I've have a weird behavior with Outlook 2019 (Microsoft Office Home and Business 2019 Version 2105 Build 14026.20246 Click-to-Run) on a client's PC running Windows 10.
If she opens Outlook, starts a new email and then starts typing a name of a person she's sent emails to previously and nothing will appear, no quick list.
Then, she will close Outlook, restart it, repeat the same steps and sudden she has a list that she can pick from.
I did this over and over and over. The quick pick autocomplete list appears every second instance of Outlook.
I performed a Repair, it did nothing.
Has anyone seen this before?
Anyone have any ideas?
