EXCHANGE 2010 - Edge server with forefront FULL OF SPAM

Hi there.
We have recieved on Exchange 2010 EDGE server a lot of spam 200k messages in queue.
We have stoped inboud SMTP traffic on firewall to stop the attack.
Any suggestion how to empty the queue? I've heard there is a way to rename the "Exchange queue folder" but forget the procedure.
How to stop the attacker?
bostjanc

Hi There,
Use the KB below to find the Queue DB, then stop the service listed In the KB, rename the old DB and create a new one with the same name, than start the Service.

Exchange 2007 edge server with ironport

I currently have a frontend exch 2003 and backend exch 2003 server with ironport. my mx record is the ironport which then forwards into the backend server. The frontend server was only used for owa and using outlook with https connection to exchange.
With 2007 it has more functionality and the front end server is now called an edge server. Should I have mx go there then to ironport or vice versa? I'm thinking ironport to edge server to hub transport server. Is that correct? will it work?
anyone have exchange 2007 edge server with ironport? what are you doing?

well that wouldve been nice to know a little earlier. anyway I have ironport successfully sending mail to the edge server who sends it on to the hub transport server. right now the client access server is on the same as the hub but can be easily moved later. this is for very few people so its not like I need to off load anything as its a powerful dual core server. anyway now with the edge server I can test how effective it is versus the ironport. I'll let everyone know when you can ditch the ironport for msft's edge server. (Don't hold your breath).

Using Exchange 2010 Edge server as an SMTP gateway without other roles

I am looking to implement a simple SMTP gateway solution for a few applications to relay emails and hence am not looking at a full fledged Exchange deployment. As SMTP component is no longer available in Windows Server 2012, I would like to know if the Exchange
2010 Edge role can function as a simple SMTP gateway solution without having the other roles of Exchange 2010 deployed like the CAS, Hub and Mailbox ?
My requirements from this SMTP gateway solution would be the ability to append disclaimers, relay restrictions based on IP addresses and sender email addresses, and provide both authenticated and unauthenticated relay access.
Any inputs would be highly appreciated. Thanks in advance.

Hi again
I decided to test the scenario - just for fun, and it seems to work. A strange setup :-)
So you will have to prepare your schema and AD - and create an Exchange organisation.
Then you will have to assign the receive connector(s) AD permission to relay outside the organisation - by default it can only relay internal, but since your mailsystem is "outside" seen from Exchange - you'll need to do that.
Is your AD domain the same as your SMTP namespace? Because then you have to make it external relay after you have removed it from the e-mail address policy :-)

Exchange 2010 Edge server shows previous version

I have an Exchange 2010 environment with the Edge role installed on TMG and its working fine. All servers have had SP3 installed and rebooted.
I am trying to introduce my first Exchange 2013 server into the environment but the readiness check tells me not all the servers have SP3. On the Edge server it shows SP3 is installed but from all other Exchange servers it shows SP2.
Any ideas?
Thanks

For anyone else wondering. I've done this in my lab, and I didn't have to remove the old subscription, just export the file from your edge server, copy it to any server running emc internally and import it, then force a sync and the version should
update.
On edge server open exchange
     powershell and run New-EdgeSubscription -FileName
     "C:\EdgeSubscriptionInfo.xml"
Import edge file
     into new server
You
need to be assigned permissions before you can perform this procedure. To see
what permissions you need, see the "EdgeSync" entry in the
Transport
Permissions topic.
In the console tree, navigate
     to Organization Configuration >
Hub Transport.
In the result pane, click the
     Edge
     Subscriptions
     tab.
In the action pane, click
New Edge
     Subscription. On
     the New Edge Subscription page, complete the following fields:
Active
      Directory site   Click
      Browse, and then select an Active
      Directory site in the drop-down list. This field identifies the Active
      Directory site where the Hub Transport server is connecting to the Edge
      Transport server for which the Edge Subscription exists.
Subscription
      file   Click
      Browse, and then select an Edge
      Subscription file.
Automatically
      create a Send connector for this Edge Subscription   Select
      this check box to automatically create a Send connector that routes
      messages from the Exchange organization to the Internet. The Edge
      Subscription is configured as the source server for the Send connector.
      The Send connector is configured to route messages to all domains by
      using Domain Name System (DNS) MX resource records.

My macbook air cannot sync with my office microsoft exchange 2010 mail server

My macbook air cannot sync with my office microsoft exchange 2010 mail server.
It used to work perfectly, and then I lost connection and was never able to establish one. I re-istalled my e-mail account several times, no success.

