On-premises user isn’t receiving emails from online user

On-premises user isn’t receiving emails from online user


First we must move the user to un synced OU

The log in the the server which have the Azure AD sync tool

And open the windows azure active directory tool

Now that we have moved the user in a unsynchronized OU and that it’s appearing in the “Deleted users” section, you have to forcefully delete the user so you won’t have to wait for 30 days:

Run the following command

In the azure power shell

Start-ADSyncSyncCycle -PolicyType Delta

Then open the PowerShell and connect to the online exchange

Use the following command

Import-Module MSOnline

$O365Cred = Get-Credential

$O365Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $O365Cred -Authentication Basic -AllowRedirection

Import-PSSession $O365Session

Connect-MsolService -Credential $O365Cred

Then run the following to get the object ID

Get-MsolUser -ReturnDeletedUsers | FL -Property ObjectId,displayname

We must get the user objectID

Remove-MsolUser -ObjectId 080535c0-061a-4b0e-a6fe-48ed7fc9159d -RemoveFromRecycleBin -Force    

Note: make sure you enter the correct ObjectId

After deleting the user, you will have to make sure his cloud mailbox is also deleted using one of the following cmdlets:

Get-Mailbox -Identity “username@domain.com | Remove-Mailbox -PermantentlyDelete $true

Get-Mailbox -SoftDeletedMailbox “ username@domain.com ” | Remove-Mailbox -PermantentlyDelete $true

Now do another delta sync in the azure AD server

Start-ADSyncSyncCycle -PolicyType Delta

After the cloud user and cloud mailbox are completely removed from the tenant, move the user from your local AD back into the synchronized OU, do a Delta Sync and then wait for the user to appear again in the Office 365 cloud, under Active users. Do not assign a license to the user.

Now move him back to the synced OU

And run the command

Start-ADSyncSyncCycle -PolicyType Delta
