Creating auto reply rule or transport rule on Exchange 2013

June 2, 2015, 1:20 pm

Hi,

I've tried to setup rules " Apply this rule after the message arrives -> have server reply using a specific message" but it won't reply. (the message is around 300 symbols, so bounce message doesn't work; also Out of office doesn't work because I want to have reply to every email which is arrived)

After few hours research I don't have any idea how to setup this. When I've setup this Outlook says me "Cannot reply to message". If I setup this rule to Exchange 2010, it work properly but on Exchange 2013 doesn't work.

Any suggestions?

Basically I need (Server Side) rule which automatically reply to all messages which arrived in my mailbox :)

Exchange 2007/2013 Coexistence Internal Relay Mail Flow to the Internet

September 9, 2013, 1:55 pm

Hello all

I have a 2007/2013 in coexistence:

2 x '07 HTs
2 x '07 CAS
1 x '07 MB

2 x '13 CAS
2 x '13 MB

On one of the '07 HTs, I've set up a receive connector for apps and printers to use for email transmission. To ensure continuity in the future, I set up a receive connector on one of the '13 CAS. Apps and printers using this receive connect will have emails delivered to in-org mailboxes but not to the Internet. Is there a configuration I'm missing?

For example, when I try to add the '13 servers to the default Send Connector to the Internet, I can only choose '13 MBs and if I do add them, I get mail bounces. What should the set up be for mail flow during coexistence? There's not much information available.

Thanks in advance.

Forwarding Shared Mailbox to DG not working as expected

We have a shared mailbox setup for our customers to send emails to. 

I need to be able to forward these messages to 2 external email addresses.

If I put one of the external emails in the 'delivery options' it works.

When I change it to a Distribution Group (with the 2 external email addresses as members), the emails are no longer received at either external email destination.

What's stopping this from working?

transport rules are skipped

Hi all,

we have a security requirement to lock down incoming and outgoing access for some of the mailboxes in our environment. as a result, we created 4 transport rules for this matter, in order of priority:

1. restrict all mails sent 'outside the organization' with no exceptions for the specified mailboxes

2. restrict all mails sent 'inside the organization' with no exceptions for the specified mailboxes

3. restrict all mails received from 'outside the organization' unless sender address pattern matches @ourdearpartner.com for the specified mailboxes

4. restrict all mails received from 'inside the organization' with no exceptions for the specified mailboxes

generally, incoming rules works fine since there can be only one sender. Problem occurs when the specified mailboxes attempt to send a single mail to 2 recipients, one inside and one outside the organization. depending on the order of rule priority, mails to either one of the recipient will go through. Note that none of the rules has the 'Stop processing more rules' option checked. The behaviour seems to be as long as one of the rules have applied, other rules are ignored. 

we have moved from domino recently and its a big security breach for us. can anyone shed some lights? TIA

mail flow not working as desired...

Hi there.

Having problem that mail flow not doing ok. Quick description of environment.

Two active directory domains (parent and child relationship)

DOMAIN.LOCAL

DOMAIN.CHILD.LOCAL

Two sites (one for DOMAIN.LOCAL and one for DOMAIN.CHILD.LOCAL)

Two Exchange servers, each and one in their own sites.

Default E-mail adress of user in site 1: John.smith@domain.com

Default E-mail address of user in site 2: Lisa.smith@domain.RS

We have 2 send connectors, one for Exchange2013 in SITE1, and the other for EXCHANGE2013 in SITE2.

This send connectors are using "unique" smart hosts. Smart host 1 is in SITE1 and Smart host 2 is in SITE2.

Ok, the wicked scenario.

User from SITE1 (John.smith@domain.com) sends mail to (John.smith@gmail.com). Mail flow goes ok, it relays thru smart host in SITE1.

Now if John.smith@domain.com send mails toJohn.smith@gmail.com and puts CC or TO also address:lisa.smith@domain.rs, then this mailflow goes "outside" toJohn.smith@gmail.com with Smart Host 2 in SITE2, which is not a desired situation.

Basically we would like to when John.smith@domain.com sends mail to:John.smith@gmail.com and lisa.smith@domain.rs, that for domain.rs exchange servers would talk to each other, but for delivering toJohn.smith@gmail.com we would like that it goes thru Smart host 1 and not 2.

I hope I have describe my situation ok and it's understandable?

with best regards

DAG group replication question

I currently have two 2013 exchange servers at our primary site in a DAG group.

DAG group replicaiton traffic is on its on subnet, traffic separate from MAPI network.

wanting to add 3rd exchange to the dag group at a remote site, connected via IPSEC VPN tunnel.

I have read that the DAG group cannot have a gateway, but my firewall people tell me they cannot route traffic to the remote site without a gateway.

so obviously I am misunderstanding something, can someone straighten me out here?

DNS question

We recently moved to Exchange 2013 from 2007, and we're in Hybrid mode right now as we can't fully divorce from 2007 yet.

I was going over our DNS records and I found that for some reason our 2013 MB server has the same external dns record/IP as the old 2007 hub transport.  I'm not sure if this is a mistake or done on purpose and I just forgot during the migration madness.

Our new 2013 CAS server has it's own external ip.

My question is, do both my 2013 CAS and 2013 MB server need IP's in external DNS?  I'm still a little fuzzy on which server sends out the mail since the roles have changed (or do they both?).  To be safe I was just going to give them both IP's so we don't get caught up in external spam problems.

