We are using the SMTP email action for our alerts and within the SMTP action body we are using : ${Problem_Detail_List_All} When we receive an email, the link has %253A instead of %257C which is the URL excape character or | (pipe)  
The link that does not work has "%253ANumber+of+Connected+Collectors" where as the link that does work has "%257CNumber+of+Connected+Collectors" How to correct the SMTP metric link from the ${Problem_Detail_List_All} variable.
Fixed in HOTFIX 10.5.2 HF37. Please contact CA Support to obtain HOTFIX.
