for M365 admins

The news this week is full of Anthropic's Claud. It is scentient? Will the IPO be record breaking? Is it destroying future mathematicians? Big heady questions. No one has the answers. It our level I'm not sure that it's worth discussing. We need to focus on Microsoft 365 and what we need to do this week.
 
Last week I asked whether you had reviewed the status of oAuth apps prior to the Skykick/Connectwise problem. Thank you for restoring my faith in MSPs. 74% of you responded that you had reviewed them prior to this incident. This is some really good news. It's a modern problem that requires a new set of routines. I'm glad to see that it's been embedded in practice. 
 
In the Newsletter this week
 
There are some new things to understand: SharePoint hero links, Teams meeting archives, the new OneDrive layout. There are important things to do this week: Secure Teams meetings by default and update your retention policies. These all represent change. It's the contsant in the world of the IT Admin.
 
4 things to know: Create one SharePoint sharing link to rule them all. Meetings Archives are optional but probably useful. Powerpoint Copilot will ask you questions about your presentation. How does Copilot memory work?
 
From Third Tier and B² MSP Advisors:
ThirdTier: Article 6: Having the business conversation to turn discovery into money.
B²: Discount for newsletter readers! $300 0ff. October 27th a small group of MSP start working to make their MSP more valuable

Are clients allowing you to restrict AI app usage?

 
I hope that you enjoy this week's newsletter and tell everyone to subscribe.

thanks, Amy

OneDrive is making it easier to find and work with files across Microsoft 365. We're refreshing the filtering experience across OneDrive Web, updating existing filters in views like Home, Shared, People, Meetings, and Favorites to support multiple filters at once, and bringing those same filtering capabilities to folder-based experiences such as My files and shared folders. Users can also filter content by file type using both filter pills and the filter pane.
