Using New Outlook on Windows for personal email, calendar, and contact management
Hello @Family Nutland
I understand your concern, especially since the advertisement led to a site your security software flagged as unsafe.
First, a clarification: advertisements in the free version of Outlook are an intentional part of the product. Free personal accounts can see ads alongside messages in the inbox, identified with an Ad label. A Microsoft 365 subscription provides an ad-free Outlook experience.
However, seeing an advertisement does not mean Microsoft is guaranteeing that the advertiser or destination website is trustworthy. If Norton blocked the destination, do not bypass the warning or revisit the site. If you believe the advertisement itself is deceptive or unsafe, also report it through Outlook using Help → Feedback, including a screenshot and the advertiser/domain if possible.
Since you already have Microsoft 365, there's another thing to check. If you're a subscriber but still see ads, make sure the Outlook.com address linked to your Microsoft 365 subscription is added to the Outlook app and that the subscription is still active.
Also, check which account is currently configured as the primary account in new Outlook:
File → Account info → Accounts → Your accounts
Find the account associated with your Microsoft 365 subscription, select Manage, and check whether it is the primary account. Microsoft now supports changing the primary account in new Outlook.
Also, you don't normally need to forward all your other email addresses into one mailbox. Current New Outlook supports multiple accounts, including Microsoft accounts, Microsoft 365 work/school accounts, Gmail, Yahoo, iCloud, and other IMAP accounts. You can add another account under Accounts → Your accounts → Add Account.
Before abandoning new Outlook, first verify that the Microsoft 365 subscription account is added to the app and recognized correctly. If it is, but you're still receiving Microsoft-served ads, that would be useful information to include in your feedback to Microsoft.
