Hi.We have exported the old certificate from our 2003 server to new 2010 exchange server. Everything seems to work, but I can not delete Exchange's self signed certificate. Receive the following message: ”The internal transport certificate can not be removed because that would cause the Microsoft Exchange Transport service to stop. To replace there internal transport certificate, create a new certificate.” Services for this "self signed" certificate is now SMTP. We also have SMTP in the new. Should we delete the old "self signed” certificate that was installed during the installation of the 2010 exchange server? or is it okay that it is not removed?

If y ou don't need it, delete it Full time IT consultant since 1998 mainly on Exchange\ISA\AD MCSE NT4.0,2000/2003, CCNA MCITP: Enterprise Messaging Administrator 2007/2010 MCT since 2001

Ensure that the certificate you imported is enabled for SMTP. Then you should be able to delete the self-signed certificate. Get-ExchangeCertificate should show you your certificates and for which services they are enabled.-- Ed Crowley MVP"There are seldom good technological solutions to behavioral problems.".

Thank you! It is eneabled for SMTP. I wonder if the old is causing some of the problems we have: This does not work: • We can not see free/busy information in group plan or the scheduler for meetings (Outlook 2007) • Availabillity service is not working • Download Offline Address Book from Outlook 2007 does not work. (On the Tools menu, point to Send/Receive, and then click Download Address Book. Gives the following error message: The task Microsoft Exchange Server report error 0x8004010F) This works: • OWA is working from outside and innside (Here you can se free/busy in the calendar) • Active-sync for mobile is working (syncing calendar, contacts, mail) • Sending mail in and out of work. • Receive mail from outside and inside • Outlook 2007 works (no questions about the certificate anymore)

I keep it, because every problem is solved.

All three "not work"s are related to Exchange Web Services. I can't tell you why that isn't working without poking around on your system. You might run: Get-WebServicesVirtualDirectory | Format-List and see if you notice anything that isn't right, especially the internal and external URLs.-- Ed Crowley MVP"There are seldom good technological solutions to behavioral problems.".

Thank you! Problem solved. I found that auto-discover virtual directory did not have a url. When I put a internalurl to “https : / / mail.mydomain.com / auto discover / autodiscover.xml” everything acted as they should. (Exchange Web Services use auto-discover)
