Enable-RemoteMailbox – Is It A Chicken Or An Egg

Posted on by Rhoderick Milne [MSFT]

This post is to answer a recent customer question regarding if there is a requirement to perform a directory sync cycle after creating a new remote mailbox enabled AD user object before it could have an Office 365 mailbox created.

They believed that the on-premises Exchange tools were directly reaching out to Exchange Online and immediately creating the necessary mailbox in the service.   This is w… Read the rest “Enable-RemoteMailbox – Is It A Chicken Or An Egg”

Exchange 2010 OAB Recommended Configuration

Posted on by Rhoderick Milne [MSFT]

The Exchange 2010 OAB needs some love and attention after it has been created with the default settings.  While things may not be broken, they are less than ideal.

The Exchange OAB was last really overhauled with Exchange 2003 SP2 and Outlook 2003 SP2.  This was the move to the fourth generation of OAB and was done for many good reasons.  They included:

  • Ability to generate local specific indexes
  • New

The whoami command does exactly what you would expect, it tells you who you … Read the rest “Remote PowerShell – PSSession WhoAmI”

When To Move Arbitration Mailboxes

Posted on by Rhoderick Milne [MSFT]

The concept of arbitration mailboxes is not really new, they were first introduced in Exchange 2010.  Arbitration mailboxes are used for several special tasks within Exchange and for the most part will tick away quite happily with minimal administrator intervention.  System mailboxes have existed for much longer in Exchange, and again perform special tasks which are required by Exchange.
