Mailbox is an Exchange object which is used to send or receive emails and to store messages, appointments, tasks, notes and documents. In Exchange 2013, we have the below types of Mailboxes
  • User Mailbox: User Mailbox is an exchange object that is assigned to a user in your Exchange organization. We can create a new mailbox by creating an active directory user account or we can enable mailbox for an existing user account
  • Shared Mailbox: Shared Mailbox is a mailbox which will be accessed by group of users. Shared mailbox will not be primarily assigned to a user account. Shared Mailbox will be added as an additional mailbox and accessed by users. For example, Human Resource can use a shared mailbox, where employees can send their common queries as email to that mailbox. Any one from HR team will access the mailbox and reply to that emails.
  • Room Mailbox: Room mailbox is a resource mailbox used to booking conference rooms etc. By default, the active directory account for Room Mailboxes is disabled and the user having full access permission can add this mailbox or the calendar to as additional Mailbox or shared calendar. By default room mailbox will accept the room bookings, we can set a moderator whether to accept or decline meeting requests.
  • Equipment Mailbox: Equipment Mailbox is similar to Room Mailbox, where the equipment mailbox will be used for booking equipment like Projects and White Boards etc.
  • Linked Mailbox: Linked Mailbox is a special type of mailbox created in your exchange organization for user in different organization, where a trust has been established between those forests.

Special Mailboxes

  • Public Folder Mailbox: Public Folders Databases are now discontinued in Exchange 2013, but public folders exist. Public Folder in Exchange 2013 can be created using a special mailbox called Public Folder Mailbox. First created Public Folder Mailbox maintains the Public Folder hierarchy and the permission as like previous versions.
  • Site Mailbox: Site Mailbox is a new concept is Exchange 2013 which will allow a user to access the email and SharePoint documents from a single interface like Outlook 2013
Distribution Groups

Distribution Group are the active directory object which is used to send emails to a group of users.
  • Dynamic Distribution Group: This is a distribution group that uses recipient filters and conditions to derive its membership. For example, we can created a distribution group with the condition that if the department equals sales, where it will find all the users with the department name as sales and make them as member of the distribution group
  • Mail Universal Distribution Group: Mail Universal Distribution Group is mail enabled active directory group which is used only to distribute the emails.
  • Mail Universal Security Group: Mailbox Universal Security Group is a mail enabled security group which is used for setting permission for group users on a resource in the active directory and also to distribute emails to the users as members of the distribution group.
Contact

  • Mail Contact: Mail Contact is a mail-enabled active directory object which has the information about the users that exists outside of your exchange organization. Mail contact will have external emails addresses and the emails sent to mail contact are routed to external domains.
  • Mail User: Mail user is similar to Mail contact, where the Mail User will have an user account which can be used to login to your exchange organization but the mail user will have their mailbox on different exchange organization.
System Mailbox

  • Arbitration Mailbox: Arbitration mailbox is a system mailbox used for approval work flow. For example arbitration mailbox used for handling moderated recipients and distribution group member approval
  • Discovery Mailbox: Discovery mailboxes are created by default which is used to perform in place ediscovery search in Exchange 2013.

How to Change DNS to google public DNS

In this tutorial , i will show you how to change DNS from Mikrotik router OS to google public DNS. If you have a special configuration DNS from your ISP, make sure the internet stil can running up if you change it to another DNS service. In another case, Sometimes we need to change the DNS server from our ISP to another DNS service provider. If DNS service from ISP is down , we should to do something to resolve this problems to make the internet service still running well.

I wrote this tutorials because some friends ask to me how to change their DNS service to google public DNS and another DNS service provider. Ok follow this instruction.

Make sure you have been backed up the Mikrotik Router OS configuration. To doing this, see the Picture bellow and follow the instruction:

1. Open your Winbox
2. Go to "File" and clik Backup




Ok, if you have finished the first steps, change your DNS service with this steps :

1. Go to "IP > DNS > SETTING > change the DNS with Public DNS. The Google public DNS is 8.8.8.8 as primary servers and 8.8.4.4 as secondary servers. see the pic bellow :

How to Setup Mikrotik Router OS

After i wrote article about how to install Router OS on a Pc's, Now i will show you how to configure the Mikrotik Router OS as a Internet Gateways. For your information, to setup the Mikrotik Router OS you can use some metode. First, We can configure directly from the pc's . Just turn on the pc and you will show the login screen after the boot process finished.

Second : We can use the small tools from mikrotik with Grapic user Interface,The tools is a magic tools, Mikrotik give the name as Winbox . But on this article i will guide you to setting up the router Os with the first methode. Unfortunetly with this methode you will setup the router with command line interface. But don't worry, you can copy paste my configuration for the first time before you understand the command line function.

If you copy-paste my configuration, Make sure the Network topology on your home is same as with this tutorials.

For the first : Setting up your DSL Modems or your internet connection with this parametre :

Modem Ip/ Internet Ip : 192.168.1.1
Your Laptop/workstation IP : 192.168.0.10

We will start the configuration :


system identity set name=MyNet
ip address add address 192.168.1.2/27 interface=ether1
ip address add address 192.168.0.1/24 interface=ether2

Explanation :

-System identity is a identity of aour routers, you can change with what ever you want
- Ip address 192.168.1.2 is an Ip address which will comunicated with the Modems Ip to the internet
- Ip address 192.168.0.1 is a default gateway for the client/your computers
- Ether1 is an interface, you must connetcting the Modems with the UTP cable to ether1 port
- Ether2 is an interface which connecting your laptops or your PC client/switch. Remember, you must be connecting with this port if you wanna conect to the internet with your pc.

Next step : Add the internet gateway
add comment="" disabled=yes distance=1 dst-address=0.0.0.0/0 gateway=\
192.168.1.1 scope=30 target-scope=10

192.168.1.1 is your Modems Ip

Next : DNS Setup

/ip dns
set allow-remote-requests=yes cache-max-ttl=1w cache-size=2048KiB \
max-udp-packet-size=512 servers=8.8.8.8,8.8.4.4

8.8.8.8 and 8.8.4.4 is a google free DNS service. You can use your own parametre from ISP's

Before i show you the next steps, you must test your connection with ping command to the DNS servers :

ping 8.8.8.8
8.8.8.8 64 byte ping: ttl=242 time=255 ms
8.8.8.8 64 byte ping: ttl=242 time=243 ms
8.8.8.8 64 byte ping: ttl=242 time=247 ms
8.8.8.8 64 byte ping: ttl=242 time=243 ms
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 243/247.0/255 ms

If the DNS replayed , you have been succed to configure the router to cominicate with the DNS servers and Internet

As long as, your router have been succes to comincating with the internet, But your computer Can;t do it. We must create the rules to NAT the Internet to your computers.

add action=masquerade chain=srcnat comment="" disabled=no out-interface=\
ether1

You should to change your ip address configuration on your laptops to the static IP.

for the exmaple :

Ip address : 192.168.0.20
netmask : 255.255.255.0
Default gateway : 192.168.0.1
Primary DNS : 8.8.8.8
Secondary DNS : 8.8.4.4

This is it, you have been succed to configure the Mikrotik router os as a Internet Gateway. In the next article i will show you how to configure mikrotik with Grapic user interface using a tools called Winbox. I hope this article can help you. Thanks
