Plus addressing: New disable setting and on by default

Plus addressing support in Exchange Online was released in September 2020 as an opt-in feature due to its incompatibility with some preexisting addresses used by customers. New customers had the feature enabled by default and last year we announced that we would be moving ahead with the plan to turn the feature on for all customers.

That Message center post (MC276028 August ’21) generated a fair amount of feedback from customers who do not intend to allow their users to utilize plus addresses. Considering the feedback, we announced that we would implement a new setting to allow customers the ability to disable the feature ahead of the change. That setting is now ready for use, and we are giving customers 30 days to proactively opt out of the feature before we enable plus addressing by default.

Microsoft 365 compliance center: Advanced eDiscovery – Expanded support to search and export items in SharePoint and OneDrive for Business Recycle Bin (US Government clouds)

Traditionally, when a site is on hold, the files in the Recycle Bin would be stored in the Preservation Hold library. In cases when a site is not on hold, there is no way to search or export items in the Recycle Bin. The eDiscovery and SharePoint Online teams are making architectural changes that will make the Recycle Bin (both first stage and second stage Recycle Bins) in SharePoint Online and OneDrive for Business searchable and exportable by eDiscovery Managers. That means organizations can search and export items in the Recycle Bin regardless of whether a site is on hold or not.
