Hi everybody,
My company is encountering issues with Exchange 2010.
No one in the company is able to send mails today (we can receive). Outlook and OutlookWebApp seem to work correctly : when we send (or try to send) mails, we have no error message.
It would be too complicated to describe our infrastructure (one server work as Hub and ClientAccess and another one work as Mailbox server). I used Tracking Log Explorer in Exchange Management Console to verify if there is an error and I can see all messages I sent and I received until yesterday but I have no trace of messages I tried to send this morning.
Where can I search to identify the problem ?
I know I give a few information but I'm looking for ideas to try to solve my problem.
Thanks in advance for your help.
Have a nice day.
