How to Fix Outlook 2016 not previewing Excel files

 

1.          Type regedit and Press Enter. Click Yes if a User Account Control confirmation message appears.

 

2.          Navigate to the path below:

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Microsoft\Windows\CurrentVersion\PreviewHandlers

 

Note:

If you have installed a 32 Bit version of Microsoft Office and you have a 64 Bit Windows installed, then follow this path:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\PreviewHandlers

 

If you have a 32 Bit version of Microsoft Office installed on a 64 Bit Windows or a 64 Bit version of Microsoft Office installed on a 64 Bit Windows, then follow this path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PreviewHandlers

 

3.          Once you have selected (Highlighted) PreviewHandlers in the left pane, there will be number of registry strings in the left pane. But there are only 4 of them that concern us.

            On the right you will be able to see three columns; NameType and Data. In the Name column, search for the four strings by the following names and make sure the corresponding value in Data is exactly          the same as written below.

          Name                                                                                                                Data

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

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

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

            {00020827-0000-0000-C000-000000000046}                        Microsoft Excel previewer

 

If the value differs in any one of the strings, then Double Click the incorrect string to modify it.

4.          In the text below Value DataErase the old value and Type the value according to the table above.        Then Click OK.

            If more than one string has the incorrect value then you will have to correct them all.

If the registry strings are missing entirely, then Right Click in the left pane and Click New and then Click String Value. Then name the registry string according to the table above.

5.          After that, Double Click the registry string to modify it and Type in the Value Data according to the       table below. Repeat the process for the other 3 strings too.

 

6.          Now Restart your computer and check if the issue resolved
