I just reinstalled my computer but did not save the nk2-file to maintain my autocomplete list.
Is there any way I can quickly fill it with all my contacts at once instead of waiting for the list to rebuild itself again?
You can directly fill the list again by creating a new message addressed to all your contacts at once. There is no need to actually send this message.
- Create a new message.
- Press the To… button.
- Select the contact list in the right top corner from which you would like to add the contacts from.
Examples; Contacts folder, Global Address List (GAL) or a contacts folder in a Public folder.
- Select the first contact.
- Scroll all the way down to your last contact.
- Hold the SHIFT button on your keyboard while clicking on the last contact to select them all.
- Press the To –> button to add them all to the To… field.
- Repeat step 3 to 7 if you have contacts in additional lists that you would like to add.
- Press OK to close the dialog and to return to the newly created message.
- If you are using Outlook 2007 or previous, close the message and press No when prompted to save changes.
For Outlook 2010, Outlook 2013 and Outlook 2016, you must send the message to actually store these addresses in the AutoSuggest cache. However, by placing Outlook in Offline Mode first via the Send/Receive tab, you can easily prevent it from actually being sent by removing it from the Outbox and then place Outlook back online mode.
Now when you address a new message the AutoSuggest/Auto-Complete feature will pop-up again.
Some additional notes about the AutoSuggest/Auto-Complete cache;
- The maximum number of contacts that can be cached is 1000. If you have more contacts than that, not all of them will be added.
- See this post in case you want to remove certain addresses from the AutoSuggest list again.
- See this post for alternative methods of automatically resolving names from your Address Book.
- When using Outlook 2002, after step 9, you must click the Check Names button before it will write the names to the cache.
- Outlook 2010 no longer works with an nk2-file but with a special hidden message, a Stream_AutoComplete file and the Suggested Contacts folder.
- Outlook 2013 and Outlook 2016 don’t have an nk2-file either nor does it have (or use) a Suggested Contacts folder and only stores it in the special hidden message just like Outlook 2010.
