How to fix error '440 Login Timeout' with Outlook Web Access

A common issue with Outlook Web Access is the 440 Login Timeout Error. Its not restricted to one version of Exchange either. Exchange 2003, Exchange 2007 and in some cases Exchange 2010 is affected.

The error occurs due to two accounts in active Directory: IUSR_(dc name) and IWAM_(dc name) which either gets locked, has their password expire


Note: (dc name) above would be the name of your domain controller.



Here's how to fix it:

STEP1

- Open Active Directory Users & Computers.
Expand the Users OU and right-click on the IUSR_(dc name) and click Reset password

- Reset the password to anything you'd like (the password however cannot be blank).

- Open this User Account's properties and verify that the account is not locked out. Also, make sure that Password never expires and User cannot change password are selected.

- Repeat the steps above for the IWAM_(dc name) user account.

- Once done, you can safely close Active Directory Users & Computers.


STEP2

-Open Internet Information Services. (You can do this by clicking Start -> Run and typing inetmgr in the command prompt window and clicking Ok)

- Expand -> Web Sites

- Right-click on Default Web Site and select Properties.


- Go to the Directory Security tab and click the Edit button under Authentication & Access Control


- Enter the new password for the IUSR_(dc name) account that you set according to the steps above and click OK.

- Enter the password again to confirm and click OK.


- Click OK again

STEP3

- Open a command prompt and type in the following commands in the exact as they appear below:

iisreset (press Enter)

cd c:\inetpub\adminscripts (press Enter)

adsutil SET w3svc/WAMUserPass (press Enter)

(Replace WAMUserPass above with the password that you set for the IWAM_(dc name) account as per STEP1 above)

c:\windows\system32\cscript.exe "c:\inetpub\adminscripts\synciwam.vbs" -v

iisreset (press enter)

Thats all there is to it!. It seems complicated, but it really isn't! Once you have all of this done authentication should work.
