Resolving MAIL360 Server - Cannot deallocate or add a partition


User does the correct steps needed to do the partition de-allocation in MAIL360 Server, and it says it did it successfully, but them shows the same partition still in existence. 


For some versions of Internet Explorer, 'Compatibility Mode' needs to be enabled 


UPDATED: December 20, 2018
If this problem occurs, try enabling 'Compatibility Mode' in Internet Explorer.

Additional Information-
It was also found by another customer that was using Internet Explorer that when he clicked the red X box to remove a partition, there was no response.
Also, he could not seem to be able to add  a  numbering partition. 
He added both the IP address, and the Server name (URL), to the Compatibility View, and it seemed to solve the issue.
