How to Block spam,malware in exchange server 2013

How to block spam,junk mails inexchange server 2013 with out blocking normal mail. when i tried enable antispam on my sonicwall some important mails also removed. how to rectify these issues

Hi ,
To get it corrected , please contact sonicwall vendor to reduce the aggressive blocking in sonicwall.
If you are not interested in third party solutions please use the EDGE SERVER as your smarthost and on that EDGE server you can enable Anti-Spam features to block the forged connections and fake mails.

How can I clone a completed Exchange Server 2013 in a Lab Enviroment?

I was having great time with my Exchange Server 2013 until I tried to clone it to avoid fresh installation of another Exchange 2013 server. Steps taken
(1)Clone the Exchange1 and turn it off
(2) Brought the Clone Exchange2, renamed it, change the IP configurations,
(3) Re-ran the ADprep/Doamin prep
(4) Checked the ASDIedit to verify the Schema/configuration in AD
(5) Restarted I and was able to logon to the Exchange2
(6) Brought up the Exchange1, but unable to logon because the name was no longer in AD database
What I did to fix this:
(7) Rejoin the Exchange1 to the domain - and was able to logon
(8) Unable to access ECP or OWA of any of the two servers.
(9) Errors received - Fix the configuration file of the application
My Question - How to I fix the configuration file as suggested (via powershell or GUI or ASDIedit.msc)?

Unless you are cloning an entire environment, and then bringing it up in a seperate isolated environment, it is not supported to simply clone an Exchange Server, and then bring it online in an existing environment and rename it to save on setup and configuration
time.
You can script the setup and configuration of Exchange through Powershell, either with scripts or with another product controlling it - something like
System Center Orchastrator.
From the script side of things there are many available on peoples blogs. Check
here.
Edit: and to be clear, there is no need to re-run any prep tasks against Active Directory when installing a new Exchange Server, unless you are installing into a new domain as part of your Forest.

Blocking Spam Emails by subject name in Exchange Server 2013

Hello Guys,
I need to know how to block spams by subject from Exchange Server 2013's Anti-spam/message filter.
In general, I'm using Exchange's anti-spam agents and configured spam blocking by domain name.. but I need to filter unnecessary emails by subject name also.
So, if you know how to resolve this issue, please post here the real solution..
Thanks a lot,

Hi GMG,
Thank you for your question.
We could install Exchange 2013 edge server, then we could create item which block spam base on subject name in “Protection”, we could refer to the following link:
https://technet.microsoft.com/en-us/library/bb124701%28v=exchg.150%29.aspx
There is a another method, we could use transport rule to filter spam by subject name by the following link:
https://technet.microsoft.com/en-us/library/dd351127(v=exchg.150).aspx
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

How to upgrade Exchange Server 2013 CU5 on my site?

My site have four Exchange servers . The four Exchange Servers are installed mailbox and cas roles. The
Dag achieved by the four servers. Please help me to upgrade exchange server 2013 cu5 on the four servers. how to do? Thanks.
北京老马

Hi Martin
Find the below information.
Upgrade Sequence for each Role:
==========================
You should upgrade your Exchange 2013 server roles in the following order:
Client Access
Mailbox
Edge
For DAG members
Upgrade only passive servers in the first phase.
Before you apply the service pack to a DAG member, move all active mailbox database copies off the server to be upgraded and configure the server to be blocked from activation.
Place server in DAG maintenance mode before applying the service pack to any DAG member,
Stop any scheduled tasks or other processes running on the DAG member or within that DAG that could adversely affect the DAG member being upgraded or the upgrade process
Good Luck !!

How to block spam email sender on iMac ?

How to block spam email sender on iMac ?

You can setup a Junk mail filter in Mail preferences, it will still enter your mailbox but be under a Junk folder. You can then check and if required delete the mail.
In this web page note the option of applying the filter via webmail on an IMAP server such as iCloud.
http://itservices.stanford.edu/service/emailcalendar/email/spam/filters/osx
Another option is a commercial filter for Mail, this one but I know nothing about this software, a google search will probably find others.

How can i get newly added contacts for a Mailbox User in Exchange Server 2013

Hi all,
I need to synchronize contacts in Exchange Server and Sugar CRM Application, for that
i need to get newly added contacts for a User in Exchange Server 2013 by using EWS Managed API.
I know how get the list of all contacts for a particular user , but in the list how i can find
new contacts ?

Hi Dora,
that's the fun thing:
You add your own property (and it'll be invisible to outlook users, not to worry).
Extended Properties allow you to define custom property on Exchange Items. And it has a
method for setting those too.
Here's a short post doing a very simple intro on using Extended Properties.
Glen's Exchange Blog is a generally useful resource when working with EWS, I'm confident you'll be able to find lots of tips there as well.
Cheers,
Fred

Dear all,
We have an server that runs Microsoft exchange server 2007 with the following specification:
4 servers: Hub&CAS1 & Hub&CAS2 & Mailbox1 & Mailbox2
Operating System : Microsoft Windows Server 2003 R2 Enterprise x64
6 mailbox databases
1500 Mailboxes
We need to upgrade our exchange server from 2007 to 2013 to fulfill the following requirment:
I want to upgrade the exchange server 2007 to exchange server 2013 and implement the following details:
1500 mailboxes
10GB or 15GB mailbox quota for each user
How many
servers and databases are
required for this migration<ins cite="mailto:Mohammad%20Ashouri" datetime="2014-05-18T22:41"></ins>?
Number of the servers:
Number of the databases:
Size of each database:
Many thanks.

