Microsoft announced a new variant of its Office 365 service called 'Office 365 Germany' for organizations operating under substantial regulations in Germany, the EU, and the European Free Trade Association (EFTA).

This new subscription offering has been specifically designed to store customer data at rest within the country while also meeting the stringent access and control requirements demanded by German law and EU regulations.

"Office 365 Germany provides innovative, cloud-based productivity tools that enable our customers to grow their businesses and meet their strict compliance restrictions like data residency in Germany. We are providing our customers a unique, differentiated option in how their data is handled and where it is stored, helping them fuel their digital transformation," Sabine Bendiek, of Microsoft Germany said.

Microsoft is also stepping up its efforts to protect Office 365 users with the addition of two new capabilities to optional Advanced Threat Protection (ATA) subscription—"URL Detonation" and "Dynamic Delivery"—improving the security while keeping people productive.

ATA launched in April of 2016, offer powerful safeguards like Safe Links, which provides time-of-click protection to help prevent users from opening or accessing malicious links, and Safe Attachments, which protects users from opening malicious email attachments.

"URL Detonation" general available today helps prevent users from being compromised by files linked to malicious URLs.

When a user receives an email, this new capability also checks the URL reputation that the ATA already does analyze for malicious behavior. During the scan, when a link is clicked, a message "This link is being scanned" is displayed, and if the link happens to be malicious, "a pop-window after the scan opens notifies and prevent user from opening it."

To appropriately focus on remediation efforts for impacted users while not disrupting the work of unaffected users, IT admins can implement a URL trach SafeLink policy that track user clicks, and prevent users bypassing the warning and click through to blocked pages.

Clicking the placeholder attachment, shows a message of scan in progress, while "harmless attachment seamlessly re-attaches to email," "malicious ones are filtered out by the Office 365 ATA."
