谢谢,我想我快找到问题所在了<br>
我是用OWA访问新后端服务器的邮箱出现 "503 Service Unavailable"<br>
以下是文档的解释:<br>
• 503 Service Unavailable The front-end server thinks the back-end server is down or cannot reach it. This error is generated in two situations. First, if the Information Store service on a back-end server is stopped or the user’s database is dismounted, then the back-end server returns this error. Second, the front-end server generates this error if it is unable to contact a valid back-end server. This could be because the back-end server is down for maintenance or because of network issues between the front-end and back-end servers. Use telnet.exe to verify that the front-end server can connect to the back-end servers. |
