Hi Aflatoon,
Sorry I missed that.
The user gets a VB Runtime 1004 error - Method 'Save' of object '_workbook' failed.
So far I have:
1. added the network path to the Trusted Location,
2. enabled all Macros
3. Checked "Trust access to the VBA project object model"
4. Unchecked 'Remove Personal Information from file properties on save'
