if you want to modify the MySite URL to point to a new URL Or MySite URL is showing wrong in office application Eg:Outlook
UAT Mysite url are created for users during the testing phase. The new production MYSITE url is not updated in AD "Web Page" attribute and outlook's "View My Site..." feature
For certain users it is pointing to an old development server.
If you basically wants to know from where the VIEW Mysite url is being picked.
This what i did to find where the details were stored
Built a test windows XP machine with SP3 and latest security updates and installed office 2007 SP2 and office communicator
Then joined the server to the domain
Downloaded the process monitor and configured the outlook settings
Opened a new email and right clicked on the user and click on "View My site" option and gathered the logs for the first time when we click on that option of “View My site”
My Site URL was https://kar-sps-iis:35000/personal/petrina
Note: I had not browsed the site nor configured it any time. Found that it modifies the following register entries when i click on view my site option in outlook
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Portal
Name PersonalSiteURL
Type: REG_SZ
Data :https://kar-sps-iis:35000/personal/petrina
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Server Links\Published\MySiteHost\My Site
Name Url
Type: REG_SZ
Data : https://kar-sps-iis:35000/personal/petrina
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Server Links\Published\MySiteHost\Profile Site
Name Url
Type: REG_SZ
Data :https://kar-sps-iis:35000/Person.aspx?user=
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Common\Portal\Link Providers\MySiteHost
Name Url
Type: REG_SZ
Data :https://kar-sps-iis:35000
Then I wanted to change my MYSITE URL to another Farm which was as at https://MySharepointSite
So the change the below register entry
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Portal
Name PersonalSiteURL
Type: REG_SZ
Data :https://kar-sps-iis:35000/personal/petrina
changed it to
https://MySharepointSite:80/sites/petrina/
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Server Links\Published\MySiteHost\My Site
Name Url
Type: REG_SZ
Data : https://kar-sps-iis:35000/personal/petrina
changed it to
https://MySharepointSite:80/sites/petrina/
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Server Links\Published\MySiteHost\Profile Site
Name Url
Type: REG_SZ
Data :https://kar-sps-iis:35000/Person.aspx?user=
changed it to
https://MySharepointSite:80/Person.aspx?user=
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Common\Portal\Link Providers\MySiteHost
Name Url
Type: REG_SZ
Data :https://kar-sps-iis:35000
changed it to
Then when I reopened outlook and then when I created a new mail and typed in the user name and right clicked on the user and clicked on view my site and it took me to
https://MySharepointSite:80/sites/petrina/
Hope this helps!!!
