Replicating Public Folder From Exchange 2000/2003 to Exchange 2007

Public Folder will need to replicated to Exchange 2007 before retiring the old Exchange 2000/2003 server.

Thanks to PFMigrate, no longer need to manually add the replica from the hierarchy and remove it after replication. To do this:

1) Download the PFMigrate from Microsoft Website.
2) To create a report of current public folder replication:

pfmigrate.wsf /S:OLDEXSERVER /T:NEWEXSERVER /R /F:C:\PFRpt.log

3) To replicate the System Folder:

pfmigrate.wsf /S:OLDEXSERVER /T:NEWEXSERVER /SF /A /N:10000 /F:C:\PFSYSRpt.log

4) To replicate other Public Folder:

pfmigrate.wsf /S:OLDEXSERVER /T:NEWEXSERVER /A /N:10000 /F:C:\PFALLRpt.log

5) To remove the replica from old exchange server:
NOTE: Please remove after few days, letting the replication to take place.


Thats it.

Attachment Filtering in Exchange 2007


Do you know what we can apply attachment filtering in Exchange 2007? Yes, it is free.

However, you will only be able to configure this in Exchange Management Shell.

Detail about this, you can utilise Outlook 2007, AD and Exchange 2007 for attachment filtering.
1) Outlook 2007 has 2 level filtering. Level 1 filtering means attachment that not allowed. Level 2 filtering will prompt the users to download prior running it. By default, there are nothing in level 2.
2) Using group policy, administrator can "open up" Level 1 attachments to users so they can choose whether to accept the attachment.
3) Using Exchange Management Shell in Exchange 2007. This is the cool thing to share. , to use Management Shell, few things to know: Get, Add, Remove and Set.

Example, you would like to know whether the filename is being block:
Get-AttachmentFilterEntry filename

To add an attachment:
Add-AttachmentFilterEntry -name VIRUS.EXE -type FileName
Add-AttachmentFilterEntry -Name image/jpeg -Type ContentType

To remove:
Remove-AttachmentFilterEntry -Identity filename:virus.exe

To set the action after block:
Set-AttachmentFilterListConfig -Action Reject -RejectResponse "This attachment is Virus"

Seems cool till here? Something to share, not that good news, above mention cmdlet only available in Edge Transport Server, not the Hub Transport.

POP3 in Exchange Server 2007


We got a request on how to setup and manage Exchange 2007 POP3. Interesting enough, as some concept you will need to know.

POP3 is one of the service and supported protocol in Exchange 2007. However, by default, the service is not started.

We do not recommend you to use POP3 unless it is a need. Try to use Outlook Anywhere or OWA to replace it.

To enable it, simple change the POP3 service to start automatic, start the service. One concept to know - security is a main concerns, thus the POP3 started only support a secure login, m,eans with Certificate. For those that do not want this setting,

Go to Exchange Management Shell, type:

to know more information about your existing POP3 configuration.

Set-PopSettings -LoginType PlainTextLogin
to change the login type from SecureLogin to PlainTextLogin.

Remember to restart the POP3 service. There you go.

Hold on, how to manage via Management Console? There are no GUI for you to manage POP3.

DOS- TIP 1 - Store my password

Dear Guys,

DOS is actually the most basic OS to learn. Something to share on the years experience:

How to store my bank account number, personal password +++?

Lets see this copy command in Windows 9x, Windows 2000, Windows XP...

Do you know that you can join to similar files to one file? Let say you downloaded three movies file, 1.mpg, 2.mpg and 3.mpg. Its not cool to open file by file when watching it. Why not combine those three files?

Some of you all will say, i can use third party tools! Anyway, if you can perform this using DOS, why not?

the command show like this: copy/b 1.mpg+2.mpg+3.mpg result.mpg

It is just that simple.

Hey, thought you are sharing on storing my password?

Ok, thats hohw it works. Let say you have one of your travel picture, 1.jpg. You stored your password in one txt file called pass.txt.

type this command:

copy 1.jpg/b + pass.txt/a newpic.jpg

Delete the pass.txt file.

Thats it.

When someone open your file by clicking newpic.jpg, they will only see the picture. To view your password, use notepad to open the newpic.jpg. Ctrl + End, you will then see your password.
