440 Login Timeout - Outlook Web Access

I started to play with Exchange 2007 in production enviroments. I had one problem recently with OWA. When user was trying to access https://exhub01.domain.local/owa the URL was rewritten to https://exhub01.domain.local/owa/auth/logon.aspx?url=https://exhub01.domain.local/owa&reason=0 and a "404 - File or Directory not found" error appeared in the IE window. To fix that I had to remove default owa (default folder) and create it back. Here is step by step instruction how to do that: 1. Use the Exchange Management shell and run the following:

a. Get-OwaVirtualDirectory -Server to check the settings in my case it was Get-OwaVirtualDirectory -Server exhub01

b. Remove-OwaVirtualDirectory -Identity in my case it was Remove-OwaVirtualDirectory -Identity "exhub01\owa (default folder)"

c. New-OWAVirtualDirectory -Name "owa (default folder)"

d. then restart IIS using iisreset /noforce

here is Microsoft commands reference http://technet.microsoft.com/en-us/library/aa998624.aspx

After IIS restart all stared to work and supposed ;-)
