Recovering Public Folder Items Easily in Exchange Server 2003

I occasionally get requests from clients and colleagues asking me to recover Public Folder items from Exchange Server 2003.

Thankfully for me I performed the ultimate fubar while performing a test migration from NT4.0 + Exchange 5.5 to SBS 2003 Premium back when SBS 2003 first came out. That's right, I managed to blow away the majority of the Public Folder store in one fell swoop, simply because I wasn't following my own instructions properly and wasn't used to the new Exchange System Manager interface.

Thankfully, I had just been getting familiar with the new capabilities of Outlook Web Access and had used the Recover Deleted Items feature to get familiar with it and to be able to instruct clients on how to use it.

I didn't really want to have to spend the time re-copying the Public Folder store from the Exchange 5.5 install, so I looked for the Public Folder equivalent of the Recover Deleted Items feature for the mailbox. It appeared to be missing. Or was it?

I had noticed that the Recover Deleted Items window had essentially opened the Deleted Items folder in the mailbox and had set a URL variable. The variable and its setting was:

cmd=showdeleted

Being the lazy kind of guy I am - as well as being inquisitive - I thought I would give some link hacking a try. I opened up the Public Folders link, navigated to the parent folder of the folder I deleted, right-clicked on the parent folder and selected Open in new... This opened the folder in a new window. The URL of this folder was of the form:

https://server/public/Public%20Folder/?Cmd=contents

I then replaced contents with showdeleted. The URL then looked like:

https://server/public/Public%20Folder/?Cmd=showdeleted

Ta da! The folder I trashed was now visible and capable of being recovered, which saved me additional copying time. Sometimes screwing up a test environment is a great way to learn a new, lazy technique :-)

Small Business Server 2003 - The Dreaded 5 CAL Reset Issue

A runaway process on SBS2003 decided to fill up all the disk space on C: in the early hours of the morning. The fallout from this was the System log was corrupt and the SBS license data was reset to the default 5 CALs.
The System log was easy to fix - reboot the server.
The SBS license data was an absolute pain. I'd never run the "Back up licenses" utility in the Licensing section of Server Management. Microsoft have KB article 888818 discussing this, which is either re-enter the licenses, restore the C:\WINDOWS folder or restore a backup of the licenses.
The first wasn't an option as I was offsite and the person with the key to the safe wasn't in. The second was just not viable - why Microsoft couldn't specify which file/folder needed restoring I don't know. The third would have been OK if ever I had run it.
After much stuffing about I found that the SBS2003 licenses are kept in the licstr.cpa file in the WINDOWS\system32 folder. Thankfully, Microsoft actually keep an automatic backup of this in autolicstr.cpa. The simple process was to stop the License Logging Service, rename licstr.cpa to licstr.cpa.old, then copy autolicstr.cpa to licstr.cpa. After this I started License Logging Service and used Server Management to confirm that the licenses had been restored.

Exchange Server 2003 Mailbox Recovery Using Recovery Storage Groups, NTBackup and Exmerge

OK, this is my quick-n-dirty guide to recovering a mailbox from an Exchange 2003 system. I'll tidy it up later.

• Enable This Database can be overwritten by a restore


• Run NTBackup, select Restore and Manage Media, find the correct media, expand the Exchange Information Store and select Logs and Mailbox Store.


• Click Start Restore, Restore to <server name>, and set the Temporary location to the file location used to create the Recovery Storage Group. Enable Last Restore Set.


• After the database has been restored, mount the Recovery Storage Group database using Exchange Server Manager.


• Run Exmerge and select Extract or Import (Two Step Procedure).


• Select Step 1.


• Enter in <server name> for Exchange Server Name.


• Select Recovery Storage Group database.


• Select Mailbox to recover.


• Select Folder location to save .PST files to.


• Start ExMerge, click Next


• Choose Extract or Import (Two Step Procedure)


• Pick Step 2: Import data into an Exchange Server Mailbox


• Again type the name of your Exchange server then click Next


• Mark the mailboxes you want to merge, click Next twice


• Specify where the .PST files should be merged from and click Next


• Check mailbox data, then Dismount RSG database and remove files from the RSG file location


• You're done!
