The Network Administrator

So after we had Exchange 2010 installed, and verifying all activeSync settings were correct. I kept getting cannot connect to server when setting up ActiveSync on my iPhone…This is was solved the issue…

This issue occurs if the AD user object of the Exchange 2010 user doesn’t have “Allow inheritable permissions from the parent to propagate to this object and all child objects. Include these with entries explicitly defined here.”

Once this setting is checked, Exchange ActiveSync works again.

So I ran into a situation today where my  exchange server suddenly had 100% CPU for hours. Restarted the information store providing temporary relief but the issue came back. After reviewing logs and the event viewer  I was ready to stop the information store and check the intregity of the information stores. Thankfully we found this article from Microsoft and it solved the issue, atleast it has been hours and the issue has not returned. Please note, if you have a blackberry server you will want to copy over certain  .dll files from the updated bin directory of the exchange server. Hope this saves someone some time.

Just an update the next day my issue returned…After opening a support ticket with Microsoft it looks like it may have been due to some issues in one of the information stores. After running the ISINTEG -s (servername) -fix -test -alltests  utility on that store ans now i have to wait and see if that solved my problem.
