Reduce Exchange 2016 Mailbox Database White Space

Reduce Exchange 2016 Mailbox Database size using Eseutil. In this post I will walk through the steps of reducing the Exchange Mailbox Database size, However the method of reducing the Mailbox Database size varies from different administrators. If you can afford to have downtime on a Mailbox Database then these steps would work for you. Some Exchange Administrators  and in most cases myself ,will simply just create another new Mailbox Database and Move Mailboxes from one Database to another and then delete the old one. For the purpose of this post , I will be using a build in tool from Microsoft called Eseutil.   Eseutil is a command line utility that works with Extensible Storage Engine (ESE), database (.edb) files, streaming (.stm) files, and log (.log) files associated with an Information Store, in a given Storage Group.

DKIM on Exchange

Setting up DKIM for Exchange Server for DMARC

Setting up DKIM for Exchange Server Out of the box Exchange Server does not support DKIM signing. And it doesn’t look like Microsoft has any intention of adding this feature any time soon. So for now the best way to implement DKIM signing is via third party a plugin. What is DKIM? DKIM (DomainKeys Identified Mail) is an email security standard designed to make sure messages weren’t altered in transit between the sending and recipient servers. It uses public-key cryptography to sign email with a private key as it leaves a sending server. Recipient servers can then use a public key published to a domain’s DNS to verify the source of the message, and that the body of the message hasn’t changed during transit. Once the hash made with the private key is verified with the public key by the recipient server, the message passes DKIM and is considered authentic.… Read More »Setting up DKIM for Exchange Server for DMARC
