Create mail relay in Exchange 2007 & Exchange 2010

You may want to create an open mail relay in Exchange to allow other servers to relay mail through your exchange server.

There are 2 steps:-

1. Create a new receive connector in the management console. In the “permission groups” tab, check anonymous permission and put the IP address of the server that you want to permit relay from. In the example below I have called the receive connector “Allowed Relays”

2. Open the exchange management shell and enter the command: Get-ReceiveConnector “Allowed Relays” | Add-ADPermission -User “NT AUTHORITY\ANONYMOUS LOGON” -ExtendedRights “Ms-Exch-SMTP-Accept-Any-Recipient”

Manually Remove Exchange 2007

Avoid reinstalling the OS so I tried removing exchange manually.

1. Run setup /m:uninstall
2. Stop and disable all the Exchange 2007 services
3. Use Registry Editor (Start->Run->Regedit) to remove these Exchange related registry keys:
• HKLM\SOFTWARE\Microsoft\Exchange
• HKLM\SYSTEM\CurrentControlSet\Services\MSExchange* (all the keys starting with “MSExchange”)
• HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft Exchange
4. Remove the entire Web Server role (don’t forget to reinstall afterwards as it’s a prerequisite for E2K7!)
5. Remove the Exchange 2007 server from Active Directory. I ended up deleting the entire “Microsoft Exchange” branch from ADSIEdit (Configuration Container > Services > Microsoft Exchange) as my Org only counts one server.
6. Use Windows Explorer to delete:
• C:\Program Files\Microsoft\Exchange Server
• C:\ExchangeSetupLogs
7. Use Windows Installer CleanUp Utility to remove all the exchange related info from the installer database.
8. Remove the security groups created by Exchange setup from AD

Note: Manually removing Exchange 2007 is not supported by Microsoft! Official guidance for removing Exchange 2007 can be found in this TechNet article.

Searching for Large Items (exchange)

Best Practice Definition

Retaining unnecessary messages, especially those that contain large attachments,  quickly takes up the storage space on the Exchange server. This can lead to a crash of the server, leading to down time for users. Thus, it is important to apply correct storage practices to these messages. (Exchange is not meant for long term storage of information!)

Best Practice Usage

One of the easiest way to clean up storage space is to go after the largest items first.  Here the steps to find the large items you have in your mailbox:

·         Along the left hand side, near the top, click on the item that starts with “Mailbox”.

·         Go to Tools, Find.

·         Click on the Advanced button.

·         In the upper left hand corner, type “200” in the box next to “At Least” item.

·         Click on OK

·         Click on Find Now.

Once these search results are completed, you can sort the items by Size (click on the Size bar) and concentrate on removing the larger items first.   Please follow the best practices for saving 

Retaining Individual E-mail Messages

Best Practice Definition

Retaining unnecessary messages quickly takes up the storage space on the Exchange server. This can lead to a crash of the server, leading to down time for users. Thus, it is important to apply correct storage practices to these messages. (Exchange is not meant for long term storage of information!)

Best Practice Usage

When you receive a message that you need to save beyond 365 days, you should save the message in your "My Documents" directory on your hard drive (which is backed up to your O: drive daily).  After saving the attachment, delete it from the message or delete the entire message itself.

Steps to save a message:

·         Highlight or Open the attachment and choose "File", "Save As".

·         Select the appropriate directory in My Documents (preferred storage location).

·         Select the File Type RTF format for text only                                                                                                      MSG format to save as message format with attachment 

·         Click OK.

·         Delete the original Message.

Steps to save multiple messages

                       

·         Open explorer session and create folder for messages to be saved in

·         Open outlook

·         Go to the outlook folder (eg Inbox)and select multiple messages to move. You can select non-adjacent messages by holding down the CTRL-key                                        

·         Ensure all messages to move are highlighted.

·         Click and drag to start tool bar – ensure cursor is over explorer session

·         Explorer session will maximise

·         Drop messages into required directory.

·         Check that messages have copied across OK

·         Delete messages from outlook

NOTE:

If your message has the same subject line as an existing one in the destination folder, it WILL OVERWRITE the original message.

When copying multiple messages – all  messages should be highlighted at message level not folder name. Complete folders cannot be copied across by the folder name -  this will create shortcuts to the original message.

Always check that the messages have successfully copied across (and ensure that they are not shortcuts) before deleting them from outlook.                               

           

===============================================

Ensuring that the Deleted Items Folder is set to “Empty on Exit”

Best Practice Definition

Until the final implementation of the “Automatically Delete messages in the Deleted Items folder after 2 days” process is implemented, this is a good area to look for wasted storage.

Best Practice Usage

·         Go to Tools, Options.

·         Select the General Tab.

·         Make sure that the check box labeled “Empty Deleted Items folder upon exiting” is checked.

===============================================

How will I know when I am reaching the maximum size limitations?

·         Warning messages when total size of mailbox is approaching the maximum allowed.  The message will look like this:

You are exceeding the size limit set on your mailbox by the system administrator.

Ex. 

Your mailbox size limit is 92460 Kbytes

You are currently exceeding this limit by 11453 Kbytes

You may not be able to send new mail until you reduce your mailbox size. To free up space, delete any items that you are no longer using or move them to your Personal Folders.  Items in all of your mailbox folders including the Deleted Items and Sent Items folders count against your size limit.  You must empty the Deleted Items folder after deleting items or the space will not be freed.

·         Rejection message from “system admin” when trying to send a message if the mailbox size exceeds the preset limits.

·         Rejection message from “system admin” if the message is too large.

·         When a user exceeds the Mailbox size limit, they will still be able to receive messages, but will not be able to send new messages until they remove some of the material from their mailbox.

How can I recover deleted items? (Exchange)

The deleted items folder is kept in an archive for 7 days (Depend upon your Policies) after the messages have been deleted.

They may be recovered anytime within this 7 day period by doing the following :-

:

·         Open Outlook 98

·         Select “Deleted Items” folder

·         Select “Tools” from the menu bar

·         Choose “recover deleted items” from the drop down menu

·         Select all items you wish to recover

·         Click on the button  “ Recover selected items”

·         The deleted items will then be restored to your “Deleted Items” folder

Please Note :

The recovered messages will be deleted again from the deleted items folder when you exit outlook so they should be moved immediately to another folder outside of exchange if you wish to retain them.

Please refer to Exchange Best Practices document on your local shared drive in Help Desk Information folder for more instructions.

Deleted items will not be recoverable after seven days.
