Completing an Exchange Online Hybrid individual MoveRequest for a mailbox in a migration batch

29th of November, 2016 / / 14 Comments

I can’t remember for certain, however, I would say since at least Exchange Server 2010 Hybrid, there was always the ability to complete a MoveRequest from on-premises to Exchange Online manually (via PowerShell) for a mailbox that was a within a migration batch. It’s really important for all customers to have this feature and something I have used on every enterprise migration to Exchange Online.

What are we trying to achive here?

With enterprise customers and the potential for thousands of mailboxes to move from on-premises to Exchange Online, business analyst’s get their “kind in a candy store” on and sift through data to come up with relationships between mailboxes so these mailboxes can be grouped together in migration batches for synchronised cutovers.… [Keep reading] “Completing an Exchange Online Hybrid individual MoveRequest for a mailbox in a migration batch”

WPAD and Proxy Auth Cause Exchange HCW to Fail

4th of May, 2016 / / No Comments

A recent conversation with a colleague reminded me of an issue I’ve faced a number of times (and forgotten to blog about) when running the Exchange Hybrid Configuration Wizard (HCW) on Exchange 2010 or 2013 in an environment where Web Proxy Autodiscovery Protocol (WPAD) is used.

The Problem

The most common scenario where I’ve seen this come into play is along the lines of this:

  1. WPAD is used to distribute Proxy.PAC to client machines
  2. Customer permits direct connection from Exchange servers to Internet
  3. From an elevated command prompt, run “netsh winhttp reset proxy” to ensure a direct connection
  4. Change Internet Options settings from “Automatically detect settings” to “Disabled”
  5. Browse to a site restricted by the proxy to confirm proxy bypass is working
  6. Can connect to Exchange Online using Remote PowerShell
  7. Run the HCW but it fails with the following error in the logs:
    ERROR : System.Management.Automation.RemoteException:

Hybrid Exchange 2007/2013 and Lync EWS Integration

14th of May, 2014 / / 1 Comment

I came across an interesting issue recently with a client currently running Exchange 2007 and looking to migrate to Exchange Online. Since Update Rollup 10 for Exchange 2007 Service Pack 3, it has become possible to coexist Exchange 2oo7 and Exchange 2013.

After installing Exchange 2013 as the Hybrid server, this particular client ran into an issue with the Lync 2013 client losing EWS integration with any mailboxes that still reside on Exchange 2007. The net effect of this is that any users that hadn’t been migrated from Exchange 2007 to Exchange 2013 or Office 365 would have to rely on Outlook MAPI (and Outlook being open) for anything to do with the Personal Information Manager feature of Lync.… [Keep reading] “Hybrid Exchange 2007/2013 and Lync EWS Integration”
