Microsoft prohibits employees from using Slack, report says

Microsoft employees likely won’t be Slacking this article to their coworkers.

The company has banned or discouraged employees from using certain outside software and online services for their work due to concerns about IT security and protecting company secrets, GeekWire reported, citing an internal company list.

Popular messaging service Slack, which just went public last week, is on the list of prohibited apps, according to the report. Microsoft is instead encouraging employees to use its Microsoft Teams and Office 365 apps, saying that while the Slack’s paid Enterprise Grid version does comply with security requirements, it’s still a competitor.