I am sure all of you got your email issues sorted out by now but i was having trouble settings up exchange email on my Iphone 5S, and the problem i found was to go to settings, icloud, then log into icloud with your apple id first (before setting up the exchange email). Once i logged into my icloud account on my Phone 5S, the exchange server email starting working and synching right away.
to confirm this worked, i even deleted my email account and deleted my Icloud accounts both from my iphone was able to simulated the same exact problem (exchange server would not sync with my Iphone 5S) until i logged back into my Icloud account on my 5S.
Again once i logged into Icloud, the exchange server issues went completely away.
Just wanted to post this so anyone else having the issue could see.

Internal outlook client connectivity in exchange 2010 when coexist with exchange 2013

Hi all ,
on my side i would like to clarify few queries.
Say for instance i am coexisting exchange 2010 with exchange 2013 .Unfortunately if all of my exchange 2013 servers goes down .
Q1 .On that time will the internal outlook users having their mailboxes on exchange 2010 can be able to connect mailboxes without any issues ? In case if they face any issues what kind of issues will they be? Because why i am asking is we should have pointed
the autodiscover service to exchange 2013 during coexistence.
When an user closes and reopens the outlook after whole exchange 2013 environment failure ,outlook will first query the autodiscover service for the profile changes to get it updated on users outlook profile.In such case autodiscover service will not be
reachable and i wanted to know will that affects the internal client connectivity for outlook users having their mailboxes on exchange 2010.
Q2. Apart from outlook internal users connectivity ,what kind of exchange services(i.e owa,active sync,pop,external OA and imap) will get affected when whole exchange 2013 environment goes down during coexistence ?
I have read the below mentioned statement on this awesome blog but still i wanted to clarify with you all on my scenario.
http://blogs.technet.com/b/exchange/archive/2014/03/12/client-connectivity-in-an-exchange-2013-coexistence-environment.aspx<o:p></o:p>
Internal Outlook Connectivity
For internal Outlook clients using RPC/TCP connectivity whose mailboxes exist on Exchange 2010, they will still connect to the Exchange 2010 RPC Client Access array endpoint.
For internal Outlook clients using RPC/TCP connectivity whose mailboxes exist on Exchange 2007, they will still connect directly to the Exchange 2007 Mailbox server instance hosting the mailbox.
Please share me your suggestions and that would help me a lot .
Regards
S.Nithyanandham

Hi Winnie Liang ,
Thanks a lot for your reply.
Scenario 1 : for internal outlook connectivity
We have below settings for exchange 2010 autodiscover.
mail.domain.com - will be the namespace for internal autodiscover URI for all the exchange 2010 cas serves
We are going to have below settings for exchange 2013 autodiscover.
mail.domain.com - will be the namespace for internal autodiscover URI for all the exchange 2013 cas serves
During coexistence mail.domain.com will be pointed to exchange 2013 cas servers . I mean to say if we try to resolve the mail.domain.com it will get resolved in to the exchange 2013 cas servers.
So on such case if anything happened wrong to the new environment or else if entire environment goes down .Do we face any issues while outlook users connect to existing mailboxes in exchange 2010 ?
Because why i am asking is ,on the below mentioned article i have read all the autodiscover request will go via exchange 2013 cas servers during coexistence.That means all the existing mailboxes in exchange 2010 will also have to query exchange 2013 cas
servers for autodiscover request.During the whole exchange 2013 environemnt failure whenever the user tries to close and open outlook .Outlook will first queries the autodiscover service for any changes happened on that particular mailbox and it will try to
get it updated on user profile.
http://blogs.technet.com/b/exchange/archive/2014/03/12/client-connectivity-in-an-exchange-2013-coexistence-environment.aspx
Would it be possible to make the exchange 2010 mailbox users to query only the scp points which belongs to the exchange 2010 cas servers for autodiscover request ?
Scenario 2: For exchange services
mail.domain.com - will be the namespace for all the exchange 2010 services (i.e owa,activesync,external outlook anywhere,pop,imap)
mail.domain.com - will be the namespace for all the exchange 2013 services (i.e owa,activesync,external outlook anywhere,pop,imap)
What about the above services will it get affected during whole exchange 2013 environment failure ?
Note : We are not facing this issue , i hope everything goes well in my environment while doing coexistence i am just asking this question on my own interest?

