Up until recently, the process to get a relaxed throttling limit during an O365 onboarding migration, was to open a Microsoft Support case. This process is now available as a self-service option. During an O365/M365 data migration, there are several performance best practices to follow. But even after following the guidelines, sometimes the cloud service

Mark Nivens created this HealthChecker.ps1 file for Exchange servers for your on premises environment. This script checks various configuration items on the Exchange server to make sure they match the recommendations published in the "Exchange 2013 Sizing and Configuration Recommendations" guidance on TechNet. It also reports on Operating System and hardware information. You can run it remotely against a single

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

The function: Get-DAGDatabaseInformation works in Exchange versions that a DAG (Database Availability Group) exists.

This site talks about limits, but it also depends on what is available vs. what you can support. By running some PowerShell code, the answers can be provided: Get-ReceiveConnector  | Set-ReceiveConnector -MaxMessageSize

Thought this would be a good Labor Day discussion, about how much labor an Exchange administrator performs. The short answer is, you’ll still be very needed if/when your company decides to move to Exchange online in O365. So you think you’ll lose your job when your company moves Exchange on premises content into O365 using

Need to know a member count of ALL distribution groups and e-mail enabled security groups in your organization that exports to a CSV file? Then this function is for you. 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,

These two are really good functions. While I just used others’ code, I do give them credit, but to be able to ‘function these up’ is very handy. Not that I’m lazy…OK, I’m efficient, but having verb-noun at your fingertips, whenever you need to run something, is very convenient. Furthermore, I can’t tell you how

This Connect-ExchangeServer function runs the PowerShell code to log into an Exchange server on premises using remote PowerShell. Using the -Computer parameter (required), tells the function which Exchange server to connect to.
