Hi
I've always assumed that a restart of the Transport Service is necessary to commit changes to a receive connector, but I'd like to find out why and if it's necessary for any and all changes?
any helpful answers would be appreciated, thanks.

I've got a mixed Exchange environment with a mix of Exchange 2007 and Exchange 2010. Several servers of each version in a single AD domain with multiple AD sites in different geographical locations. This morning we started to have a very strange issue with one of our mail queues. Here is the scenario:
Site ZRH:
Exchange 2007 server: ALT06
Site DRN:
Exchange 2010 server: DRN01
Mail flow issue description:
Server ALT06 is unable to process the mail queue for message destined for site DRN to server DRN01. Mail queues for the DRN site on server ALT06. The error is 4.5.1 4.4.0 and a huge string of gobbledy gook that is not coherent at all. Telnet SMTP tests on port 25 work perfectly fine both ways. Mail from MAPI users and public folder replication get stuck in the queue. Only in this one direction ALT06 to DRN01.
I am able to send mail from DRN01 to ALT06 without a problem, although I'm not entirely sure these messages are being processed through ALT06, as there is another Exchange 2007 server in that site and its possible its failing over to that one to process the messages from DRN01. No other server in any of our sites has a problem sending mail to DRN01.
We've got the latest service pack and update rollups installed for Exchange 2007, server OS is Windows Server 2008 R2 also up to date. I ran the best practices wizard and its now showing any problems on either server. I ran the mail flow troubleshooter and it complains about ping fragmentation and BDAT command problems. However I've tried to disable this feature on both servers and that doesn't seem to be the issue.
I enabled kerberos logging and see some errors but nothing indicating a specific issue with these two servers.
I don't know what else to try and plan to open a support case with Microsoft tomorrow morning if all else fails. I've done everything I can think of to try and resolve the issue. Its strange how it had been working fine for years and now suddenly its a problem. I checked certificates and SPN entries, all that seems fine.
Anyone have any ideas of something else I can try?

We have a Exchange 2010 casarray configured with two CAS servers. The casarray is configured only using DNS.
I've noticed that connections to the casarray is 99 to 1 connecting to cas1 vs cas2.
How do I redirect and increase the connections to cas2?
Thanks

Hi,
In a recently PCI audit I was notified that the SSL version used by OWA access is accepting connections by version 2 of SSL and this is categorized as a medium risk. The recommendation is change the v2 to v3, so I ask how can I do this?
I saw the kb http://support.microsoft.com/?id=187498 and discover that I don't have SSL 3.0 subkey in the HKey_Local_Machine\System\CurrentControlSet\Control\SecurityProviders \SCHANNEL\Protocols I have only SSL 2.0 subkey.
very tks!
Have an Exchange 2010 environment with 3 Hub Transport servers. Each server HT queue is filled with what looks like some kind of NDR attack or spam attack.
451 4.4.0 Primary Target IP Address responded with: "421 4.2.1. Unable to connect."
I have tried Protocol Logging and looked at a few other things. In general, are these messages originating from Outside or Inside the network...or is it impossible to tell? I have looked at the messages carefully, and all of them have a From <>.
I have seen a few other posts talk about enabling the anti-spam agents and enable recipient filtering. The mail gateway in the DMZ is not currently setup for recipient filtering (Symantec Mail Gateway), so maybe that should be turned on? I have checked the server multiple times for outside Open Relay, but those tests come back clean. Internally, there are a few Relay Connectors for internal apps, scanners, etc. and those connectors are apparently Open Relay according to the Best practices Analyzer. I guess this is because they have the ms-Exch-smtp-accept-any-recipient permission, but the connectors are restricted with specific IP addresses.
What else can I look at?

I have a relay connector setup to send messages from anonymous to external recipients, but I have specified RemoteIPRanges for servers and applications to send email. I want to do something similar for connecting my copiers send function, but I don't want to enter the ranges, individual IPs, or networks with slash notation. Is it possible to create a Receive connector or any other object that would allow me to:
Send email from non-authenticated devices (copiers) to a specific domain (@students.domain.com) that is NOT located on our exchange environment WITHOUT having to add all the network addresses/ranges to the receive connector relay?
I only want the copiers to be able to send to internal email addresses (which it does already by default receive connector) and to students at a specific domain. No other external users.
Edit: Exchange 2010 on Server 2008 R2

Mail send through any hotmail account to my all 24 email id ...@drilbits.com gets bounced back. I had contacted to ISP and hosting company . All they says -
As IP 65.55.116.18 is not hosted with us we are unable to put whitelist request for the same. If you check whois records for the same IP it shows IP is hosted by hotmail.
Hotmail team has to contact Spamcop to whitelist their IP.

Hello everyone,
I'm new at this so I'm confused. E-mails are sitting in my out box but I'm not getting any error messages. When i trouble shoot e-mail settings, I get this error message: "Cannot send the message. 530 Authentication Required." I would appreciate any and all help.
for our application we need mails to come to the mailbox in plain text, but we don't want that the mails are sent in plain text. If I set the mailbox properties in Exchange 2010 for pop3 to plain text and I send a mail to that mailbox in html, the mail enters the mailbox in html and no conversion takes place.
The strange thing is, if I move that mailbox from our exchange2010 server to the database of the exchange 2007 server and I do the same test, without changing anything in the mailbox settings, the mail enters the mailbox in outlook as plain text as desired. Does anybody have any clues what I do wrong or where I should look on the exchange2010 server?

We are receiving the above error message from a bounce back email.
How can this error be resolved?
Just need a sanity check here.
We have Exchange 2010. Mail comes into Symantec mail gateways for virus/spam filtering. Those gateways have a SSL cert on them to allow TLS on the receive side. works perfectly, all DNS and rDNS records are set and no problems. The HT servers do not have that same certificate on the Receive Connector side and I guess it's not needed because the mail gateways are handling the TLS connection and then just passing the mail on to us.
Now, we want to setup outbound TLS on the Send Connector. Right now, it just goes out via DNS, but we want to switch it so that it goes out the mail gateways. Since the gateway will be sending the mail, does the Send Connector even need the FQDN on it and a matching SSL cert?

I have an Exchange 2010 server with SP3. It's otherwise running fine (as fine as Exchange is). We are in the midst of a migration to "hosted" Exchange (Office365).
I'm suddenly getting this error sending MAPI to Yahoo. MXTools says Yahoo's MX records are fine.
I ran th get-transport comandlet and get this message:

Hi,
We are having Exchange 2007 setup.
I have 100 external email addresses which has to be added in Exchange 2007 contacts so that it reflects in GAL of Outlook (version 2010)
How can I do that?
Please Help
Thanks
Looking to remove HT role from one of the two mailbox servers. Not sure why it is there in the first place.
I have two other HT, CA servers with a CASARRAY set up.
I have a DAG for the two mailbox servers.
The servers do not have ET roles, none are directly on the Internet, OWA is via an F5.
I see in the forum where Ex2010 and a CASARRAY there could be a problem?
Thanks for comments!
Hello
I have an odd issue with one of my clients mail delivery
Mails are being sent to two recipients.
As you can see the one is delivered and the other is marked as duplicate. This seems to be quite a regular occurrence for him, which makes me lead to believe there is an off chance the problem lies elsewhere.
Does anyone have any ideas where to look?
Regards Gilbert
