Exchange account Cant login untill Unlocked

[2097]

Getting some stange things happening on one of my exchange accounts !

Basically .. On our admin network one user can never login to exchange 2003 weboutlook in the morning . After 2 attempts it locks the account ( even though every user is set to 5 invalid logins then lock) . After i unlock the account it then proceeeds to login fine !

The exchange server is on the curriculum network and i can login into the account fine in the morning from this network .

The only thing that has happened is i changed the Admin users login/account name .


any one got any recomendations to check ?

Many thanks

1. There's something on the network that has these credentials cached that's attempting to use them and locking out the account.
2. I suspect there is nothing wrong with Exch as this issue only occured after you changed the password.
3. Use the account lockout status to see where the lockout are occuring - Download Details - Microsoft Download Center - Account Lockout Status (LockoutStatus.exe)

thanks for the help Sukh

I now suspect its something to do with the proxy . If i access the site via the proxy it does the above , if i add it to the exclusion list 'mail.school.com' it looks like it works ok. Only tomorrow will tell.
