Emergency alert: Microsoft acknowledges Outlook slow startup issue, reveals temporary solution in advance

Microsoft officially confirmed on June 21 that there is a serious vulnerability when Outlook is started, which may cause the application to freeze on the opening page. The company has released a solution to this problem
