If you would like EPDM to manage your toolbox, You need to SolidWorks Data folder into the vault.
Please refer the EPDM Administration guide on how to configure the toolbox within the vault.
Hope this helps!
We have found it easier to not put the Toolbox in the with all the issues, we first had.
But to each is it's own but we've had no issues with it outside of the vault.
I don't want to EPDM manage the toolbox.. We have created a "Toolbox elements" folder inside the EPDM, but that is only for the "Toolbox" created files..
The problem is, when my collegue want create a toolbox element, the Toolbox try to create the file inside the EPDM, but in the toolbox settings we set a directory outside the EPDM.
