Microsoft is currently rolling out a new Office 365 feature dubbed 'Unverified Sender' and designed to help users identify potential spam or phishing emails that reach their Outlook client's inbox.

"Unverified sender is a new Office 365 feature that helps end-users identify suspicious messages in their inbox," says the company on the new feature's Microsoft 365 roadmap entry.
The new indicators will be shown in the user's Outlook inbox for messages where the client couldn't verify the sender's identity using email authentication techniques.
2048-bit DKIM key sizes
Redmond is also rolling out increased DKIM key sizes to 2048-bit from the current 1024-bit size for all Office 365 customers during October, to enhance security in all environments.

"If you already have your default or custom domain DKIM enabled in Office 365, it will automatically be upgraded from 1024-bit to 2048-bit at your next DKIM configuration rotation date," says Microsoft.
