How can you include a link to a Plan in an Office Document?

Hi - I too have this issue - it often occurs with Word and I just tried PowerPoint.  The issue is:
1. Copy the RTC Plan's URL from the browser's URL bar
2. Paste URL or Insert > Add hyperlink in PowerPoint
3. Run PowerPoint as a slideshow; which 'activates' the RTC Plan hyperlink
4. Click the RTC Plan hyperlink
5. Fails with:
Error! The project XXX (CM) - action=com.ibm.team.apt.viewPlan&page=com.ibm.team.apt.web.ui.plannedItems&id=xxxxxxxxxxxxxxxxxxxxx does not exist or is not accessible with your credentials. If you have JazzAdmins privileges you can investigate the problem in the Jazz Admin Web UI.

Please try the following workaround (working for me) - "URL encode" the RTC Plan's URL. I used below tool;  scroll down a little to the section "URL Encoding Functions"  http://www.w3schools.com/tags/ref_urlencode.asp

1. Clear the field, then paste the URL from Rational
2. Click 'URL Encode' button
3. Copy the resulting/new URL into PowerPoint, Word, etc

 I found that trying to encode the URL didn't work.  It appears to really be a problem in how Windows is handling links that authenticate with Single Sign On products, which we use at our company.  I am going to investigate more with our SSO team as the issue only occurs with links to CCM but not RQM and we have SSO on for both.  The solution I found that does work requires a registry change and I would like to solve this without pushing a registry update to all our users.  The MS Knowldge article that pointed me to the solution is: https://support.microsoft.com/en-us/help/899927/you-are-redirected-to-a-logon-page-or-an-error-page-or-you-are-prompted-for-authentication-information-when-you-click-a-hyperlink-to-a-sso-web-site-in-an-office-document?cm_mc_uid=82164841234314900338982&cm_mc_sid_50200000=1491516102
