Hi,

I have a desktop to which I remote in via rdp using my laptops, tablets etc. (Username: MicrosoftAccount\myemail@outlook.com, password: mypass)

I want to give another user remote access to this desktop. So I added his email address (abc@outlook.com) via "Manage other accounts", enabled remote access for this email via "System Properties" --> "Remote" --> "Select Users"

Now, when he tries to log in using his email, Username: MicrosoftAccount\abc@outlook.com, password: HisOutlookPassword, via RDP, he gets error "the credentials that were used to connect to MyDesktop did not work. Please enter new credentials."

Anything I am missing? Does he need to physically login to my desktop for the first time?

Please help.

All OSes we use are Windows 8.1 Pro

Thanks, 
AbP

Hi, 

Please make sure that he is in the same network as your computer. 

If you're using Windows Firewall, follow these steps:

1.        Open Windows Firewall.
2.        In the left pane, click Allow a program or feature through Windows Firewall.
3.        Click Change settings.  Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
4.        Under Allowed programs and features, select the Remote Desktop check box, and then click OK.
5.        If you're using a different firewall, make sure the port for Remote Desktop (usually 3389) is open.

If this issue still persists, please post back the event log about RDP. 

Keep post.
