This week’s Microsoft 365 News
Exchange and Samesite Updates
This update rolls out to Chrome on February 4th. Chrome (and therefore, Edge) changes the way that cookies are handled, which breaks OWA. Office 365 has been updated to address this, so no action is currently necessary.
Exchange 2016 and 2019 will get updates in the March CUs. But there's no news on Exchange 2013 and 2010 yet. In the meantime, there’s a setting you can deploy if you manage Chrome settings via Group Policy on the Exchange Blog.
Microsoft Teams limits and specifications have been published
This is a useful resource if you need to know the specifics of how many members can be in a team, how many teams people can be a member of, how many private channels per team, and so on. This is a useful update and similar to the service descriptions for other Office 365 services.
Web Content Filtering for Defender ATP is in public preview
This is a new feature that enables you to enforce a cloud proxy service for Defender ATP users. You need a separate subscription to use this – you can get a free 60-day trial to play with it from Cyren. It’s fairly basic at this time – but allows you to block content, such as adult content, from all managed devices.
New on the Roadmap
Teams Private Channels gets Legal Hold
This was missing at Private Channels launch, so it’s a welcome addition – if you’re already holding channel content, there should be no action needed.
Outlook for iOS and Android is getting the new Fluent design
This is going to be limited and to begin with, the new icons will be featured in the application itself, rather than a completely new design. Expect it to drop in February (so… any time from tomorrow!)
In Outlook, you’ll be able to reply to a comment in Office apps, directly from Outlook
This is rolling out now – usually, you’ll just see “@someone” mentioned you – click here to view the document”. Now you’ll get context around this and the ability to reply directly.
Security Default – covered on Practical 365 last month, hits GA
This replaces the “forever in preview” Baseline Protection policies in Conditional Access
