Q:  Can I view PDF files and HTM files in the browser?  Can I integrate CRM 2011 with Sharepoint Online?

A: No and No.

Permissive Browser File Handling Needed

Sharepoint Online in O365 beta does not have the option to set Browser File Handling = Permissive.

Sharepoint Online in O365 beta does not have the option to allow additional file extensions.

The following scenerios don't work as a result of these:

Document libraries:

1)  Can't open PDF files in browser.  Must download, save then open with pdf reader locally.

2)  Can't display HTM, HTML files in browser.

3) might affect flash objects

CRM:

1)  Can't integrate MS CRM 2011 Online with Sharepoint Online.  This requires permissive and .htc file extension be added to allowed extensions.

You can open a Support Request from the Admin page or call phone support.

You can get the suppport number by following instructions here:

Then state the problem:  I need to view PDF files and HTM files in the browser.

or

I need to enable sharepoint online integration with CRM.

These require 2 server side changes which are not available presently in SP Online Admin Center:

1) Browser File Handling set to  Permissive.

2) .htc file extension added to allowed extensions.

Here is a link to a couple pages of threads that involve this issue (there are more than these):
