Microsoft has banned the use of the free version of Slack for over 100,000 employees. GeekWire states that Microsoft has a list of prohibited apps and services, and that even Amazon Web Services (AWS) and Google Docs are "not recommended" for in-house use. However, the slack ban is not primarily determined by the competing Microsoft team product. Microsoft is reportedly concerned about the security issues of Slack Free and Slack Plus. An internal entry describes the situation:
"The Slack Free, Slack Standard, and Slack Plus versions do not provide the necessary controls to properly protect Microsoft Intellectual Property (IP). Existing users of these solutions should migrate the chat history and files related to Microsoft Business to Microsoft Teams. Microsoft Teams offers the same features and built-in Office 365 apps, as well as call and meeting features. Learn about the additional features that teams can provide to your workgroup. The Slack Enterprise Grid version complies with Microsoft security requirements. However, we recommend using Microsoft teams instead of competing software.
This means that employees can use Slack Enterprise Grid However, given the associated costs, it is by far more likely that most groups in Microsoft use the preferred Microsoft Teams option. Using AWS and Google Docs is reportedly requiring "business eligibility" for employee use, and even Microsoft's own GitHub is not advised when it comes to "highly confidential information, specifications, or codes."
Microsoft has also banned grammar in the company. This is an app for writing and reviewing the grammar that can monitor every keystroke. "The Grammarly Office add-in and browser extensions should not be used on the Microsoft network because they can access information protected management (IRM) -protected content in emails and documents," the leaked list said.
Microsoft's Forbidden List For security-related matters, this makes sense, but staff must continue to use these competing services to promote their own products and understand the broader market. This is an essential part of any business permission to access services such as AWS or Google Docs.
Microsoft aggressively competes with Slack, but the messaging service has recently launched apps and integrations for Slack and Office 365 to fill this gap. Microsoft launched its free-of-charge version of teams earlier this year to keep up with Slack just weeks after the company unveiled creative new features for conference calls to its Slack competitor.
