LDAP send queue limits cause event 2070 and 2084

I recently worked on an issue where the domain controllers kept intentionally disconnecting the Exchange servers. The error messages that described the reason for the disconnect were rather misleading, and we ended up wasting quite a bit of time taking steps that had no chance of improving the situation. In this blog post, I'm going…


Cleaning up Microsoft Exchange System Objects – part 2

In a post last month, called Cleaning up Microsoft Exchange System Objects (MESO), I described how to determine which objects can be eliminated from the MESO container if you have completely removed public folders from your environment. But what if you still have public folders?


Event 9414 means your OAB is missing objects

Today, I want to highlight a behavior that isn't really called out anywhere in any existing documentation I can find. This is the behavior that occurs when Offline Address Book generation on Exchange 2010 logs an event 9414, such as this one:


Mailbox lock contention in Exchange 2013

We're seeing some cases where contention for the mailbox lock causes errors on Exchange 2013. In a post over on my new blog, I describe how to identify this situation: http://bill-long.com/2014/02/07/mailbox-lock-contention-in-exchange-2013/

Moving from TechNet blogs to Jekyll on Windows Azure

For nearly a decade, I've been occasionally blogging on the Exchange Team Blog, and later on my personal TechNet blog. Those platforms are stable, easy to use, and perfectly acceptable. But they're not much fun. I want something I can tweak, break, and put back together again.


Fixing Mail Enabled Public Folders per KB 977921

I admit it. I have gotten lazy about posting my new scripts, and haven’t posted anything in forever. Today, someone emailed me about the KB 977921 problem, where a public folder has a directory object but is not flagged as mail-enabled. I wrote a script for this a year ago, and never posted it. So,…
