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
How to control O365 licensed products
I’ve had this conversation at least once a week for the past several months. Customers ask, how can they use PowerShell scripts to assign/control O365 licensing workloads assigned to end users? Don’t use a script, use Azure group-based licensing. The problem with a script is, you must assign all workloads, then remove the ones you
Can an Exchange DAG (2010 or higher) run on two different virtual platforms?
Yes, it would be supported.
