Change link in sidebar on Sharepoint site

are you referring to your SharePoint 365 subscription or a local SharePoint server on premises?

generally speaking, you can find the section and it’s code from your site’s master page. see below the related official how-to guide for SP365. you may also simply check the source code of you SharePoint server’s main page, and search for the given phone number to locate that section.

This is sharepoint 2013.  I know how to change the main default page using expression, but this is a right hand side bar on an announcement page.  I cannot even find where the sidebar is stored in sharepoint to make the change.  if I could find it, I could change it.  Any ideas where this would be store at?

do you mind to share the SharePoint server's the URL if it is public accessible? or, can you upload the source code (HTML file) of the main page for review?

I need to change the link on the right rail that says, "Get Help Now >"

if I downloaded it to Expression, change the link, and uploaded would that work, or cause problems since it's not a master page it an announcement page.  I cannot find where it is located in web parts, columns, or anywhere else.

I have no idea if on this announcements page if it's a right rail, a web part, just a column, or a combination.  I have searched through every folder in the site contents and cannot find this box.  I have searched all the images and can't even find were it's pulling in the orange guy.  I didn't create this site and can't find anything.  Some of what I do find is not stored in the proper folder.

Correction, I just found the png it's using.  the path is ..._catalogs/masterpage/GCI/images/

Thank you.

you are welcome. glad to help.
