Add entries to the AutoComplete list

Outlook 365
The AutoComplete list is updated automatically after sending an email (see more about AutoComplete feature). To make it easier to work in Outlook, you can add useful email addresses to your AutoComplete list without sending emails.

To add addresses to the AutoComplete list without sending an email to the recipient, do the following:

   1.   On the Send / Receive tab, in the References group, click the Work Offline button:

Work Offline button in Outlook 2016   or   Work Offline button in Outlook 2016

Outlook displays the Working Offline status in the status bar and stops sending and receiving messages:

Offline in status bar Outlook 2016

   2.   Create messages to all recipients you need to add to the AutoComplete list and send them.

Notes: The AutoComplete list is limited to 1 000 entries for Outlook 2016. After reaching this limit, Outlook removes the entries you use the least to make room for new entries.

Outlook places all sending messages in the Outbox folder:

Messages in Outbox Outlook 2016

Now, you have all added recipients in the AutoComplete list:

   3.   Delete all messages from the Outbox folder to avoid sending them.

   4.   On the Send / Receive tab, in the References group, click again the Work Offline button to switch into the online mode.
