Summary

This article contains an overview of the Microsoft Outlook AutoComplete list (also known as the Outlook Auto-Complete list). In addition to describing the feature, this article contains more information and step-by-step instructions for advanced users to manage the list.

More information

Outlook maintains the AutoComplete list. The list is used by both the automatic name-checking feature and the automatic completion feature. The AutoComplete list, also known as the nickname cache, is generated automatically when you send email messages from Outlook. The list contains SMTP addresses, LegacyExchangeDN entries, and display names for people to whom you have sent mail previously.

Note

The AutoComplete list for Outlook is specific to Outlook and is not shared by Outlook Web App (OWA). OWA maintains its own AutoComplete list.

The following sections provide information about the AutoComplete feature.

Limit to the number of entries

Outlook limits the number of entries that you can save in the AutoComplete list. After you reach this limit, Outlook uses an internal algorithm to determine the best names to remove from the list. It does this based on a usage weighting. So, you may find some names unexpectedly removed from your nickname cache. There are two general approaches that you can use to avoid this situation:

You can proactively remove AutoComplete list entries that you no longer need. This is the preferred approach. For more information about how to do this, see the How to remove AutoComplete list entries one at a time section.
You can increase the limit for the nickname cache. Because this configuration is untested, we don't recommend it. If you have a larger nickname cache, you could also lose a larger number of cached entries if your nickname cache becomes unusable because of corruption. For more information about how to increase the limit, see the How to change the limit for the AutoComplete list section.

The limits are as follows:

Outlook 2016: 1,000 entries
Outlook 2013: 1,000 entries
Outlook 2010: 1,000 entries
Outlook 2007: 2,000 entries
Outlook 2003: 1,000 entries

How to enable the AutoComplete feature

How to import .nk2 files into Outlook 2010, Outlook 2013, and Outlook 2016

Microsoft Office Outlook 2007 and earlier versions store the AutoComplete list in a nickname (.nk2) file on the disk. Outlook 2010, Outlook 2013, and Outlook 2016 store the AutoComplete list as a hidden message in your primary message store. Outlook 2010, Outlook 2013, and Outlook 2016 let you import the older .nk2 files.

For more information about how to import .nk2 files in Outlook 2010, see Import Auto-Complete List from another computer.
