TomHD Posted January 23, 2015 Posted January 23, 2015 Hello All, Trying to uninstall our old Exchange 2007 from a Server 2003 R2 VM. Have gone Control Panel>Add/Remove Programs>Exchange 2007. I deselect all the server roles and select next. Readiness Checks fail with "Error: Active Directory does not exist or cannot be contacted" I have Googled this but the resources I find seem to be centred around installation and not uninstalling! Any help would be greatly appreciated Thanks, TomHD
jamesreedersmith Posted January 23, 2015 Posted January 23, 2015 Check your DNS entries are pointing to correct and active Domain controllers.
TomHD Posted January 23, 2015 Author Posted January 23, 2015 So the virtual machine is on 10.xxx.xxx.226. There is no entry in DHCP for this IP and I'm not sure what I should be looking for in the DNS?
TomHD Posted January 23, 2015 Author Posted January 23, 2015 I have managed to fix the AD error, the server did not have a preferred DNS set! I now only have 1 error on the Readiness Check. Summary: 3 item(s). 2 succeeded, 1 failed. Elapsed time: 00:00:06 Mailbox Role Prerequisites Failed Error: Uninstall cannot continue. Database 'Public Folder Database': The public folder database "MAIL\Second Storage Group\Public Folder Database" is the default public folder database for the following mailbox database(s): MAIL\First Storage Group\Mailbox Database . Before deleting the public folder database, assign a new public folder database to the mailbox database(s).

I looked at the recommended action but got a bit lost :\ Thanks TomHD
truebluesteve Posted January 24, 2015 Posted January 24, 2015 Don't have a solution but am interested in the thread as I'm going to decommission my Exchange Server 2007 on Monday as we have now moved to 365. I have a physical 2003 server but that shouldn't make any difference. Will let you know if I get the same issues as you!
bart21 Posted January 24, 2015 Posted January 24, 2015 Give this a try https://technet.microsoft.com/en-us/library/aa998329%28v=exchg.80%29.aspx
truebluesteve Posted January 27, 2015 Posted January 27, 2015 Did you get this sorted - I had many of the issues you had and have finally managed to get it uninstalled. I really have no idea why MS made it such a difficult task! Anyways, if you're still stuck then let me know
TomHD Posted January 28, 2015 Author Posted January 28, 2015 I'm still stuck with this @truebluesteve: Mailbox Role Prerequisites Failed Error: Uninstall cannot continue.

Recommended Action: http://go.microsoft.com/fwlink/?link...7-72288ac15f60 Thanks, TomHD Hi Tom I didn't get that exact error about the Public Folders but the one I did have was resolved with the following script - run from the Exchange Management Shell Get-PublicFolder -Server "\" -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server -Recurse -ErrorAction:SilentlyContinue Get-PublicFolder -Server "\Non_Ipm_Subtree" -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server -Recurse -ErrorAction:SilentlyContinue if you replace with the name of your server all works fine (need to replace it 4 times) Let me know how you get on Steve 1

I really have no idea why MS made it such a difficult task! Anyways, if you're still stuck then let me know Did you have to do anything on the Office365 or dirsync side of things? we have had our exchange 2007 VM switched off for the last 2 weeks and going to uninstall it as we are now on Office 365 with dirsync running.

No - all the mailboxes that we wanted migrating had gone, so like you we turned it off for a week or so and waited for the phone calls :-) None came and we haven't had any other issues so I was happy to remove Exchange 1

Did you just simply uninstall from Add remove programs or did you follow another process? Did you also remove all mail boxes before uninstalling? Edited January 28, 2015 by techie08
truebluesteve Posted January 28, 2015 Posted January 28, 2015 I used add-remove programs which is the approved method. You just untick all the roles you want to remove (which will be all of them) and wait for the errors to appear! Exchange is linked into AD which is why its best to uninstall it using the official method
techie08 Posted February 2, 2015 Posted February 2, 2015 Just out of interest, when you uninstall exchange, does it remove the "proxy address" field in attribute editor for AD users?
