THE INFORMATION IN THIS ARTICLE APPLIES TO:
Folder Monitor Event rule set to move files to a network share is failing at a certain time of day, getting error code 80070020. It doesn’t always fail.
The error code means that the remote share is not available.
In the Folder Monitor Event Rule, in the Monitor Folder dialog box, enable the Scan for files option. This will ensure that, if the initial attempt fails, EFT will try to access the shared folder again at a later time. When the remote share is available, EFT will be able to execute the Event Rule.
