Migrating Outlook 2010 Autocomplete to Outlook 2013

1. Run Outlook 2013, allow it to finish loading, then close it - no need to wait for it fully synchronize if you have a large mailbox.
2. Open C:\Users\username\AppData\Local\Microsoft\Outlook\RoamCache
3. Look for files named Stream_Autocomplete.dat  and note the latest one (this is the target) and the largest one (this is the source).
4. Make a backup copy of both files, I placed mine in C:\temp.
5. Go back to C:\Users\\AppData\Local\Microsoft\Outlook\RoamCache and rename the source file Stream_Autocomplete.da~ by replacing the "t" with a "~".  Before you commit the change, highlight the entire name before the period and copy it with Ctrl+C then commit the change.
6. Rename your target file by pasting the source file name over the target file name.
7. Run Outlook and feel the joy.

Why didn't Microsoft make this an automatic function like they did in prior versions? 0_o