ISA 2006 publish Exchange 2010 Outlook Anywhere with Kerberos Constrained Delegation

Hi,
I have two Exchange 2010 Sp1 CAS with Windows Network Loadbalancing. I set up an alternate Serviceaccount and mapped the http,ExchangeMDB,PRF and ExchangeAB SPNs.
Then i published the Exchange Services via ISA 2006. OWA is working using Internet -> via NTLM -> ISA(webmail.domain.com) -> via KCD -> CAS-Array(ex2010.domain.com)
I tried the same with Outlook Anywhere (RPC over HTTP) without success.
Authentication to the ISA via NTLM works fine, but i think the isa server cannot delegate the Credentials successfully to the CAS-Server.
The ISA Log looks like:
Allowed Connection ISA 24.11.2011 15:50:40
Log type: Web Proxy (Reverse)
Status: 403 Forbidden
Rule: Exchange 2010 RPC
Source: Internal (172.16.251.33)
Destination: (172.18.10.182:443)
Request: RPC_OUT_DATA
http://webmail.domain.com/rpc/rpcproxy.dll?ex2010.domain.com:6001
Filter information: Req ID: 108b89d8; Compression: client=No, server=No, compress rate=0% decompress rate=0%
Protocol: https
So i always get a 403 Forbidden from the CAS.
I the IIS logfile from the cas server i see this entry:
2011-11-24 15:51:37 172.18.10.182 RPC_OUT_DATA /rpc/rpcproxy.dll ex2010.domain.com:6001 443 - <ISA IP> MSRPC 401 1 2148074254 203
I use the same Listener for OWA and Outlook Anywhere. Authentication Methods are Basic and Integrated. I forward the request to a webfarm which exists of the two physical CAS. Internal Site Name is set to the NLB name ex2010.domain.com, SPN is set to http/ex2010.domain.com
Thanks for your support

Hi, i ran into the same Problem.
the steps above solved mine too (Creating a custom AppPool which runs under LocalSystem).
I wonder why they included only the Script: convertoabtovdir.ps1
http://social.technet.microsoft.com/Forums/en-US/Forefrontedgegeneral/thread/dc24ccd3-378a-47cc-bbbf-48236f8fe5b0
Ist this a supported configuration (changing AppPool of RPC)?

ISA 2006 publish Exchange 2010 Outlook Anywhere with KCD/NTLM and IPSEC - Problem

Hi
I have setup ISA 2006 to publish Exchange 2010 Outlook Anywhere with Kerberos Constrained Delegation and IPSEC.
The clients have an IPSEC policy pushed to them via GPO. The clients are windows 7 laptops and the ISA server is server 2003, so the IPSEC connection is IKE not AuthIP.
However, it seems that the connection will work for a while, then all of a sudden stop working with zero trace of why. I cant get the Oakley log to work and I cant see any traffic on the ISA.
I am wondering if I need to publish the CRL's externally? Currently we don't, and the Outlook Anywhere uses private certificates (as the whole point of IPSEC is to validate the internal certificate, there is no point in using
public certificates).
I have tried using the StrongCRLCheck=0 registry key in the IPsec Policy Agent on the windows 7 machine but it doesn't seem to make a difference.
Any advice would be appreciated.
Steven

Hi,
Firstly, have you received any related error messages in ISA server or on the clients' side? Besides, as you mentioned IPsec, did you have a VPN connection?
In addition,
While ISA 2006 only includes a Client Access Web Publishing Wizard for both Exchange 2003 and Exchange 2007. Which Exchange version you have chosen when publishing Exchange 2010?
Please also make sure that you have selected the
External interface for the web listener to listen on.
Besides, the link below would be helpful to you:

Exchange 2013 CAS server connection to Exchange 2010 Mailbox server

Hi Guys,
I have a quick question i am planning to upgrade my infra from Exchange 2010 to Exchange 2013 and i have come across a small question, my infra looks likes below
3 Exchange server (CAS+ HT + MBX roles) Exchange 2010
1 Exchange server MBX role For journlaing Exchange 2010
1 CAS for internet owa access Exchange 2010
Now i will be installing exchange 2013 CAS on 2 box and MBX on 3 box
will decomm the 3 exchange box which has (CAS+ HT + MBX roles) and 1 CAS which we use for owa access.
will keep the Journaling server as it is will not be decomming it as of now.
My question is is will i be able to connect to the journaling mailbox's which are hosted on exchange 2010 journaling server without actually having any 2010 cas server, will exchange 2013 cas directly help me to connect to the journal mailbox or would i need
to add CAS role on Exchange 2010 journaling server and enable outlook anywhere configure the directories with the url's to make it working.
Please suggest on the same.
BR/Deepak

Hi TheLearner,
Thank you for your question.
Exchange 2013 didn’t connect to the journal mailbox directly when we access it by outlook/OWA. The journal mailbox will connect the former Exchange 2010 CAS. Or we could migrate Journaling mailbox to Exchange 2013. Because Exchange 2010 could communicate
with Exchange 2010 by RPC, but Exchange 2013 could communicate with Exchange 2013 by HTTPS.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

Hi,
From the description, I recommend you copy the Exchange installation files to the local machine, or download a fresh copy of Exchange 2010 and then reinstall it.
Besides, please ensure that you install Exchange 2010 on 64-bit edition of Windows Server 2008 R2 Standard with SP1 or Windows Server 2008 R2 Enterprise with SP1.
If the issue persists, please refer to the following KB further troubleshooting.

