Issue
You receive the following error in Worksheet when attempting to save your file on the network.
Solution
This solution will need to be implemented by your network administrator. This error can occur if the network you are saving to is a mapped drive letter established by Group Policy. If GPO is set to Replace mode, this can lead to the mapped drive connections being deleted and put back while the file is in use on the network, which will lead to the error. We recommend setting the GPO to Update mode to avoid this problem.
Workaround
If the error appears, you can do a File, Save As… and correctly save the file under a different name.
