When using the Export Wizard, exporting to Excel takes several minutes to show the path where to save the file to, when on a network drive.
If there are no access issues or network latency within the environment, please check the contents of the target directory. If there are large files, or one file with a very large file size (e.g. 1GB) in the directory, please move/remove the file first and re-test the Export Wizard.
