Regarding exporting the mail, it was as catalandres said - no direct way to export the mail out of the group. I started off by creating a placeholder user for the account. I seem to have succeeded in getting the group changed over to a regular mailbox, using Outlook 2016, Office365 Admin and Exchange Admin. can anyone suggest whether this plan needs some work or is likely to succeed, or if I'm on the right track but need to add/modify items etc.? Give the previous group users permissions on the new mailbox, then make sure their accounts are all picking it up and they can send as the mailbox.Import the previously exported pst file into the Inbox.Create a new mailbox user with the previous group mailbox address.Rename the mailbox to something else and make sure any alias addresses are removed. In Exchange, remove the users of the group.export the contents of the O365 Group mailbox into a.

So my plan for conversion goes something like so: They need to retain the email address as active because it is listed in external software and websites etc.

I haven't played around with O365 Groups before and so far my limited exposure to them is that they are indeed completely not the correct solution for the customer. The customer wants to convert the mailbox back to a regular mailbox that the users share instead, as most of the functionality they are familiar with isn't available in the O365 Group. Remove the alias by selecting the remove icon, and then select Save and Close.One of our customers who is on Hosted Exchange has a few Office365 Groups defined, the largest one is only 4 users. On the Active users page, choose the user. Sign in with your Office 365 admin account. You must have admin permissions in Office 365 to do this. When Ina replies to the message, her primary email address will appear as the sender, not an alias from a user For example, let's say a message is sent to and it arrives in Ina's inbox. When the user replies, the From address will be her primary email alias. All mail sent to and will go to Sally's Inbox. The user now has a primary address and an alias. Wait 24 hours for the new aliases to populate throughout Office 365. To add another domain name to the list, see Adding additional domains to Office 365. Note: The email alias must end with a domain from the drop-down list.
