Over the past few days, some of our readers have reported an Exchange 2007 autodiscover certificate error.
Quick and Easy PC Repair
I had to scratch my head several times before I found a solution to the problem. This happened to two of our visitors and could easily happen to another. Hope this helps.
We have been large customers using Outlook 2003 and 2007, depending on the age of our computer and our needs for Outlook. All of a sudden, all Outlook 2007 computers started using the infamous automatic OCR certificate verification. Error, enjoy the following:
I have verified that Exchange (2007) is configured very well for the internal autodiscover URL. Enter the Open Exchange 2007 Management Shell command as shown below.”Get-AutoDiscoverVirtualDirectory”. It was created to help you with mail.domain.com. I also confirmed the internal DNS, but this is not a problem. I then have an achievable goal of having both clients use a completely different company to host their DNSs. I consulted with them people and both also created a default DNS entry for *.domain.com. The problem is that Outlook 2007 tries to allow them to connect to Autodiscover whether or not it exists, and even if that computer is in a domain, in order to be local to the server. Delete my default is Allowed Shipment for both clients.
Note that there is no custom autodiscover SRV record in any client DNS. So I asked them to also link it: _autodiscover._tcp.domain.com 8 0 443 mail.domain.com
This enabled the autodiscover career with our current and only possible certificate pointing to mail.domain.thus com, enabling autodiscover for all ActiveSync enabled devices.
By the way, one of the majority of these clients is running a Mac running OSX Lion. Built-in Apple Mail user won’t connect to Exchange if auto-detectDoes not work properly. (At least that’s what I found.)
Hope this helps someone else!
Regarding the main problem with the autodiscover certificate, Microsoft recommends that many of you provide all the required DNS names in the same file. A certificate uses a Unified Communications certificate if it supports the Subject Alternative Name operation field. The use of unified certificate linking reduces configuration complexity and Manage the Autodiscover service and Exchange agency URLs.Enjoy a faster
