Please can someone advice.. we have lots of excel file most are working fine. However we get a message on some that say..
REQUIRED PROPERTIES to save to server, correct the invalid or missing required properties
I have tried almost everything I know to fix this. So far the only method that works is to create a new file and then copy the tabs to it and upload again replacing the old file. As these files can be complex and some just 1 tab and little information it is a crazy job to do this and without knowing why or how to fix it correctly. Does anyone know what caused it and how to fix it?
