MicrosoftToday (May 1, 2025) I am seeing the upgrade notice in Yammer promising dire results if preparations are not completed and a link to message center for more info where there is a single notice updated April 8th and act by June 1st.that includes the following info:
"Check the Message center for further updates and links to documentation. We plan to release documentation for supporting the adoption of External Networks v2 before March 31st. We will also post a link to the documentation as an update to this post"
There are no further links updates or indicators of what actions admins must take to prepare so their networks are not just deleted June 1st.
Come on MS, get your act together
