I did not find an existing API to directly clear the cache, but we know the location of the cache:
C:\Users\<username>\AppData\Roaming\Microsoft\Teams
We can delete him in this way:
System.IO.DirectoryInfo di = new DirectoryInfo("YourPath");
foreach (FileInfo file in di.GetFiles())
{
file.Delete();
}
foreach (DirectoryInfo dir in di.GetDirectories())
{
dir.Delete(true);
}
There are two things to pay attention to.
One is that this program may require administrator rights to run, and the other is that Outlook and Teams have a certain degree of integration, so you need to exit both Teams and Outlook to delete successfully.
