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 […]
In step 2 of part 1, I created online versions of all my on-premises distribution groups: 2. Create groups in Exchange Online. 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 […]
In part one (see here) I mentioned a PowerShell script (Export_DistroGroup.ps1) that I wrote to export certain settings of distribution groups in preparation for migrating them to Office 365. 1. 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 […]
I had a case recently in which the end user couldn’t add any resource calendars to Outlook. Every time she tried, she would get this error message: “The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.” Which was curious because the Outlook status bar said it was connected and she was able to send and receive emails.
It might seem a strange thing to want to do seeing as how distribution groups are traditionally used only for internal email distribution, but many organizations find that a distribution group is preferable to a shared mailbox for some applications. In order to allow a person or group to send email using the address of a distribution group, you need to grant Send As permissions […]
