Save the Export File on a Shared Folder

Using C:\ would imply saving it to the local machine the Acumatica instance is on rather than your local machine. 

Is your Acumatica instance installed within the local domain. If so you may be able to use the shared folder option using the Network Path on the Sharing tab in the folder properties but I don’t see how it would work if it is hosted elsewhere. If you have Google Drive or Onedrive the community post below may help.

Hello apallawala21,

The Error Code 1326 you are seeing is a standard Windows error that translates to "Logon failure: unknown user name or bad password." This means the credentials you entered in the Synchronization tab are being rejected by the destination folder's security.

Here are a few things to check to resolve this:

• Format of Login: If the folder is on a network domain, ensure the Login field is formatted as Domain\Username. If it is a local machine, try .\Username.

• Folder Permissions: Ensure the Windows user account you are using has "Full Control" or at least "Write" permissions specifically for the C:\Test\ folder.

• SaaS vs. Local: If your Acumatica instance is hosted in the Cloud (SaaS), it cannot directly communicate with a local drive like C:\. In this case, you should consider using a File Provider like OneDrive, SharePoint, or an SFTP server instead of a "Shared Folder" type.

• Password Update: Double-check that the password in the Synchronization tab is current and does not contain special characters that might be misread during the handshake.

I hope this helps you get your export working!
