Using the Mail Merge Wizard Across a server


I’m trying to print labels from different spreadsheets across a sever, while also having a label printing template. I was hoping others could simply access the label printing document, add their spreadsheets to the mail merge wizard, and print away. But it seems the connection to the database file is lost every time the printing document is accessed on another computer. Can anyone help me with this?

Using Tortoise SVN sever network and Libre Office Write and spreadsheets.

Thank you.
