How to recover a deleted contact from the autocomplete list?

Hi @PhilK

For our better research, please provide more information about this case:

What is your account type?

Can't you recover the others if delete them?

How do you deleted the autocomplete list? If this is the deletion method shown in the following figure, it won't prompt. If you want to unhide the contact, send an email to the contact by replying to the old message or typing the full email address in the new message. After about 24 hours, the contact is unhidden from the list of suggestions. More information, see: Manage suggested recipients in the To, Cc, and Bcc boxes with Auto-Complete - Microsoft Support.

Additionally, you can try the following methods to clear the AutoComplete list:

1. Select Start, and then select Run.
2. Type Outlook.exe /CleanAutoCompleteCache.

Note: If Outlook is not installed in the default location, you must point to the path of Outlook.exe.

For more details, you could refer to: The Outlook AutoComplete list - Outlook | Microsoft Learn.

Hope this helps!
