If you are having any of the issues below when using your Project Professional connected to Project Online, I have the solution for you!

Microsoft Project
Unable to display Projects from the Project Web App.
Possible reasons:
- You have chosen to work offline.
- General network connectivity problems.
- The Project Web App is currently not available.  
- You do not have sufficient permissions to open project(s) from Project Web App.

If this happens again, contact your administrator.

Microsoft Project
Project was unable to establish a connection with "https:// [tenant] sharepoint.com/sites/pwa".
This could be caused by a loss of network connectivity or inadequate permissions to connect to Project Web App.

Below it is how you solve the problem:

• Click on the Windows button
• Search for “User Accounts”
• Click on “User Accounts” for Control panel

• Click on “Windows Credentials”

• You will see several credentials here…
• Don’t’ worry… I will show you which ones we must delete.

• If you work in the PPM or Project Online consultancy business, you will have A LOT to delete!!!
• If you are only working with few PWA instances or tenants it will look better or smaller…
• You need to delete all credentials starting with “MicrosoftOffice16_Data:ADAL”

• Before you start deleting, close all Office programs and browsers you have opened.
• To delete the credential, click on the arrow in the right side
• Click on “Remove”
• Then “Yes”
• This will delete the credential for the local machine.
• Repeat this process for all credentials starting with “MicrosoftOffice16_Data:ADAL”

• After you have deleted all
• You will see something like below:

• Open Microsoft Project Professional again
• Select your “Project Web App Account”
• Click “OK”

• You will be requested to re-type your username
• Type the email of the account you would like to use to open the Project Online account

• If you are using this email in more than one Microsoft account.
• Like LIVE ID and Azure AD, you will need to choose each one to use
• I’m using the “Work or school account”, which is Azure AD.

• Type your password.

• You are now connected

• And you will be able to open your projects from Project Online again in your Project Professional!

Not a fun post, but VERY USEFUL! 😊
