A post by the Exchange development group tried to explain why mailboxes have SharePoint Online proxy addresses. It’s all down to the Microsoft 365 substrate, which needs the proxy addresses to ingest digital twins from SharePoint Online into Exchange Online for use by shared services like Microsoft Search. The upshot is that you can’t remove a mailbox permanently without some background processes kicking in to make sure that SharePoint is taken care of.
Planner now creates digital twins (copies) of tasks in user mailboxes in Exchange Online to make data available for eDiscovery and compliance. Storing items in the Microsoft 365 substrate is the same approach to making data available for search and compliance as taken by Teams and Yammer.
Yammer compliance records are generated by the Microsoft 365 substrate and consumed by features such as communications compliance policies and eDiscovery. In this post, we consider where Yammer compliance records are stored and what they contain and how to use PowerShell to figure out the activity levels of Yammer communities.
Now rolling out to Office 365 tenants, Teams meeting organizers can review the attendance data for meetings and webinars in a new dashboard. The same data can be downloaded to a CSV file for analysis. Teams stores the attendance report data in the Exchange Online mailbox of the meeting organizer. It’s a good example of the Microsoft 365 substrate in use.
The Microsoft 365 substrate now captures Teams app card data in compliance records to make the data available for eDiscovery, content searches, holds, and retention. The compliance records are stored in user and group mailboxes. Audit records for card interactions are also logged in the Office 365 audit log. Using compliance records means that some app data context is lost, but at least you can find the information.
Project Moca is a new Office 365 personal productivity app which doesn’t have a mobile app. It’s hard to be productive if you can’t be when mobile. Which is why To Do allows people to capture thoughts. A workaround of sorts is available through To Do tasks. Whether this is enough for you to switch to Moca is debatable.
