To get around this issue locate the file path for the Export OASIS folder on the network. Right click on the folder and click on Send To > Desktop. From your desktop right click anywhere there’s not an icon, click on New > New Folder. Rename the folder to whatever you prefer.
Each time you create a new OASIS batch, go into the Export folder on the desktop, copy the file, paste it in your new folder on the desktop.
When you get connected to AT&T and you get to the part where you need to browse for the file, go to the new folder on the desktop, select and send your file.
