Microsoft bans 38 file extensions in Outlook for Web
Microsoft has blocked 38 new types of file extensions on its Outlook for the web email platform in a bid to protect email users from what it deems ”at-risk” file attachments that were usually sent with malicious scripts or executables.
“The list, which previously included 104 file extensions, will be expanded ”soon” with 38 new entries. These new entries are file types that are regularly used to deliver malware to Outlook inboxes.
