Welocme to Microsoft QnA!
I understand that your users are leaving Office during Office hours and when returning the Mapped Drives are gone
You want to be able to reconnect them a easy as possible withou having to log off log on again
I can think some solutions :
First of all , have you tried the persistent option :
net use X: \server\share /persistent:yes
For this i am not sure if it wil work but taken from here it should
Manual User Click a Script :
Create a Script that users hit when returning that reconnects the drives :
net use X: /delete
net use X: \server\share1
I hope this helps!
