Suggested Contacts folder empty

Hi!

I have a problem with the suggested contacts folder.

The folder is always empty but i think it should keep the emails from the autocomplete when writing an email.

Does anybody know how to solve this problem?

Thank you.

Best Regards

@klipp WebApp does not use this folder.

Some ideas how to use it: https://jira.kopano.io/browse/KW-1003
