我的错误是：
May 19 11:14:05 data-2 postfix/smtp[23560]: 359DA41830: to=<[email protected]>, relay=smtp.office365.com[40.101.50.194]:587, delay=1616, delays=1498/0.02/118/0, dsn=4.7.3, status=deferred (SASL authentication failed; server smtp.office365.com[40.101.50.194] said: 535 5.7.3 Authentication unsuccessful [HE1PR0902CA0020.eurprd09.prod.outlook.com])
我该如何避免这种情况？如何将“Exchange 用户”添加到“权限组”？
谢谢
