Error – “Updating hybrid configuration failed with error ‘Subtask Configure execution failed: Configure Mail Flow”
If you are using wildcard certificate in your default website in IIS ,*.domain.com is not a valid FQDN for a send connector in Exchange sp2 . There two ways to solve this issue :
1. Install exchange SP2 rollup 1 – http://www.microsoft.com/download/en/details.aspx?id=28809
2.If you dont want to install the update, i found a workaround in this a grate article
