In Survey123 Connect for ArcGIS, if an .xls or .xlsx form (XLSForm) file that originated from a source other than the local computer is used to create a new survey, the survey is created but Microsoft Excel may display the following error upon launch.
Error: Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space. • To make more memory available, close workbooks or programs you no longer need. • To free disk space, delete files you no longer need from the disk you are saving to.
Although the error message indicates or suggests a memory or disk space issue, because the .xlsx form comes from an alternative source (another computer), Microsoft Excel blocks the file from being opened through Survey123 Connect for ArcGIS.
Security: This file came from another computer and might be blocked to help protect this computer.
