Using New Outlook on Windows for professional communication and productivity
Thank you for reaching out to Microsoft Q&A Forum.
Microsoft released an update for the new Outlook for Windows (as part of Microsoft 365) - Microsoft 365 Roadmap | Microsoft 365, that will allow users to seamlessly move emails between different accounts. This functionality will be controlled via IT policy settings, giving administrators granular control through Exchange PowerShell.
More information about this can be found via this article: Supported accounts in new Outlook for Windows | Microsoft Learn
To enable this capability, a new parameter has been introduced: ItemsToOtherAccountsEnabled within the Set-OWAMailboxPolicy cmdlet. By configuring this setting, administrators can permit users to move emails between accounts in accordance with organizational requirements and compliance standards.
Since enabling this feature requires administrative privileges, I recommend reaching out to your organization's IT administrator for assistance. For more details, please refer to the official Microsoft documentation on this cmdlet here: Set-OwaMailboxPolicy (ExchangePowerShell) | Microsoft Learn
To run commands like:
Set-OwaMailboxPolicy -Identity <PolicyName> -ItemsToOtherAccountsEnabled $true
You need to connect to Exchange Online PowerShell first.
Step 1: Open PowerShell as Administrator
- Click Start
- Type PowerShell
- Right‑click Windows PowerShell > Run as administrator
Step 2: Install Exchange Online Module (only once)
If you have not installed it before:
Install-Module ExchangeOnlineManagement
If prompted, choose Yes to All.
Step 3: Connect to Exchange Online
Run:
Connect-ExchangeOnline
Sign in with your Microsoft 365 admin account.
Step 4: Run the Command
Once connected, you can run:
Get-OwaMailboxPolicy
Identify the policy name, then enable the setting:
Set-OwaMailboxPolicy -Identity "<PolicyName>" -ItemsToOtherAccountsEnabled $true
Repeat for any policy used by the source and destination mailboxes.
