163的邮箱密码连续错误几次，一般的情况要3个小时才能再登录上。有的邮箱是需要更换个IP就可以，建议重启电脑进行登陆。
更换电脑IP方法：
1、点击桌面的网上邻居，反键，然后点击本地连接;
/iknow-pic.cdn.bcebos.com/0df3d7ca7bcb0a46fe6692c56063f6246a60af81"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/0df3d7ca7bcb0a46fe6692c56063f6246a60af81?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/0df3d7ca7bcb0a46fe6692c56063f6246a60af81"/>
2、本地连接同样反键属性;
/iknow-pic.cdn.bcebos.com/fc1f4134970a304e5ab8b906dac8a786c8175cb7"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/fc1f4134970a304e5ab8b906dac8a786c8175cb7?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/fc1f4134970a304e5ab8b906dac8a786c8175cb7"/>
3、常规这里，把自动ip修改下面的使用下面的ip地址;
/iknow-pic.cdn.bcebos.com/9c16fdfaaf51f3deee76a0989feef01f3b297901"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/9c16fdfaaf51f3deee76a0989feef01f3b297901?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/9c16fdfaaf51f3deee76a0989feef01f3b297901"/>
4、修改的地址根据你实际的网管，DNS来进行设置修改，第一个是ip，最后一个数字是你的本地电脑的ip地址;
/iknow-pic.cdn.bcebos.com/c2fdfc039245d68843c3ab58afc27d1ed31b240c"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/c2fdfc039245d68843c3ab58afc27d1ed31b240c?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/c2fdfc039245d68843c3ab58afc27d1ed31b240c"/>
5、然后点击确认，电脑会断线一下，再自动连接，就可以了。
