I thought I had fixed this from a previous post but sadly not:

Client PC was being asked for password every hour or so in Outlook 2007. I used this link and client ran the fix :

http://support.microsoft.com/kb/956531

He has just sent this email I which he says :"Worse than ever no connection to the server and no boxes jumping up asking me for user name and password!"

He is using SBS 2003 and Outlook 2007

case 1: Remove all the saved passwords in the credential manager and the browser if he is using OWA.

Case 2: Check the user account is locked anywhere in the Lockout Status.if he is locked anywhere unlock the user.

now close the outlook and restart the outlook..

then it should work. if it pop's up password for the first time.please provide your password.

1) Credentials manager can be found in the Control Panel on the PC.

2) You would have to look in active directory under the user account for the lock out status.

- In addition to this, check to see if Outlook Anywhere is configured on the client.  If the user is on the same LAN as the server and do not work from home, disable this (Should be off by default).

Failing this, I would create a new outlook profile.

Are they on wireless or wired?
Do some ping checks to confirm that they are not being disconnected from the network.

Would it be  worth running a system restore? Outlook is showing as disconnected.

If I create a new profile do I have to import email files?

Client received this email


"Alert on SERVER at 25/06/2013 14:44:19

An account was locked out due to multiple failed logon attempts that occurred in a short period of time. This may occur if an unauthorized user attempts to gain access to the network.

For more information about this event, see the event logs on the server computer."


Is this to do with the disconnected problem in my post above?

Its down to something trying to connect using an invalid username and password to that account.  

Clear the credentials in credentials manager as suggested.

Also check to see if the client has any mobile devices etc that are setup to receive mail on that account that could be triggering it.  Ask them if they have changed their password recently.
