Getting fed up with 0xC7FE1F42? Well you aren't the only one, here's a quick list of reasons I've found that causes this, and more importantly how to get around it.

Firstly make sure the store you are trying to restore too is offline i.e not mounted.

This is done via ADSIEdit (install from the Windows 2003 CD folder SUPPORT\TOOLS\SUPTOOLS.MSI) then c:\program files\support tools\adsiedit.msc

1.	Open ADSI Edit.

Yet another ballache with Exchange 2003, here's a quick summary to perform this 'simple' task.

Firstly get pfmigrate.wsf , for some reason most documentation pointed to the CD which was annoying, the latest version is available here with the exchange deployment tools

So let's try and migrate those public folders:

pfmigrate.wsf /S:elephant /T:spider /A /n:100

When creating meeting requests in shared calendars I found all users were getting replies (i.e acceptances or denies) when they were added as an attendee.

To stop this from happening the option is in quite an obscure place, at the following:

tools->options->delegates tab

In the list of delegates you need to select each one and click permissions, then UNTICK the delegate receives copies of meeting-relates messages sent to me

To address this issue,

First make a backup of the MetaBase:
Open IIS Manager
Right click on server->All Tasks->Backup/Restore Configuration...
Click Create Backup
Give the backup a name (e.g. 'Backup before fix')
Click OK, Close

Then enable direct Metabase Edit
Open IIS Manager
Right click on server and go to Properties
Check "Enable Direct Metabase Edit"
Click OK

Open the file C:\WINDOWS\SYSTEM32\INETSRV\METABASE.XML from Notepad.

Look for <IIsWebVirtualDir Location="/LM/W3SVC/1/ROOT/Microsoft-Server-ActiveSync"> and just below it, you
will see:

If like me you were too cheap to buy an expensive Verisign or similar SSL cert just to get Activesync working, knowing a cheap cert should do the same thing then p12imprt could be just what you are looking for.

No amount of installing the cert to personal or root stores on my mobile device (O2 XDA running windows mobile5) would help with getting activesync running (lots of 80072F17 errors) but the below did:

Get a copy of the cert from your actual server
