Outlook Cannot Preview Excel Files

Problem:  Outlook 2016 cannot preview Excel file attachments.  Additional symptoms include unable to copy or save Excel attachments.

Error:  This file cannot be previewed because there is no previewer installed for it.

Reason:  Microsoft plans to correct issue in future program updates.

Solution:  Change registry setting to correct this problem:

Registry Change:

String: {21E17C2F-AD3A-4b89-841F-09CFE02D16B7}
Value: Microsoft Visio previewer

String: {65235197-874B-4A07-BDC5-E65EA825B718}
Value: Microsoft PowerPoint previewer

String: {84F66100-FF7C-4fb4-B0C0-02CD7FB668FE}
Value: Microsoft Word previewer

String: {00020827-0000-0000-C000-000000000046}
Value: Microsoft Excel Previewer <\code>
Additional Note:

This seems to be a problem with all the Outlook 2016 installs.  Consider creating a group policy to push this change to all computers with the software installed.

 That's it!
