    Hi @Alika Stricker ,

    I have performed many tests on my Outlook 365, Outlook 2019 and Outlook 2016, but the auto-completed list could display dropping down normally. So what's the version of your Outlook client(File>Office account>About Outlook), please first ensure that you have updated to the latest version of Outlook client.

    Does this issue occur only on your client, and whether other users in the organization could work normally? If it only occurred on your client, did this issue occurred only recently? If so, have you performed any specific operations before it(such as install any add-ins or programs), which may affect client functionality.

    In order to avoid the interference of any add-ins, it's suggested to restart your Outlook client in safe mode to check if the issue has any difference(Windows + R > type "Outlook.exe /safe">enter)

    If the issue still exists, considering corrupted Outlook client may also cause it, please try to repair your Outlook to check if it could work for you.

    If that's invalid, please provide us with more information about your issues, so that I could perform more targeted tests and provide you with more suggestions.

    What helped me is: Rollback like ManuelMedina instructed and disable automatic updates in Office 2016 / 2019 for now.

    Hi all,

    First of all sorry for the inconvenience caused to you.

    As I know, this is a known issue on latest version of Outlook 2016 and Outlook 2019--Version 2104 (Build 13929.20296), the current workaround is to delete/rename this value:

    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\DisableAutoCompleteUpdate

    But according to my research, it could work for some clients, but some couldn't, please kindly check if it could be helpful to you.

    If that's invalid, considering it could work normally on previous version, as another workaround, it's suggested to disable auto-update and revert your office version via command like below:

    C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=16.0.13901.20462

    I will continue to monitor it in latest version of Outlook client, and if there are any updates, I would post back. Also welcome other users who has any updates post here :)
