Outlook 2010 no longer suggests email address names in To field
By default Outlook 2010 caches email addresses that you have used when sending out emails. In Outlook 2007 these addresses were stored in %USERPROFILE%\AppData\Roaming\Microsoft\Outlook\*.NK2 . In Outlook 2010 they are now stored in a file called: %USERPROFILE%\AppData\Local\Microsoft\Outlook\RoamCache\Stream_Autocomplete_*.dat .
An issue I have seen is when Outlook 2010 is closed, the Stream_Autocomplete_ .dat file deletes. When this happens, Outlook will no longer auto-complete your email addresses names. To correct this issue you simply have to toggle the option of using the Auto-Complete List off and back on again.
Outlook 2010 > File > Options > Mail > Send Messages >
Press Empty Auto-Complete List (just for good measure)
Uncheck Use Auto-Complete List to suggest names when typing in the To, Cc, and Bcc lines
Exit Outlook 2010
Re-open Outlook 2010 and Re-check the above option and OK it and exit Outlook
That has solved the issue for me and I have never had to rebuild the mail profile.
