Safe Links settings for email messages Safe Links scans incoming email for known malicious hyperlinks. After the link is rewritten, it's analyzed for potentially malicious content.
After Safe Links rewrites a URL, the URL remains rewritten even if the message is manually forwarded or replied to both to internal and external recipients. Additional links that are added to the forwarded or replied-to message are not rewritten. However, in the case of automatic forwarding by Inbox rules or SMTP forwarding, the URL will not be rewritten in the message that's intended for the final recipient unless that recipient is also protected by Safe Links, or the URL had already been rewritten in a previous communication.
As long as Safe Links is enabled, URLs are still scanned prior to delivery, regardless of whether they were rewritten or not. The settings in Safe Links policies that apply to email messages are described in the following list:. Select the action for unknown potentially malicious URLs in messages : Enables or disables Safe Links scanning in email messages. The recommended value is On.

One thing we did was to run a sms package about an hour before the install that just updates a txt file on the users C drive. Only have this run if there is a user logged into the machine and after it finishes have SMS log the user off. Now you know Outlook is not open and you can have your SEP upgrade run only if no user is logged into the system. Works great for us and we use the process anytime we are doing a install that we know haveing anything open can cause a problem. It had me troubled for a while trying to pinpoint why it was happening on some machines and not others.
I at first thought it was due to an issue with email scanning optinos in SAV Thanks for the clarification. Furthermore, as of now I have not seen any additional problems with these machines This makes sense. We will probably just script the SMS package to kill outlook.
