Outlook is one of the most popular platforms for everything related to messaging, contacts and other elements that involve contact with coworkers and more, that is why Outlook integrates many functions and one of them is the auto-complete list. This is a list that is used in the automatic checking feature of registered names in Outlook and is also used as an automatic completion method..
Autocomplete, or alias cache, is created automatically when sending email messages from our Outlook account, it stores SMTP addresses, LegacyExchangeDN entries, as well as the names of the contacts to whom we have sent emails in order to facilitate the shipping process.

Microsoft has had a limitation in the autocomplete list, these are:
- Outlook 2016: 1000 entries
- Outlook 2013: 1000 entries
- Outlook 2010: 1000 entries
