migration steps. If not then the users which are on Exchange 2013 will get the popup message while opening the outlook after the Exchange 2007 is removed.

All mailboxes have been moved to Exchange 2013 for a few months now, and I'm finally looking to decommission the Exchange 2007 server. While I have a public folder database on Exchange 2007, it seems that it only housed the OAB data (which I understand doesn't matter anymore, since 2013 has it's own version), and had some items in a exchangeV1 folder (which I also believe to not be important, unless I'm mistaken). The company did not create any additional folders.<br />
<br />
I'm trying to figure out which set of instructions would be best for me to use to just get rid of the old public folder structure and create a new one on the Exchange 2013 server, with minimal issue. <br />
<br />
The Exchange 2013 databases all list the 2007 database as their public folder database. As far as I can tell, only the IPM_SUBTREE exists in my 2007 public folder.<br />
<br />
Thanks.

Decommissioning Exchange 2007 (move to 2013) - best way to remove public folders and start new

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
