Migrating from legacy mail system ?

There are lot of tools which allow you to migrate from older mail system to Exchange. Most of them are not free, but there is 1 tool which i found very useful and it’s free.

Introducing Imapsync.

This is a Linux opensource tool, you need to download it, untar and install it.

The command will look like this:

imapsync --host1 123.123.123.13 --user1 john@contoso.edu.my --password1 Myp@ssw0rd -authmech1 LOGIN --host2 111.111.111.111 --user2 john.smith@wordpress.com --password2 Dtbqzgd6 -authmech2 PLAIN

to capture the log file :

imapsync --host1 123.123.123.13 --user1 john@contoso.edu.my --password1 Myp@ssw0rd -authmech1 LOGIN --host2 111.111.111.111 --user2 john.smith@wordpress.com --password2 Dtbqzgd6 -authmech2 PLAIN >  log6 2>&1 &

host1,user1,password1,authmech1 are compulsory fields, they denote the source. host2,user2,password2,authmech2 denote the destination.

Take note that the destination authentication method is “Plain Text”, hence in Exchange you need to change the method(imap) to plain and not SSL or TLS. I just migrated 700 users from surgemail and for surgemail authentication method, it will be “Login”.

After running the command, the result will either be failed or passed, here some examples :

Example 1-Passed:

log57:Failure: error login on [123.123.123.13] with user [john@contoso.edu.my] auth [LOGIN]: 2 NO login failed john@contoso.edu.my password wrong or not a valid user

Take note of the mentioned IP, the above example indicate the source ip, it could mean the password is wrong, the user dont exist or the account was suspended. Hence, please verify the source account.  If the ip is referring to the destination, check the account, unlock the password, reset the password if necessary.

That’s all for now, thanks for reading.

Exchange 2013 : Reset user password in ECP

Have you ever wanted to reset user password via ECP ? For Exchange 2010 and below, it is not possible, you have to login to server and do it.  But with Exchange 2013, you can reset user password via the browser, also known as EAC.

Let me introduce you the RBAC !

You heard of it, but have you ever use it? You should !

OK, let’s get started !

1:  Before you can add the “Reset Password” role, you need to install it. Let’s see if this role is installed by default :

Get-ManagementRole "reset password"
The operation couldn't be performed because object 'reset password' couldn't be found on 'VM-AD5.andrew.com'.
    + CategoryInfo          : NotSpecified: (:) [Get-ManagementRole], ManagementObjectNotFoundException
    + FullyQualifiedErrorId : F1EF706,Microsoft.Exchange.Management.RbacTasks.GetManagementRole

Notice by default, this role is not installed.  Let's install it now.

2: 

  • Launch Exchange Management shell.
  • Type Add-pssnapin microsoft* and hit enter.
  • Type Install-CannedRbacRoles and hit enter.
  • Type Install-CannedRbacRoleAssignments and hit enter.
  • Close and relaunch EMS.

3:  Let’s verify.

Get-ManagementRole “reset password”

Name                                                    RoleType
—-                                                        ——–
Reset Password                                ResetPassword

If you performed step 2 correctly, you should see the new role.

4:  Now, we would like to add resetpassword role to Help Desk.

New-ManagementRoleAssignment -SecurityGroup “Help Desk” -Role “Reset Password”

(you can do this in ECP too)

5:  Next, open the EAC. For example https://yourcompany.com/ecp

6:  Click on permission, select a user and click edit.

7:  Viola !! You are done !
