VMware Issues With Exchange DAG

Posted on 21st July 2014 by Rhoderick Milne [MSFT]

When resolving issues with on-premises Exchange sometimes the issue may be directly within Exchange, other times the root cause may lie outside Exchange.

Exchange Scripting Agent – The Power Of Script

Posted on 24th June 2014 by Rhoderick Milne [MSFT]

Exchange 2010 introduced a very interesting feature – the Scripting Agent.

Posted on 17th June 2014 by Rhoderick Milne [MSFT]

The blog post on how to integrate Office 365 with Windows 2012 R2 AD FS raised an interesting question from a reader (Hi Eric!) on how should he request a certificate for the AD FS instance since there is no longer an IIS dependency. This means that there is no longer an IIS console to generate a certificate request with. What to do?
