How to create Exchange Online mailboxes for existing Active Directory user accounts in a hybrid environment
- Create account in Active Directory if it doesn’t already exist. Assign a routable UPN suffix.
- Force DirSync and wait for it to complete
- Confirm account appears in Microsoft Online Portal (MOP)
- Open Exchange Management Shell (EMS)
-
Run the following command in EMS:
Enable-RemoteMailbox {User_Name} -alias {Alias_Name} -RemoteRoutingAddress {Alias_Name}@{Tenant_Name}.mail.onmicrosoft.comFor example:
Enable-RemoteMailbox 365test1 -alias 365test1 -RemoteRoutingAddress 365test1@exitcodezero.mail.onmicrosoft.com
Use quotes to enclose any value containing spaces. For example:
Enable-RemoteMailbox "365 test2" -alias 365test2 -RemoteRoutingAddress 365test2@exitcodezero.mail.onmicrosoft.com
- Force DirSync and wait for it to complete
- Open Exchange Management Console (EMC)
- Confirm Remote User Mailbox exists in ‘Microsoft Exchange On-Premises’ organization
- Confirm User Mailbox exists in ‘Exchange Online’ organization. If not, force DirSync again and wait for it to complete
- Assign MSOL license
Hello – How could this be done by pulling 10 names at a time from a CSV file?
Thank you!!
$Users = Import-csv C:\Temp\EnableRemoteMailbox.csv
$Users | ForEach-Object {Enable-RemoteMailbox -identity $_.userprincipalname -RemoteRoutingAddress ($_.samaccountname+’@TENANT.mail.onmicrosoft.com’)}
