My email system is a hosted exchange. How can I therefore setup Alerts within Sharepoint

Hi Sunny, Thank you for posting in the Microsoft TechNet forum! From your post, my understanding on this issue is: you want to allow SharePoint on-premise to use hosted Exchange, like Exchange Online, to send alerts. If I'm off base, please feel free to let me know. I believe you don’t need to use smpt.mail.microsoftonline.com if you are sending to BPOS user mailboxes, as you are not doing a relay. On-Premise->Cloud SharePoint (On-Premise) ->SMTP Server -> mail.global.frontbridge.com ->BPOS For more information about configuring SharePoint outgoing e-mail with Exchange online, please refer to the following articles: http://social.technet.microsoft.com/Forums/en/onlineservicesexchange/thread/e83160af-bd1f-4691-836a-e967218baf62 I hope the information above can address your concerns. If anything is unclear, please feel free to let us know. Rock WangRock Wang MSFT

I used the service of SMTP.com which provides Authentication free SMTP. Use it in the Outgoing mail setup and it worked like a charm. Thanks
