That's what is more important than anything else

olApp = GetObject(, "Outlook.Application") will not find my Outlook started by Visual Studio
The instance of Outlook, started by VS is not available

I have two projects
The first is the Outlook project, adding features according to the need of the CRM system, like search, add appoinments etc. Everything works as it should and it is in production whith some 2000 users.

The second is the CRM system.

Earlier, I could start Outook from VB project, to be able to debug and see what is happening.
Then open the other project, who will communicate with the first project.

Both are Visual Studio (VB) projects.

Now, I cant create an instance of

olApp = GetObject(, "Outlook.Application"), it will fail, and therefore open a new Outlook.
Sometimes gives me a message saying that only one instance of Outlook can be opened.

This method of working has always been working before, but not now
Why cant I grab the outlook started by my project

Is it a Winwdows (10) Office (2016) problem
Are using the latest version 9 of add in express standard.

Thanks in advance

Hello petgre,

Your code started elevated (if VS is started via "run as administrator") cannot know about Outlook started non-elevated; similarly, your code started non-elevated cannot know about Outlook started elevated. This is by Windows design.

This shouldn't work; see my previous message.

I expected this to work.

This is expected.
