Microsoft Exchange Server on prem gets a little harder to use
It’s the end of the road for yet another facet of Exchange Server, Microsoft’s on-premises email and calendar system. The stripped-down version of its web client, Outlook Web App (OWA) Light, is being retired, forcing those Exchange Server users still using it to adopt the standard Outlook Web App instead.
“OWA Light was created for a much earlier era of the web, when browser support, bandwidth, and accessibility technologies were very different from today. Going forward, we want to invest in a modern Outlook on the web experience that provides the cross-browser, accessible, and security-focused experience,” said Microsoft.
Those enterprises still operating in a resource-constrained environment are out of luck, then.
The change will be effected in an upcoming Exchange Server update expected in August. The move should come as no surprise: Microsoft had already deprecated the light version of Outlook in August 2024. Microsoft said that sysadmins should spend the next couple of months preparing for the change by identifying any staff still using OWA Light.
This is just the latest alteration that Microsoft has made to its Exchange ecosystem, which some holdouts still use instead of the SaaS-based Microsoft 365 service. However, even on-premises customers must now pay a subscription fee to use Exchange Server.
One of the advantages of SaaS offerings is that customers don’t have to deal with patching, an advantage brought home to on-premises customers in May when a zero-day exploit struck Exchange Server.

Mistral joins rush to build physical AI
French AI company Mistral claims its latest AI model offers a more efficient way to train and operate robots.
The model, Robostral Navigate, can guide a robot through plain language instructions, using a single RGB camera to find its way. Mistral said that this was a radical departure from most other models, which rely on depth sensors, LiDAR or several cameras working together.
Robostral Navigate has achieved a score of 76.6% on the R2R-CE (Room-to-Room in Continuous Environments) benchmark for robots following instructions. This beats the best system using depth sensors or multiple cameras by 4.5 percentage-points, despite the Robostral Navigate using neither of these aids, and puts it 9.7 percentage-points ahead of the next-best single-camera robot.
Mistral said it had designed the model to autonomously navigate complex environments including offices, residential and commercial buildings, and outdoor settings. A key feature of the new model is that it is easier to train: Mistral said the number of training tokens is reduced significantly compared to other models, reducing training runs from months to days.
Robotics is an area ripe for AI research: The World Economic Forum at Davos in February heard how AI-driven robotics could drive advances in productivity.
Other AI model developers are ahead of the game: Nvidia announced robotic AI efforts in August 2025.

Apple will buy more US-made components from Broadcom
Apple has agreed to buy up to $30 billion-worth of additional chips and other wireless components from Broadcom over the next few years.
The new agreement could lead to Broadcom making up to 15 billion more chips in the US, and enable it to modernize its manufacturing facilities in Fort Collins, Colorado, where it will produce radio frequency components including thin-film bulk acoustic resonator (FBAR) filters and advanced wireless connectivity technologies, Apple said.
The deal is part of Apple’s effort to create an end-to-end supply chain in the US. It has already been exploring options that could wean it off Chinese-made chips. Last year it launched its American Manufacturing Program (AMP) to accelerate manufacturing in the US, committing to “invest $600 billion in the US economy over four years” in support of local manufacturing and jobs.
US companies have been keen to source chips manufactured in the US to eliminate supply-chain uncertainty in the face of President Trump’s ever-changing tariff policies.
“We’re grateful to the president and his administration for supporting important projects like this one,” Apple CEO Tim Cook said in a news release, without specifying the nature of the Trump administration’s support for such deals.
He said the components Broadcom makes in Fort Collins were essential to Apple’s products.
