It is one of these weird circumstances when a single user has one AD account but is attached to two mailboxes – one mailbox is in Office 365 and the second one is on on premises Exchange essentially, it will be connected to on premises via Autodiscover. This condition is terribly akin to the one defined in the second scenario above, with the one difference that an Office 365 user has the Office 365 license assigned adding a license for Exchange Online. As you can imagine having two mailboxes in hybrid settings causes problems in email flow for that user. When the MX record points to Office 365, an email will get stuck in Office 365 mailbox and could not be delivered to an on premises mailbox. Hi – I have a state of affairs and searching for help I have users who have an AD account and who even have a contact account in an analogous AD domain – So both type of accounts using same email tackle, which is external to the AD domain as a result of these users are form of contractors who use their parent company mail address.
Both are synced to AAD – for the AAD sync because the contact account is synced after the user account, it merges with the user account and no sync errors pop up. But the emails send to those mail address sourced from any on prem mail boxes are getting dropped at trade server showing duplicate accounts found with same email. We have a hybrid environment and this is inflicting a real messaging issue for all users. Any guidelines please?– Thanks in AdvanceAnd I did follow these steps : —— Connect to an Office 365 tenant using Azure Active Directory Module for Windows PowerShell: Connect MsolService Then, remove the user by executing the following cmdlets: Remove MsolUser UserPrincipalName j. Remove MsolUser UserPrincipalName j.
RemoveFromRecycleBin Finally, recreate a user via Azure AD Connect by forcing the synchronization manner run the cmdlet on the server with Azure AD Connect: Start ADSyncSyncCycle PolicyType Delta As soon as you spark off the Office 365 license, make sure to see here suggestions: — Hi Alfred, Glad you found the article useful!The scenario you need to follow is the first option in the object, so yes, the proxyAddress matching. You can create the users by hand since there is only 15 of them; though, I’d automatize it with PowerShell. But first things first: AAD Connect is basically used to sync on prem Exchange to Exchange Online. If I bear in mind as it should be, AD attributes aren’t synced from the cloud to the on site Directory. That’s why I would first create a test account in O365, define some attributes, sync using proxyAddress matching and spot what occurs.
Which, I suspect, could be syncing the empty, characteristic less account to the cloud. After that, the synchronization should go with none headaches. Hello Radamel, That is difficult. Azure AD Connect does not allow a sync from the cloud to the on premises environment. So if you want to export users from Azure AD into the local AD, you would ought to do it with PowerShell cmdlets.
Mind that there’s no PowerShell script to export passwords, so you are going to need to create temporary passwords to your target AD atmosphere. I presume that you will even have to migrate mailboxes?To migrate them, I would use CodeTwo Exchange Migration. This program will create users in the objective environment for you and migrate mailboxes from Office 365 to the on premises Exchange in a good way. Hi Adam, great article, thanks a lot!I work in a university as teacher and have a further function there as admin of our local AD home windows Server 2012 R2 and our Office 365. Our setup is like this: Until many years ago we had a Windows Server 2003 in the school with AD and Exchange.
While the server still worked as AD, we moved our mail to Office 365 and I created users with mailboxes in Office 365. Later when got a new Windows 2012 R2 server for AD, it didn’t synch from the Office 365 to our local server, only the other way round, inspite of Azure likely because I don’t know the way to do it. So I had to create users in AD, and they are instantly synched with Office 365. I do that with new lecturers and it works fine. But I would like to merge the “old” academics in our system to circumvent the synch conflicts from Azure. Since we also use onedrive and sharepoint, I’m a little reluctant to alter anyhthing that I don’t know the consequenses of.
But along with your guide I hope to end up with only one account for both the old and new users.
