Issue

If you find that your custom scripts are not getting executed and the object in question has an ampersand in the object name then you might be encountering this issue. Below is the output of ocum-script.log showing a failure to execute on a "Qtree Space Nearly Full" event.

The ampersand (&) character is not allowed. The & operator is reserved for 
future use; wrap an ampersand in double quotation marks ("&") to pass it as 
part of a string.

In this example we are testing a Qtree. PowerShell is not able to handle the ampersand. From our testing we know that this issue can occur for both Qtrees and CIFS shares, however, this issue might exist for other objects.
