Problem

Office 365 - winrm.exceptions errors occur when trying to restore to a PST (Export to PST) file.

Example:

winrm.exceptions.InvalidCredentialsError: the specified credentials were rejected by the server

Solution

  1. First, make sure your Windows machine credentials in Node Configuration -> Cloud Agent are correct.

2. On the machine where vprotect-node is installed, check the operation of winrm for the Windows computer that is used to export PST files. You can do it as follows:

Make sure you have the pywinrm library installed.

sudo pip3 install pywinrm

Go to the python environment.

python3

Import the winrm library.

import winrm

Create a session with the Windows machine.

Try to execute and display some command on a Windows machine.

Result when winrm works fine:

If you see an error when trying to connect via winrm, most likely winrm on the Windows machine side is configured incorrectly.

Example:

3. Go to your Windows machine and run the following commands in the PowerShell console.

 

Then from the Node machine again check if winrm is working properly.
