In preparation for a migration to Office 365 Exchange Online, I need to ensure Outlook Web Access is working for all users on the current on-prem SBS 2003 Exchange configuration.<br />
It wasn't configured at all and I've since run the Internet connection and Email wizard to enable Outlook Web Access and for a newly created user in the SBS Users in AD, <a href="https://ourdomain.com/exchange" rel="ugc">https://ourdomain.com/exchange</a>&nbsp;is working fine. &nbsp;The user can log in without issue.<br />
But for all existing users, it just keeps prompting for the username and password.<br />
I've found that it is because the users do not have the &quot;Associated external account&quot; set to Allow for the user &quot;SELF&quot; in Mailbox Rights for these accounts.<br />
I can enable it, but considering there's over 30 users, I was hoping there was a quick way to change it for all users.<br />
<br />
Is there any way this can be done?

apply Mailbox Rights permissions for multiple users at once

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
