Introduction I regularly meet with customers and discuss their Exchange Server architecture. Two topics frequently come up so I thought I'd discuss them with everybody and give my perspective on them. Many customers tell me that they do not impose mailbox and/or message size limits on the...

Recent question I heard sounded really interesting: Anyone know a way to add many addresses to the IP Allow List at one time versus one at a time?

Ensuring that your servers are operating reliably and that your mailbox database copies are healthy are primary objectives of daily Exchange 2010 messaging operations. Of course you must actively monitor the hardware, the Windows operating system, and the Exchange 2010 services. But when running in an...

We have always recommended that customers prepare formal server build documentation for their Exchange environments. Until now, we've not provided any formal guidance around what that documentation should look like. We now have build documentation templates and instructions for preparing a build automation...

What is DomainPrep? Why does Exchange recommend running DomainPrep on the Root Domain if there are no Exchange servers or users in that domain? I have been asked these questions so frequently I thought I’d do a post on it. I know DomainPrep is a little mysterious to many people so let me quickly...

Someone asked the following, so I thought I would try and address the issue as I think it is one that is commonly misunderstood: Could you enlighten us on what happens when an Outlook user uses the permissions tab on a folder to grant access to other users? It apparently isn't the same as when...

I wanted to give you a quick pointer to a very interesting blog post that discusses the subject of Exchange database fragmentation on incorrectly formatted NTFS volumes, what the ramifications of those situations can be and how to deal with them. It has been written by Mike Lagase on his blog and can...

This...

This blog post will explain what the flow of the client access a BE server through a FE server looks like, including access to domain controllers that has to happen as part of this process. The illustration...

A question that has come up several times in recent months is: How do I create RBAC roles that present only very limited ActiveSync management functionality?

This post applies to Exchange 2010. By default, PowerShell has 7 Cmdlets loaded in the remote session for "import-session *" scenario which leads to about 30 MB of memory spike.