Thanks,

Adding safe senders exchange 2013

Would like to add some email address to a white(safe sender) list. from what I've read is if you use theSet-ContentFilterConfig command, you overwrite the content filter configuration with a new configuration file! So how do you go about adding more than one at a time and having them all stay in the list?  Thank you for your help.

Malware detection fails to identify virus from external sender

December 8, 2015, 3:01 am

Recently one of my users I received a virus from an external sender. The virus was a VBScript macro in a Word Document. Usually the anti-malware filter would remove any suspicious attachments but in this case it left the attachment. However, when the user forwarded the email to an internal recipient the attachment was removed by the malware filtering policy. 

I can not see a reason why this would happen. I had assumed it must have been a setting in the Malware filter policy but I can not see anything which would cause this. 

Does anyone know why this might have happened and how I can stop it happening again?

DNS/SPF records

December 9, 2015, 11:24 am

I have what's probably a simple problem but it's kind of an emergency right now.

We use split DNS.  We have internally NAT ip's for the Exchange hosts.  We have an external provider for external DNS and routable IP's.

My 2013 MB server is getting rejected for a new SPF record we introduced.

v=spf1 mx a ptr include:aspmx.pardot.com ~all

The record is formed right.

I looked at the bounce message and the external service bouncing the email shows my MB server hostname, but the internal NAT ip in the text.  I'm not sure where this is coming from, I would imagine the NIC on the MB server, but obviously that is not the external reverse IP we listed in external DNS so I think this is why it's being rejected.

I was thinking I could do one of two things or both.

1. add an include for the hostname of my MB server

2. add the non-routable NAT IP to the SPF record

Not sure if i'm on the right track, or what the correct course of action should be.

Any help is greatly appreciated.

Is there a way to identify how many users have configured their account for TXT notifications? I am guessing that the information can be retrieved using powershell somehow.

Issue with mailforwarding in Exchange 2013 CU10

December 10, 2015, 1:25 am

Since we installed CU10 we have an issue with forwarding mail to another mailbox.

Here is the situation.

I edit the settings of a mailbox in the exchange Admin Center and goto Mailbox Features, Mail flow, View details and tick Enable forwarding and select the user to which the mail must be forwarded and save those settings.

When i send a test email the mailbox i just edited the mail is not forwarded.
I checked in powershell if the Mailboxproperty "ForwardingSmtpAddress" but it was empty which would explain why the message isn't forwarded. If i tick the box "Deliver message to both forwarding address and mailbox" in the Exchange Admin Center the property "DeliverToMailboxAndForward" is changed to True.

If i want to set the Mailboxproperty "ForwardingSmtpAddress" in Powershell which i already set in EAC i get the message

"WARNING: Before your forwarding settings can take effect, you need to contact your helpdesk and ask them to turn off the forwarding your administrator previously set."  in Powershell.

I order to make the function work i have to disable Forwarding in EAC en configure forwarding via Powershell.

Only then the Mailboxproperty "ForwardingSmtpAddress is filled in and message forwarding is working. The strange thing is that this way the setting is not showed in EAC.

Is this a known issue since Exchange 2013 CU10

Exchange 2013 "IP-AllowListEntry" not working

Hello,

we are using "Spamhaus ZEN" RBL for our Exchange.
There are a few IP-Adresses that I want to whitelist, this should work with "Add-IPAllowListEntry -IPAddress x.x.x.x"
The Command works successfully and returns the results with "Get-IPAllowListEntry"
Settings for IPAllowListConfig are "-Enabled True" and "-ExternalMail Enabled True"

My problem is that mails are being blocked even if they are on the whitelist.
Can someone tell me why that is happening?
I tried to restart TransportService and even whole Exchange server without success.

Hello

My company that I work in receives a lot of e-mails containing word, or excel files with a malicious macro in them. I was searching for a way, to block them but had little success.

Also i noticed, that all of them have no text written in them at all, only the malicious macro. Maybe there is a way to block attachments that have no text in them?

Disallowing local Exchange users from Email each others using different "Sender ID"

December 11, 2015, 10:22 am

Hello everyone, 
I am having hard time with this one as I have tried everything possible that I know of but to no avail. I have a customer who have 20 thousand users on Exchange 2010. There is 8 MBX servers, 4 Hub transport and 4 CAS Servers. 

The customer is complaining as some of their "Employees or Students" are using Telnet to send emails to one another using a different "Sender ID". 

This works through the default connector "Default Servername" .. 

I already told the customer to limit the servers that communicate with Exchange servers by placing IP range of the servers they have which count to hundreds of servers divided into multiple network Subnets. 

So I am looking for a solution to allow the default connector to block all users on the network from sending emails using Telnet. Is this possible at all?

Mail flow contingency for two internet breakouts.

Hi guys

Please could you advise as to the following setup configured for my Exchange server.

Our building consists of two internet breakouts, whereby the standalone 2013 Std server are configured by a public IP of the one ISP for all mail flow. We had an incident recently where this ISP line was faulty, and the second ISP line took over.

All desktop PC's and so forth were unaffected by the change of ISP for internet availability, which is not the case for the exchange services. My question is how and if possible can I configure Exchange to have the same automatic switch to the second ISP line when there's an incident like this again, having no or little disruption to the email flow and connection to Exchange from all desktops.

Regards
