This PowerShell script will give you a report of all of your Office 365 mailbox users who haven’t logged in for any given number of days. Once you’ve saved the script to a .ps1 file on your workstation or server, you can run it with just the script name or you can include the number of days inactive as a command-line option. the command-line option is especially […]
Yesterday there were a million and one web pages on Sender Policy Framework. Today there are a million and two. When I was researching SPF record syntax for some changes in my email routing, I couldn’t find a single page that gave all the information I needed. I hope this one will save you some time. Sender Policy Framework is a quick-and-dirty method for using […]
In the previous installments of this series on migrating distribution groups from Microsoft Exchange on-premises to Exchange Online, I covered these four steps: ► Part 1 – Overview of the process I used to migrate my Exchange distribution groups to Office 365. ► Part 2 – Exporting your on-premises distro group settings to CSV files. ► Part 3 – Importing your group settings from the […]
In steps 4 and 5 of part one I wrote, 4. Delete on-premises groups. After verifying that I had all the data I needed to rebuild them in the cloud (or on-premises if necessary), I removed the original groups… 5. Rename and address online groups. I wrote a third PowerShell script (Address_DistroGroup.ps1) that renames the new online groups to the old on-premises group names and […]

I used the list I created in step 1 to create corresponding groups in Exchange Online, appending ” OL” to the name of each group to avoid conflicts. This is easy enough to do using a formula in Excel to create the PowerShell […]

Gather data. I exported a list of all distribution groups and their properties to a csv file. Then I wrote a PowerShell script (Export_DistroGroup.ps1) to export key details to multiple csv files for each group, […]
I am most of the way through a hybrid-mode migration from Exchange 2010 to Office 365. There are a few stages in a hybrid migration. During the process, your on-premises Active Directory database and Exchange directories are synced to the cloud so that mailboxes that have been migrated still appear in the on-premises directory for mailboxes that have not migrated and vice versa. Distribution groups […]
