Can help me to resolve this issue. I have tried many methods but can not resolve it!

Thank you very much.


You need to set the OAB virtual directory for external users. You do that by running the following command (with the proper url. Probably your OWA url):

Get-OABVirtualDirectory | Set-OABVirtualDirectory -InternalURL https://exchange.domain.local/OAB -ExternalURL https://mail.domain.com/OAB

  • Hi, I can confirm my externalURL is right. But it still will come out the same error. Any other suggestion? Thanks! – e0594cn Jan 4 '11 at 11:26
  • Try to hit the external URL from a web browser from outside your office. You will likely get an error page. Let us know which error page you're getting. – Jason Berg Jan 4 '11 at 15:07
  • Hi ,it will come out one page and ask me to key in the user name and password! After typing in, it will come out the below msg: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. – e0594cn Jan 5 '11 at 12:01
