Export Cached Email Address From Exchange

Have a client that has MS Exchange with Outlook 2010 on the clients. They are migrating to a new 2012 R2 server with no Exchange. Its a small client that does not need the Exchange and want to save money. I am just exporting all email/contacts etc from Exchange into a .PST file on the PC. They are just using POP accounts so no real issue. I point everything to the new PST file and remove the Exchange connector. Once I remove the Exchange connector all the cached email address’s are lost.If they were using Outlook 2007 or 2003 then the cache email’s would be in the .nk2 file and everything would be fine. Since its Outlook 2010 the cached email address’s are stored on the Exchange. What I had to do is Export the cached email address’s from Exchange to the PST. To do this I re-added the Exchange connector. Can see the cached email address. I then followed this MS Article on export and import. I exported from the Exchange profile (.ost) and then imported into the new PST. After following the instructions and then removed the Exchange connector everything was fine.

The main part of the article I used is the following:
