SSO links/URL's doesn't work/Gets Trimmed when used from Microsoft PowerPoint and Excel / Office Products

SSO URL automatically gets updated and Target URL gets changed when you click URL from Excel or PowerPoint.

This is issue with Microsoft which creates multiple URL's when you request from Excel.

From the above URL click on Microsoft Fixit, which downloads microsoft fix.

And also as suggested in above URL you need to modify registry .

Modify the registry for Word

1. Click Start, and then click Run. In the Open box, type regedit, and then click OK.
2. In Registry Editor, browse to the following subkey:
   HKEY_CLASSES_ROOT\Word.Document.8\shell
3. In the shell key, double-click Default, and then type OpenDDE in the Value data box.
4. Right-click the Open key and click Rename. Type OpenDDE.
5. Right-click the Shell key, point to New, and then click Key.
6. Name the new subkey Open.
7. Double-click Default in the Open key, and then type Open without DDE in the Value data box.
8. Right-click the Open key, point to New, and then click Key.
9. Name the new subkey Command.
10. Double-click Default in the Command key, and then type
    "installation path\Winword.exe" /f "%1"
11. On the File menu, click Exit.

If these both doesn't work make IE as default browser. 

Thanks.
