If Microsoft Office Word or Excel hyperlinks are slow to open, under usual circumstances or when they point to Microsoft AD FS Server, then try these suggestions:

Active Directory Federation Service (AD FS) enables single sign-on functionality which offers customers a streamlined user experience while accessing the web-based applications of an organization, However, at times, when you try to access such sites through hyperlinks in Microsoft Office applications like Word or Excel the sites take a minimum of 60 seconds to open. This issue mainly arises because of the following 2 reasons. First, ADFS is not equipped to handle a HEAD request that it receives from either Word or Excel applications. Second, although AD FS attempts to respond by returning an error message, the AD FS protocol rejects it since the HEAD response can’t contain a request body. To fix it try the following:

Open the Windows Registry Editor. For this, press Win+R in combination to bring up the ‘Run’ dialog box. Type ‘regedit’ in the empty field of the box and press ‘Enter’. When the Registry Editor opens, navigate to the following path address –

Create a new registry key – DWORD – ReplaceHLinkHEADRequestWithGET.

Double-click the entry and change its value from default ‘0’ to ‘1’. When done close the Registry Editor and Exit. Restart your PC. Your Problem should be fixed and Office apps like Excel, Word should not take long to open AD FS sites.
