Auto Complete Suggestion name not working

[BOOBALAN.V]

Dear Community,

I removed all contacts name and then i saved the contacts from mail attachment. Then if i trying to enter the name in TO: field its not automatically suggesting the contact names. But Auto name suggestion is checked in Advance settings. I am using Outlook 2016. Kindly help me to figure out this issue. Thanks.

I believe the auto-complete function is based on previously used entries. If you have cleared out all previous entries, Outlook has no history to make any suggestions from.

Dear sir,

Thank you so much for this link. Now only i resolved this issue. Problem is a file name is called Stream_Autocomplete_0_39EC2E54B9DF1E45A65ED5A38EF8E538.dat. I just restore all contact by using nk2edit.exe file. This is the only effective method. Other methods doesn't work. Thank you so much sir. Working perfect.

You need to be adding these addresses to your "Contacts" which is separate from the Nick name list.
