Exchange 2010: Loadbalancing Relay Connector

/by

On an Exchange 2010 environment I needed to allow smtp relaying for specified hosts. The procedure for doing this is explained clearly in the Exchange 2010 documentation. So I created a relay connector on all servers with the HT role and since we are using Virtual Loadbalancing appliances from LoadBalancer.org to loadbalance the HT and […]

Exchange Move Mailbox Experiences Part 5

Another interesting Move Mailbox error and in this case I am really unsure how this would be possible!

The previous part (part 3) addressed Mailbox Size but did you know that even Message Size (or rather Item size) can prevent a successful move as well? Here’s an example move mailbox log: 2-10-2011 3:18:58 [The Exchange Server] A corrupted item was encountered during the move operation. The item wasn’t copied to the destination mailbox. […]

Exchange Move Mailbox Experiences Part 3

In Part 2 I showed some details about Mailbox Rule corruptions that can disturb Mailbox Moves. For this part the topic is Mailbox size, which can be an important factor in deciding which mailboxes you want to move first.

Inline arrays in PowerShell

/by

Sometimes I want to process a list of “things” easily in PowerShell where the list is not in an external file but in the script itself. Ideally this list would not be separated by e.g. a comma so it can be easily copy/pasted from external data sources. Something like this: $List = @(” John Doe […]

Exchange Move Mailbox Experiences Part 1

/by

I am currently working on a migration project from Exchange 2003 to Exchange 2010. Most Exchange migration projects use Mailbox Moves to move the mailbox data to the new Exchange environment. But there are some things I observed during Mailbox Moves (from Exchange 2003 to 2010) that are worth mentioning. Remko WeijnenWas once an enthusiastic […]
