A mass email sent by a Microsoft employee appears to have gotten around a block on words like “Palestine” and “Gaza” that the company put in place earlier this week.

Following multiple employee-led protests against the company’s contracts with the Israeli military, Microsoft workers discovered that any emails they send containing the word “Palestine” inexplicably disappear.

Microsoft employees have realised that emails sent within or from the company account that contain words like “Gaza” and “Palestine” have been blocked after a series of proteststors interrupted the company’s flagship Build event on Tuesday.
