Outlook name cache not updating
Note: This document will help you locate the auto complete Stream_Autocomplete file associate with your Outlook account, for Outlook 2013 using Windows 7 and 8/8.1.
The path where the file is stored is C:\Users\*username*\App Data\Local\Microsoft\Outlook\Roam Cache.
The good news is getting rid of that address from your auto-c cache is simple no matter the Version of Outlook (2003, 2007, or 2010.) Just follow the steps below.
Solution: The fix is easy: Solution #2 is comparable to the “Nuclear Bomb” being that it will delete ALL your cached email addresses.
Note: If you are using the Deployment Pro product to automate the configuration of Outlook profiles, Autocomplete Lists will be migrated over to the new profile, as part of the process.
This feature saves to a file any typed email addresses even if the person is not in your Contacts folder.
Microsoft Outlook has some nice productivity features for email addresses called Auto Complete and Auto Resolve.
Each offers conveniences, but there are differences between the two.
It should only be used if you want to wipe the file clean or if you have corruption issues with your .nk2 file.
Once you delete the .nk2 file, then the next time you open Outlook it will automatically create a new .nk2 cache file, and Outlook will once again begin caching the email addresses you use.
This folder creates contacts for each new address a user sends email to.
