I have 3 Exchange 2013 CU10 CAS servers load balanced by an F5. Recently I have had reports of IMAP clients not able to retrieve email. I have discovered 2 of the 3 CAS servers are not taking IMAP requests. Nothing has change recently. I tried rebooting both servers. Did not help. I enabled Outlook logging and get this:

Also have tried telnet but it will not work either for the 2 servers but works for the 1.
Our mail system seems to have become slower for a few days.
Mail is being reported as not being delivered (recipients are not getting it), or getting it 10 to 50 minutes later.
No changes have been made to our system, so not sure why this error is showing up, indicating the system is not configured correctly.
We have a period where one or two people may not get their mail for a while, maybe 20 minutes to 2 hours, and then it all starts to flow in.
Not sure where to go on this. The error above is the only error that shows in the troubleshooting assistant tests.
Thanks for some guidance.
Hi All,
I have a new install of Exchange 2010, not a migration.
I have a cas/hubt server, mailbox server and edge server
I can send/receive internal emails. I can send emails externally. I cannot receive emails from external sources.
I've gone alot of searching on this and nothing has helped so far. Both my client and Default receive connectors have Anonymous users checked under Permission Groups. I have turned off firewalls and UAC on all servers. I'm using an ASA firewall on the outside but I checked with Cisco and it is properly forwarding port 25 to my edge.
I have reinstalled the CAS/HubT server and i'm still not any further.
I can telnet port 25 to my edge server correctly. I can telnet port 25 to my cas/hubt server.
I'm stumped!!!!! HELP!

I have just upgraded to 365 Office and can no longer connect with my mail etc ... Using AT&T Yahoo and was able to connect using Outlook 2010, I do not know if I am using an Exchange Serve or POP? Have received multiple responses including :
Can not connect...
530 5.1.1 Authentication required
Using Windows 10 and my set up for Outlook used POP3, with ports of 995 and 465 with SSL.
We have an SBS server running Microsoft Exchange 2007 with all Exchange roles installed. We recently began receiving Event ID 12014 for one of the Receive Connectors:
Microsoft Exchange could not find a certificate that contains the domain name server.domain.local in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Default server with a FQDN parameter of server.domain.local. If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key.
There is a certificate installed in the personal store of the server with the SAN server.domain.local. When I run the Enable-ExchangeCertificate -Services SMTP using the thumbprint of this certificate I get the following message:
Confirm
Overwrite existing default SMTP certificate,
'thumbprint_of_mail.externaldomain.com' (expires 2/3/2017 9:14:41 AM), with
certificate 'thumbprint_of_server.domain.local' (expires 2/1/2016
1:51:17 PM)?
What I found is that there are 4 mail connecters on the server:
Windows SBS Internet Send SERVERNAME: mail.externaldomain.com
Default SERVERNAME: server.domain.local
Windows SBS Fax SharePoint Receive SERVERNAME: server.domain.local
Windows SBS Internet Receive SERVERNAME: mail.externaldomain.com
My question is, is it a common configuration to have different FQDNs in use on the connectors like this? If so, is there any way to configure Exchange to have multiple certificates so that we do not get the error anymore? I am worried that if I selected yes when running the above PowerShell command that I would begin getting Event ID 12014 for mail.externaldomain.com since the command seems to want to replace the certificate.
Any insight would be appreciated.
I am currently running Zimbra e-mail and I want to stand up and test MS Exchange 2013. I want MS Exchange 2013 to run parallel to Zimbra during testing. So my question is, how to I share my e-mail domain between Zimbra and MS Exchange 2013, with Zimbra remaining the primary mail system.
Thanks in advance for your time.
Hi to all.

How can i do this with exchange 2007
Thanks and regards.

Our company has a number of employees who are not technology users and do not have computers or AD accounts or Exchange mailboxes. Periodically HR needs to send out an email communication to their personal email address on file (i.e. Hotmail, Yahoo, Gmail, Comcast, etc.). This is an employee communication, but the concern is that those email services may see them as a mail blast since I'm sure we have a high number of email addresses on each service. The email content is the same for each employee, so there is no privacy data aside from the recipient email address.
What is the best way to send out these messages, with the goal of not having our gateways be blacklisted and not having these messages tagged as spam? Is it better to generate one-off emails with the single recipient email address on the TO line, or is it better to send fewer messages with an internal corporate address on the TO line and several hundred addresses BCC'd? Or is going through a 3rd-party like MailGun or SendGrid the best way to approach this? I believe we have a few thousand employees who will need to receive this email.
So we have built a new Exchange 2010 DAG to consolidate the 2 EX2010 DAGs that we were running previously. However once all of the old servers were off, we started getting issues on the new server (with all of the active databases) with mail queueing to"hub verison 14" and the errors were 451 4.4.0 DNS query failed. The error was:SMTPSEND.DNS.NonExistentDomain; nonexistent domain
If we restarted the Exchange Transport service, then the emails that were queued were delivered, but then any after that would queue again.
Why would this happen when the older servers were powered off? They had no route to the internet, no databases, and no client connections. Also, what makes kicking the transport service deliver the messages when they are queued?
The old servers were just powered off to make sure everything would run OK without them before uninstalling
We are at SP3UR9

We have issue with good and internal emails going to junk folder. We have Exchange Server 2010.
Before hitting the Exchange server we have MailWatch/MailScanner that marks the emails 'Clean'. There is no additional filtering that would prevent these emails to go to recipients' Inbox. Employees get these gmail and other good emails in Junk folder.
Help !
I have an exchange 2013 environment with a client access server and a mail store server. I am trying to switch our MPF's off of open relay and I am receiving the following error
Inbound authentication failed with error LogonDenied for Receive connector Client Frontend CAS. The authentication mechanism is Ntlm. The source IP address of the client who tried to authenticate to Microsoft Exchange is [10.1.1.173].
Thanks

I'm in the process of setting up a "require TLS" send connector to one of our clients sites.
What happens on my side if that connector cannot establish the TLS connection?
Do I get a bounce back message, message stays in the queue, event log entry,?
Not sure why I can't find this info, but would appreciate any insight.
Thanks!
