I have a Exchange 2013 server that was working great for a at least a week, then one day I found I couldn't SEND any e-mails out of the system. Outlook shows them as sent, OWA shows all of my e-mails in the drafts folder.
I can receive mail just fine and if I SMTP relay (authenticated) those e-mails send (Basically if my account was POP/SMTP style). But normal e-mails using Outlook or OWA do not send and I can't even send to myself! When I perform message tracking, the e-mails show as sent.I'm totally lost and nothing seems to make sense! I dont have Ex2013 but to me it's sounds more like a DNS issue.The domain you are trying to send hard code that in a HOST file on your exchange server and then try to send.For example: if you are trying to send email to gmail.com. Then add the gmail.com domain in your host file that sits on exchange server.Second you can try, is on your exchange server NIC change the DNS1 to google DNS.
See if this helps. I think you might need to add google DNS to your DNS Forwarder too.Try these see if anyone helps!Cheers,IT. It's a crude as I didn't have a lot of time, but here are my settings. Once I put them in place, mail worked as expected.
If you have a lot of mail stuck in the drafts, it may stay stuck.I have 18 drafts that won't go away, but all new mail sends and receives just fine. Since I'm the only one that tested, I don't care that I see these 'old' drafts. No problem, glad to help a fellow IT person in the trenches!My scopes are all 0.0.0.0-255.255.255.255 for all connectors. The default internet receive one (port 25) I will be changing to my hosted spam filter once we get one, but if you don't have one, you really need to keep it completely wide open, or you will not receive e-mail from many people.It also appears Exchange 2013 really doesn't want you to authenticate on port 25.
So for the random people or applications that use SMTP, use port 587. With the connectors I gave you, I allow TLS or no TLS for the 587 auth, so it will be compatible with any application that can support changing to port 587.Just being curious, did your drafts all your old stuck drafts disappear?
Server is Exchange 2007 2013 (we upgraded in the last few weeks), Client is Outlook 2013 on Windows 7 Pro. Update: The user's description of the issue was 'all new mail', but I noticed that it is actually only mail from mailing lists and Gmail accounts that is being moved. Mail from internal addresses and non-Gmail accounts is staying in the inbox.
