security issue for corporations

[Dirk Van Vulpen]

Hi My company is blocking planner (and Teams) due to security issues that need to be worked out. Is this a known and issue being worked on? Erik

Can you elaborate more on that please? It sounds like they are blocking Office 365 Groups, which would subsequently block Planner and Teams.
There are no security "issues", more so probably a lack of understanding by the IT team on how to actual secure their Office 365 environment adequately using the built-in functionality.
