Reason
OnePlaceMail defaults to using the currently logged in credentials (user's Windows credentials) to authenticate with SharePoint. If the user has specified non-default credentials in OnePlaceMail Settings, these will take precedence.
If the user account above does not have the correct level access to the specific SharePoint location you will receive these errors. As OnePlaceMail enforces SharePoint security, a user will require at least Contributor level of access to be able to upload files to a SharePoint list/library using OnePlaceMail.
Solution
Solution 1:
Confirm the user account can access the SharePoint location through the web browser user interface of SharePoint successfully.
If the user cannot access SharePoint through the web browser then you must modify the access permissions in SharePoint for the user account and try using OnePlaceMail again.
Solution 2:
In order for OnePlaceMail to automatically pass default Windows user credentials to the SharePoint server, the SharePoint site must be added to either your Local Intranet Zone or the Trusted Sites Zone in Internet Explorer.
Follow this procedure for adding a SharePoint site to the Trusted Sites Zone:
- Start Internet Explorer and open your SharePoint site
- Double click on the web content zone icon (located in the bottom right of your browser window)
- Click the Trusted Sites logo and then click the Sites"
