KES 11 not registering in Windows Defender fast enough

we are using KES on our Windows 10 Enterprise 1809 clients (Intel i5-7500T, 8GB RAM, SSD). AntiVirus signatures are up to date. After turning the computers on and logging in we automatically start Outlook after another program. So Outlook is started after around 30 seconds after logging in. Once Outlook opens the following warning appears ("A program is trying to access email address information stored in outlook..."):

We believe this happens because Kaspersky has not fully started/announced itself at this point. If we check the Windows Defender settings, Kaspersky is not registered with "Virus & threat protection" and "Firewall & network protection" yet:

After around 90 seconds (!) Kaspersky is registered in the Windows Defender tab and the warning in outlook dissapears after accepting it until the next restart of the computer:

Something similiar has happened before (in january). Back then Kaspersky did not udate antivirus signatures on some clients and the warning popped up because of that. This was resolved and did not happen again. This can't be the issue this time however, since signatures are listed as up to date.

What can we do to fix this behaviour?

Thank you!

Are you using Windows 10 v1903? In that case you have to update KES to, it's a known issue.

thank you for your replys!

I just updated KES to but the issue still persists.

The issue is happening on Windows 10 v1809 and on Windows 10 v1903.
