Microsoft to retire Microsoft 365 Companion apps in December
Summary
Microsoft is retiring its Microsoft 365 Companion apps, including Calendar, People, and Files, on December 16th. Administrators are advised to remove these applications from managed devices before the retirement date.
IFF Assessment
The retirement of companion apps may impact user workflows and potentially introduce a period of instability or require users to find alternative solutions, which could indirectly affect security practices.
Defender Context
While this is not a direct security vulnerability, the retirement of core functionality within Microsoft 365 requires administrators to plan and execute the removal of these apps. Defenders should monitor for any user-reported issues or potential disruptions that could arise during this transition, and ensure that alternative solutions are in place and secure.
