In response to the amount of comments I’ve had (which are way way more than I was ever expecting!) on my Exchange Mailbox Recovery article, I’ve written a script to convert your guids from the bad format that exmerge gives you to the one thats required for updating the user account.
You can access it here. Please leave any feedback on this post.
If you find this article useful, buy me a beer!
Super helpful, many many thanks.
Hi,
I had found your documentation on this site some time ago and it was wonderful in allowing me to complete a restore of a email box for a user who had been deleted then recreated onto a different mail store. I had the same thing today and came back to your site to get my head around the guid convert to discover your conversion tool. It is, as the other users have said, a life saver. Thank you thank you thank you
Thanks man! Makes the life of an administrator easier! ;o)
Bloody marvellous, helped me no end. Thank you. I did the convert manually and did not trust myself with the result I got. I used this tool and it was exactly the same as my result.
I applied the changes to the user in AD I was editing and hey presto all my exchange restore problems went away.
YOU sir, are an absolute LEGEND.
my next 48 hours of work just got a hell of a lot less stressful 
you need a ‘buy me a beer’ link on here.
Cheers,
David
@David – added! 
Thanks! I had tried to do a restore like this before and could never figure it out. This worked perfectly!
Mark
good, i need it right now.
I was cacking myself that the restore I had just performed just wouldn’t Exmerge properly so I decided to Google and ended up here. Entered my wacky old nonsensical GUID and converted it via this tool…but it didn’t work! I eventually realised that was because I was accidentally typing in the word ‘slippers’ instead of the GUID and once I rectified this, it worked a treat.
Thank you so much for clearing up my cack!
Amazingly helpful!
Thank you!
Hi! I was surfing and found your blog post… nice! I love your blog. Cheers! Sandra. R.
Heh,
I was raking on how to do this for work, took me a good 10 mind before I realised it was your site!
Heading to the next meet?
Can’t make the next LUG meet – maybe next month!
I’m determined to make an effort again!
Not sure that this converter correctly interpreted my GUID:
Original GUID: u\D6\13\26\13lBL\8F9\E8i7\3F\C7\E0
Converted w/tool : 75 D6 13 26 13 6c 42 4c 8F 39 E8 69 07 3F C7 E0
Here is how I was interpreting it.
u D6 13 26 13 l BL 8F 9 E8 i 07 3F C7 E0
^ ^ ^ ^
75 6C 39 69
75 D6 13 26 13 6C BL 8F 39 E8 69 07 3F C7 E0
Guess I’ll find out which one works by trial & error
…and your tool was correct, thanks!
I just got into exchange admin roll so I’m all about anything that will make my life easier….Thanks again
Any chance of you making a stand alone utility for this so i don’t have to rush to your website, and hope it’s still around?
My Friend – you are a genious. Your instructions and GUI tool are top notch!! Not for the novice, but turned a potential disaster into success. Saved me hundreds on buying one of those EDB recovery tools from the web.
Thanks!!
Marvelous! That helped so much I had to “Beer You”!
Awesome tool to complement an awesome article – many thanks!
Great tool and article! Thank you!
Hi
FIRST OF ALL A BIG THANK YOU….

A BIG HUGE THANKS ONCE again..
This is very very helpful, Mark you are way more than Brilliant

Here is the beer
This is really a great tool & article.
Cheers! This info and tool has saved a 3GB mailbox that failed to export properly with Exmerge – saved my bacon. It seems Exmerge does not like mailboxes greater than 2GB … watch out …
Thanks! Great Work!
Best regards from Poland!
