This first appeared three days ago.

I have removed, and then added, account 4-5 times, but still nothing happens.

I am able to send/ receive on WLM with the other accounts, but the account in question is "Default Account." I keep getting asked to provide logon information for both the specific account, as well as for the WLM account (and, this despite the fact that the WLM account is open, shows other accounts, and I'm able to send an receive on hose other accounts while in WLM).

I went to the Control Panel and did a repair on WLE; that did not help.

I can access this particular account (and send and received) at the Outlook website.
