I have shared volumes with Acronis Files Connect (formerly ExtremeZ-IP), but when I connect from the Macintosh, I do not see the volumes listed, or they are grayed out.
If the volume is not listed, open Acronis Files Connect Administrator on the server, and view the Volumes window. The list of volumes includes status information about the various windows:
If the volume's status indicates an error, you should open the Windows Event Viewer, and select the "Application" section. There should be an indication of what kind of error occurred. Correct the error condition, and either restart Acronis Files Connect, or delete and re-create the volume.
If the volume's status is "Online", you should verify that you have permission to access the volume - if you have selected the "Hide Inaccessible Volumes" option in the Acronis Files Connect Settings panel, you will not see volumes to which you do not have at least read permission.
If the volume is listed but grayed out, verify that you have permission to access the shared file/folder.
To verify your permissions, select the directory in Windows Explorer, select "Properties" from the File menu, and then select the "Security" tab. Click the "Permissions" button to view and modify the access control list.
