I had a user that was temporarily gone. &nbsp;His mailbox was never deleted and his AD account was never disabled or deleted. &nbsp;I did, nowever, in his Mailbox Properties within Exchange console check the &quot;Hide from Exchange address lists&quot;, which did hide it. &nbsp;He has now returned and I have unchecked the &quot;Hide from Exchange address lists&quot; and after 30 mins his information still isn't in the address lists. &nbsp;Does anyone know the &quot;amount of time&quot; for the change to take effect and make &nbsp;him visible again? &nbsp;Is there a PowerShell function I can use to expedite this process?

I had a user that was temporarily gone.  His mailbox was never deleted and his AD account was never disabled or deleted.  I did, nowever, in his Mailbox Properties within Exchange console check the "Hide from Exchange address lists", which did hide it.  He has now returned and I have unchecked the "Hide from Exchange address lists" and after 30 mins his information still isn't in the address lists.  Does anyone know the "amount of time" for the change to take effect and make  him visible again?  Is there a PowerShell function I can use to expedite this process?

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.
