I have several customers who request "Can we view our public folders in Exchange from Sharepoint?" They do not want to migrate to a SharePoint calendar for whatever reasons.

I have been working on this for some time and have it working (almost) flawlessly.

I have a publicly accessible WSS3.0 site using SSL.

I have a publicky accessible OWA site using SSL.

When the user (either internally or externally) access the WSS site and logs in they see two Web Viewer parts on for a PF task and one for a PF calendar both at this time have the OWA logon field.

User signs in to either or both the PF task and PF calendar.

The PF task comes up fine. No errors and works fine as far as I can tell.

The PF calendar comes up, but with an error "Outlook Web Access has encountered a web browser error". You can click OK and it opens the calendar just fine. However, each time you cahnge the view from week to work week or month it splashes the same error. Again clicking OK gets you past the error, but it is very annoying and at this point not deployable to a client. I have a copy of the error code so if anyone (hopefully) wants to see it I can e-mail it to them upon request or post.

Now before someone says "this is an OWA" issue (which it may be) I can use the same exact URL links I am using in the web viewer and paste them manually into a browser session, logon to OWA, and it works flawlessly. No errors from either PF. It only occurs when launched from a Sharepoint session. This works internally or externally.

Has anyone else got this working (I can't be the only one wanting to view existing Exchange PF calendars through a Sharepoint viewer)? Any help would be greatly appreciated.
