Outlook display name not updating

The usual problem when autocomplete stops working has something to do with your PST file.The first thing to try is to repair the PST file and see if the autocomplete entries come back or stop resetting.Note that this program will automatically detect if you have Outlook installed and will load up the cache file for you if it’s stored in the default location.You should see the autocomplete list instantly: If it didn’t open or you can’t open it manually, then you need to create a new cache file and replace the current file.You can do this by going to the following location on Windows 64-bit and running the file.Note that the path may be different depending on your version of Office.

Check out the above Microsoft KB article on how to do this.

In some instances, to get this working again in Outlook, you may have to clear out the Autocomplete cache.

If everything is gone already, then this won’t matter, but it should help with the problem of the cache resetting over and over again.

For the file name, just select the current file that you will be replacing. You can also get a lot more information about Outlook Autocomplete from the Microsoft support website.