You will also need to check server role requirement in exchange 2013. Please go through this link to calculate the server role requirement : http://blogs.technet.com/b/exchange/archive/2013/05/14/released-exchange-2013-server-role-requirements-calculator.aspx
2TB is recommended maximum database size for Exchange 2013 databases.
Here is the complete checklist to upgrade from exchange 2007 to 2013 : http://technet.microsoft.com/en-us/library/ff805032%28v=exchg.150%29.aspx
Meanwhile, to reduce the risks and time consumed during the completion of migration process, you can have a look at this proficient application(http://www.exchangemigrationtool.com/) that would also be
a good approach for 1500 users. It will help you to ensure the data security during the migration between exchange 2007 and 2013.

Exchange server 2013 content filter rejecting all incoming messages as spam.

Hello All,
Today out of the blue our Exchange server 2013 install started rejecting any inbound message as spam. It first started with only one user not being able to receive any mail because of this anomaly and
then after 12 or so hours all users were getting their mail rejected.
I currently had the threshold set to 5 on external messages only. Internal is disabled.
I have tried setting the threshold to 8 and 9, and rebooted the server after restarting
all services just to make sure everything reset. Even dished out a IISRESET just in case. Whatever I tried still does not work.
The install is a stand alone server facing the outside world (no edge server) living
in a 2 domain controller environment with a share point farm thrown in (ESXI5.5 environment)
Everything works just fine and dandy if I disable the content filter all together. Not seeing anything in the application logs out of the ordinary. Everything was working great and the same settings I used on this server worked well for a totally different
server that runs just fine.
Any ideas?

This is what it is set at now. Completely disabled. It worked fine for quite some time filtering out spam pretty nicely then one day everyone's mail was being rejected as spam by the content filtering agent. I know of someone else who also had this
issue except their box was running 2008R2 with EX2007. They too disabled the content filter as it was giving them too many problems with mail being rejected.

You can create a PS1 file and run it in a scheduled task.
The PS1 files will need to have this.
Restart-Service MSExchangeTransport
Restart-Service MSexchangeIS
etc...
How to add a Scheduled task is given in this link.

How to install and configure ms exchange server 2007 both role hub and edge transport role in one network

How to install and configure ms exchange server 2007 both role hub and edge transport role in one network

Hi,
Edge role is design for perimeter networks, to keep security risks minimum. So it’s not recommended to have edge role in internal network. Must have separate network or subnet for edge services.
If you are playing around it in labs, then you can put edge role within same subnet as other exchange roles and no specific requirements in that case.
Thanks.

How to clone Microsoft Exchange Server 2013 configurations from one server to another server?

Hi! I need help of cloning Microsoft Exchange Server 2013 configurations from my first Server to the second Server. By doing this, the second Server will replace and run as per normal as the first Server is. How can this be done?
Thanks!

Cloning an Exchange Server is a very bad idea. Exchange is very heavily intergrated into Active Directory and this can (and honestly not to sound scary probably will) cause major issues in your environment.
Also, since you cannot have 2 servers with the same name in the same domain/network running at the same time you'll need to change the name of one of the servers. That is a huge no-no with Exchange and requires a complete uninstall/reinstall of the
product.
Now requirements differ between environments, but if you are in a scenario where you want to move from 1 Exchange 2013 (or 2010 for that matter) Server to another machine running the same version of Exchange AND (this is a big requirement for the failover
cluster piece) the Operating Systems of the machines are the same (i.e going 2012r1 to 2012r1 or 2012r2 to 2012r2 and not 2012r1 to 2012r2) you can do what Brenle suggested with the DAG and DB copies. If the Operating System of the new machine is different
(2012r1 to 2012r2) then you will will not be able to use a DAG, and will need to perform mailbox moves to move between servers.

How used single ssl for tow exchange server without clustering

how used single ssl for tow exchange server without clustering
exchange 2003 std fron-end server
used for add new server for owa failover or standby

Olivia, hopefully by now you have solved your issue but just for the sake of answering that question here so that people having the same issue can later find it I'll go through the motions:
there are a couple of ways you can achieve this.
A. get a certificate for free out there
B. generate your own self signed "fake" certificate.
certutil will certainly let you do this, here's how:
1. First, create a file/directory layout to store your certificates
mkdir -p /path/to/certificates/selfsignedCA2. Initialize a database for the certificate you want to create
certutil -N -d /path/to/certificates/selfsignedCA -P "ca-"3. Create a self-signed CA certificate
certutil -S -x -n "ca-cert" -s "cn=SelfSigned CA Certificate,dc=yourSuffix" -t CTPu -v 120 -d /path/to/certificates/selfsignedCA -P "ca-" -5Note: when prompted, select choice (5) SSL CA and 'y' for critical extensions
4. Export the your newly created self-signed CA certificate in PEM format
certutil -L -d /path/to/certificates/selfsignedCA -P "ca-" -n "ca-cert" -a > /path/to/certificates/selfsignedCA.pemthat should get you going

How to get list of Users[MailBoxes] in Exchange Server 2013 by using EWS Managed API

I was created Full Access permissions of all users to Admin user account, to access each user Mailbox programatically

We can run the following command in Exchange Management Shell to get all user mailboxes name and export it to a .csv file:
Get-Mailbox -ResultSize Unlimited | Select Name,Alias,RecipientTypeDetails | Export-Csv c:\Users.csv
If you want to retrieve the list of users by using EWS Managed API, I suggest you can ask a question in Exchange Development forum for more suggestion:

How to : Configure Project Server 2010 to work with Exchange Server 2013

I haven't seen any document with Project 2010 and Exchange 2013. You could still try the old document with Project 2010 and Exchange 2010.

How to Check Exchange Database Size with PowerShell in Exchange Server 2013

That command seems to work for me. Do you get an error when you run it? What happens? To answer your second question, the limit of the databases, the maximum supported size is about 16TB. Best practices are to keep the database to under
a 2TB or even smaller depending on your backup and recovery objectives.
