Pin virtual guests to specific physical hosts

This is a common discussion, who should be in charge of High Availability (HA), the host virtualization operating system or the application? If you ask an electrician how to fix something, they’ll tell you to rewire it. If you ask a carpenter what is wrong, they will say rebuild it. If you ask a virtualization

Where is OMA?

Some of you may ask, what is OMA? Back in the day, Exchange 2003, mobile devices were starting to make their way into the corporate world. Outlook Mobile Access (OMA) was introduced to help provide a small, thin foot print to mobile devices. You have to also remember that back in 2003, cellular networks were not what they are

Can an Exchange DAG (2010 or higher) run on two different virtual platforms?

Yes, it would be supported. Any supported virtualization product on this list is supported: https://www.windowsservercatalog.com/svvp.aspx From an Exchange perspective, it wouldn’t care what it rides on. You can mix and match all day long, as long as the Exchange versions are consistent. In fact, the Exchange role requirements calculator doesn’t even care about virtualization, the

Security breach by known bad actor group

Another scary post on Halloween. Scary that is, if you're not following security best practices. This bad actor group exposes a timing issue with O365 safe links. They create a certificate for a site, that looks ligament, and then exploit it as quickly as they can. For example: Securemail.contoso.com. Since the cert is valid and

Will Jetstress be updated for Exchange Server 2019?

Yes.  However, the PG chose not to extend Jetstress functionality to cover MCDB (on Flash/SSD storage), therefore, Jetstress will only validate HDD performance for Exchange Server 2019. What is JetStress? The JetStress tool (download) is a Microsoft supported tool that validates database hard drive performance before you install the Exchange Server application on a Windows

We're updating the article to include solutions to fix the problem. This post is

Get-DAGDatabaseInformation

The function: Get-DAGDatabaseInformation works in Exchange versions that a DAG (Database Availability Group) exists. From 2010 through 2019, this simple little function presents information to the end user about the status of the databases.
