Another wayĪnother way is to simply merge the leaver mailbox into the new joiner or other mailbox. * Kind of… If you add a mailbox using the additional account method you can use the slider bar, if you just add an Additional mailbox, you will get all the Secondary Mailbox data inside your own OST and it will use your slider settings. In Outlook additional Mailboxes don’t respect the Outlook slider bar either * (was all or nothing cached) – so a very large secondary mailbox could consume a large OST file on disk. Not massively hard, but another step, nonetheless.
In OWA they would need to know how to connect to an additional mailbox. That in itself entails a few issues because if it is hidden from the GAL then an end user can’t actually add it in Outlook. This method does of course mean that anyone wanting access to those old emails needs to be granted Access (usually Full Access) to the mailbox and connect it to their Outlook Profile as a separate mailbox. This Shared Mailbox can be hidden from the GAL and enabled with a permanent autoresponder and a forwarder. The Shared Mailbox can remain as a good resource for checking old email and as an entry in the Global Address List to still receive email. UPN, alias, email address etc whilst retaining the leaver information as a proxyAddresses.Īt the end of this blog, I am going to include a link to a Microsoft Consultant’s excellent blog and script regarding moving merging specific folders inside the same mailbox or cross mailbox – “Merge mailbox folders using EWS” Shared Mailbox Sometimes I have also seen the New Joiner simply inherit the old mailbox, and have a full end-to-end rename process for the Azure AD Account i.e. (Sometimes, but not very often these days, it is exported to a PST)
A common way of dealing with leavers is to simply convert their Mailbox to a Shared Mailbox and then terminate the user account. There are many reasons why you may want to do this but probably the most likely is the “Leaver” scenario.