IOS 4.3.1 + Exchange 2010 "was" fine with the mailbox on Ex2007 server

Hi,
i had used my iphone with ios 4.3.1 and active sync.
The mailbox was hosted on the old exchange 2007 server.
A new exchange 2010 server was running the last 4 weeks and the iphone was connection with activesync against the new exchange 2010 through local wlan and over internet.
After i moved my profile to the new server i can´t connect anymore to the new server!
Any idea what happend?

It was working fine the last weeks with my mail account sitting on exchange 2007.
Today i moved several mailboxes from exchange 2007 to 2010 SP1.
I have some domain accounts that are created new and had their mailbox created on the exchange 2010 sp1 system.
With these accounts i can connect and retrieve mails.
But with my account (moved from 2007 to 2010) i can´t.
All i get is a blank mailbox on my iphone.
I even removed the mail account from my iphone and recreated the account.
But it won´t retrieve mails.
I refresh the offline addressbook at the exchange 2010 but nothing will help.

Exchange 2010 edge transport server, degraded desktop / remote desktop

I have a 2010 edge transport server loaded on windows server 2008 R2 that after about 3 days will no longer allow RDP connections or desktop logons due to a serious performance lag / time out. A reboot clears the performance issue for about another 3 days.
I allowed an RDP connection to stay open for the 3 days and it continues to work however actions like trying to load the task manager, start button, computer or any windows not currently open takes an extremely long time. Task manager and perf mon show very
little processor and memory usage.
Tried the following to resolve:
Replaced hard drives (raid 1)
Replaced server (moved drives from one server to another chassis)
Monitoring iops, memory usage and proc transactions. Nothing shows any unusually high usage.
I tried disabled AV services, log monitoring and backup services both while the issue was happening and as preventative measure before the issue arose.

hi cna you check if by any chance you have bandwidth limitations configured. either on router or on tour switch. i had this kind of issue and it ended with bandwidth issue which was configured wrongly. you said this is happening with RDP. hows the performance
when accesing locally
did you check performance counters and event viewer.. anything there
Mark as useful or answered if my replies helped you solving your query.

Emails are Blocked from domains which are added to "BypassedSenderDomains" in Exchange 2007 Edge server

Hi,
We have an Exchange server 2007 and an Edge server 2007 is configured in the perimeter network. Most of our clients use Public email domains such as Yahoo and Gmail. Last few weeks it has been a major issue for us that most of the emails from Yahoo/Gmail
get blocked by our Edge server calming the sender IP address is in Block Lists.
As a solution I've added yahoo.com/gmail.com/aol.com/hotmail.com to "BypassedSenderDomains" hoping if emails receive from one of these domains it will bypass the connection filtering. But still some of our customers complain that their emails are
still not passing to us and blocked by our edge server. They have provided me the error message they receive.
Our clients get following error message
edgexch gave this error: Recipient not authorized, your IP has been found on a block list
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction
may be preventing delivery.
550 5.7.1 Recipient not authorized, your IP has been found on a block list
When I check the Agent logs in Edge server I found specific email had been blocked. Please check one of the log entry.
Timestamp       : 1/30/2014 1:45:15 PM
SessionId       : 08D0E865200E7CBF

SmtpResponse    : 550 5.7.1 Recipient not authorized, your IP has been found on a block list
Reason          : BlockListProvider
ReasonData      : bl.spamcop.net
This troubles me because I've added Yahoo.com to "BypassedSenderDomains" on 1/28/2014 and this email was blocked on 1/30/2014. I've checked whole Agent logs from 28th to-date and found most of the messages from white-listed domains bypassed
the content filtering but some were still getting blocked. Most of the messages from white-listed domains were blocked from "bl.spamcop.net " IP block list provider.
As a solution for the current situation I've disabled "bl.spamcop.net" from the "IP block List Providers". But the issue is, why the mails are getting blocked even the domains were white-listed. I though after white-listing emails domains,
messages will bypass the content filters if the email generates from one of the white-listed email domain.
I've also added the "Content Filter Config" for your reference.

Here is a similar issue someone with Exchange 2010 -
