Computer Tip: Migrating Outlook 2010 autocomplete to another computer

Outlook automatically completing people’s names as you begin to type by using the autocomplete feature. Below is a step by step if you are planning of moving an Outlook 2010 installation from one computer to anotherĀ  or similar circumstances [probably work with Outlook 2013 as well].

  1. On the old computer, close Outlook.
  2. Go to C:\Users\%username%\AppData\Local\Microsoft\Outlook\RoamCache and note the name of the Stream_Autocomplete_****.dat name [the file will look something like Stream_Autocomplete_0_97CB663C6A2B8C4391E632034321F2F.dat.]
  3. Copy that file to where other files of the computer that will be migrated over to the new computer [i.e. My Documents or directly to a USB key or portable drive].
  4. On the new computer, install Office 2010.
  5. Open Outlook 2010. Create a new message. Insert a dummy Email address and auto-complete it [Alt-K]. Exit Outlook 2010.
  6. Go to C:\Users\%username%\AppData\Local\Microsoft\Outlook\RoamCache on the new compute.
  7. Make a note of the .dat file name. Rename it [suggestion: .dat to .bak].
  8. Rename the backed up .dat file to match that of the above so that the .dat file is the same as the original .dat file before you renamed it].
  9. Open Outlook.

Note: Every installation [or reinstallation] of Outlook, Outlook will change the digits in the filename.

Note: Autocomplete is just a cache to make life a bit easier. Outlook will eventually re-index itself. Soi this isn’t critical.

Note: Prior to Outlook 2010, Outlook used the .nk2 found in C:\Users\%username%\AppData\Roaming\Microsoft\Outlook.

Mini tip: To clear the cache, just run the command from the Run box: Outlook.exe /CleanAutoCompleteCache
