Outlook Web Access - Some users getting 404 errors.

Hi All,

I have OWA running of Exchange 2007 SP1 & IIS, for most users all is ok, but for a few (who used to be able to access but now cant) they are being displayed page not found - 404 - errors.

This is perplexing me, where should I be looking to troubleshoot this?

Thanks

Check if the internal OWA access URL is pointing to the correct IP and that the external access URL and internal access URL of OWA is correctly mentioned in the Exchange Server. Also, try putting in a static entry in the local host file to rule out the possibility of DNS issues.

Hi, thanks for your replies.

I have looked through all of those articles and checked the settings over and they seem to be ok.

At the moment I, and most other users, can access OWA both internally and externally - it is just two users that are getting the 404 errors, which made me think it may be a permissions issue?

Does the DNS correctly resolve to the OWA URL for these two specific users? Try setting a static entry to the OWA URL in their localhost file and see if that resolves the issue.

Hi All, yes the DNS is resloved correctly.

Interestingly, all users (including those affected) can access OWA externally, it is only when they are on the corporate network that the issue occurs..

Hi, it was a mess up between DNS & external vs internal DNS records.

Thanks
