Public and File Access in Exchange 2010 and OWA

Just want to get one thing clear on this. I have read and been told this feature has been removed and there is no Documents button anymore in OWA. Does this mean that all the settings on the Public Computer and Private Computer tab of the Default OWA policy at the Org level and individual CAS server settings on the Outlook Web App tab mean nothing anymore?

Do any of these settings refer to attachments in emails in OWA or was it just for file access which you apparently cannot do anymore.  We use the default OWA policy for all our users which I believe overrides all the settings on these tabs.

Just need to know because if I have to make a change or impose a restriction, I need to know where to modify it. I am hoping that since we use the Default OWA policy that this overrides everything else and I just need to change it there.

What I am most concerned about is the setting under both Public and Private Computer File Access called "WebReady Document Viewing". I am not sure if this also refers to email attachments that are sent to users or is it just File Access. It's so confusing.

We use the Default OWA policy for all our users which contains all these settings so I would like to know if this policy overrides everything else making the settings in the Console a moot point. For the longest time I assumed that the Default OWA policy had the last say so any changes needed to be made there.

Just email attachments. Documentation shows that it's also for shared files, but looks like the Exchange 2010 team didnt follow up with that. Once of the links mentioned there was a rumor that it (direct file access) would be re-instated in SP1 but it was never the case.

So this setting is only for file attachments in OWA.

OK. Last question. Since it does apply to attachments and I am using the Default OWA policy which has to be applied manually, where do I edit the setting? What I thought was if you did not use the Default OWA policy (Not assigned to users by default), then the settings you configure in the EMC would apply, but if you did use the Default OWA policy, then you would make the changes there.

Check out this link. It explains it a little more.

For your case, you apply the policy on the OWA virtual directory. The link I mentioned on my previous comment shows you how to do it via EMC and Shell.

Thanks but I already read this. In fact, its right out of Tony Redmonds Exchange 2010 Inside  Out book which I am reading. The first few lines state it appears that if you are using the Default OWA Policy, it overrides settings in the EMC at least for the Segmentation tab but I wanted to know about all the other settings on the Public and Private Computer File access tabs.

I am guessing it does. It appears you have a choice. You can either use the settings in the EMC for those that actually apply or use the Default OWA policy Microsoft gives you but does not automatically apply to new users. You have to add it manually. This is what we did because the settings in the EMC apply to everyone and you can change that but by using a OWA Policy, you can create as many as you need and apply them accordingly based on users needs.

As for the section "WebReady Document Viewing", it appears it does apply to attachments although its not very obviously in the EMC description or the Help file.

OK, I talked to Microsoft Product Support about this. This is what they said. What tabs you see when you right click the OWA (Default Web Site) and select Properties depends on what Service Pack and Update Rollup you have. Starting with SP2, Update Rollup 1, the Remote File Servers tab is gone. This feature pertains to accessing file servers and Sharepoint files only.
The other tabs, Public Computer File Access and Private Computer File Access have to do with attachments in OWA only and nothing to do with accessing files on computers other than Exchange. These features are still working and is what you should use to handle attachment processing in OWA. Lastly, if you use the Default OWA Policy which Microsoft gives you but doesn't assign automatically, this will override any settings that you make in the EMC on these tabs. I think using the Default OWA Policy is the way to go because using the EMC applies to everyone and if you want o change some settings for other users like Execs, you can always create another policy.
