Hello
There was a patch due to address this but unsure whether installed yet.
Also read that cleaning cached passwords has resolved it for some.
Can you try to Clear Cached Passwords
The first thing you need to do in order to fix your issue would be to clear your cached passwords located in the Control Panel. Here’s how to do it:
Go to the Start Menu and open up the Control Panel.
Set the View By, located under the address bar on the right-hand side, to Large Icons.
Navigate to User Accounts
On the left-hand side, click on ‘Manage your credentials’
Select the credentials for Lync, Outlook, and Microsoft in both the Windows Credentials and Generic Credentials.
Click on Details and then select Remove from Vault.
Exit the Control Panel and then restart your system.
OK. This is Windows 10. I do not see a "Control Panel". There IS a settings but on that there is no "View By". If I ignore that and just click on "Accounts" it also leads me nowhere consistent with the next steps. Help!
