Hello @Gherca,Marius,
Welcome to Microsoft Q&A forum.
Will it work, if you try to clean NuGet cache(Tools > NuGet Package Manager > Package Manager Settings > Clear All NuGet Storage) and leave only nuget.org(https://api.nuget.org/v3/index.json) package source(Tools > NuGet Package Manager > Package Manager Settings > Package Sources) then try to install the Microsoft.Office.Interop.Outlook package again?
Hello @Gherca,Marius,
We have not heard from you for a couple of days. Does the same exception appear after you clean the nuget cache and leave only nuget.org package source?

Not sure what your nuget\ thing is here. Go to Package Manager Console in Visual Studio. At the prompt type Find-Package Microsoft.Office.Interop.Outlook and show us what the results are.
Under the Package Source combo at the top of the console show us what sources you have configured.
Still within the console type $host and show us what the output is.
To confirm you have a project open and it is targeting NET 4.8.1?
I opened a new solution and I
Clear all NutGet stockage
and checked
Allow format selection during the first package installation
I installed the package.
I opende my solution and I was able to install the same package.
Now, Before installing any package I go in other solution always opened, with no code, I install the package, I switch to my solution, clear all NutGet stockage and I can add the package. Make any sense!? THX for your help guys.
