When we use the Office software to open some files that are saved in a network location, it can occur that the Office program is slow to run or even the program is not responding (hangs). This behavior is usually caused by the interruption of the network link when the Office program opens the file.
Operation Steps:
For Office programs that run slowly or even hang because of opening files on a network location, Microsoft has released a fix tool dedicated to fixing the problem, with links to the following tools:

We can also try to solve this problem by adding the Enableshelldatacaching key value in the registry:
First, click Win+r, enter "regedit" Return to the Registry Editor, click Ctrl+f, to search the following path key values:
Office 2003:hkey_current_usersoftwaremicrosoftoffice11.0commonopen Find
Office 2007:hkey_current_usersoftwaremicrosoftoffice12.0commonopen Find
After finding the above key value, right-click the right window blank, click "New"-"DWORD Value", and then order this value to enableshelldatacaching.
Finally we just right-click the value-Modify, change "value data" to 1, you can.
