Get-GroupMemberCount This function simply creates a .CSV file of all the e-mail enabled groups and current member count. May not be the most elaborate task,

Here are some handy short links that help Exchange Server engineers keep up with what's happening within the Exchange world. As always, it's best to have some kind of RSS feed notification, using tools such as: Microsoft Flow or IFTTT.com. The Exchange Team blog, you Had Me at EHLO: aka.ms/ehlo Exchange Server build numbers and

I’d like to introduce you to my MO_Module. It’s a PowerShell module, combining several daily administrative tasks into simple Verb-Noun Functions for engineers to perform their jobs easier.
