Outlook unable to connect to Exchange 2010

  Recently, I was doing a simple Exchange migration from Exchange 2007 to Exchange 2010.  Once I moved all the mailboxes to the new exchange server, we noticed issues with Outlook.  The version of Outlook was 2003. These were the issues being reported: Random Outlook freezing and locking Error – “Your Exchange Server administrator has blocked the version of Outlook that you are using. Contact your administrator for assistance.” Error – “Cannot start Microsoft Office Outlook. Unable to open the Outlook window. The set of folders could not be opened.”[…]

Exchange 2010 and Outlook 2003 Slowness

It’s been a little while since I have had to migrate Exchange 2003 to 2010, and I ran into a familiar problem again – so I thought I would share. I migrated a couple users over from the Exchange 2003 server onto the Exchange 2010 server, and the next day users were complaining of slowness.  It would take about 30 seconds or more for messages to be deleted, moved, and any sort of update to the mailbox.  It doesn’t seem like much, but when you are upgrading, and the new[…]

Exchange 2010 Distribution Group Management

One of the things I like about Exchange distribution groups is that they can be manged by the list’s owner, taking a bit of work off the IT department, and allowing managers to maintain their department groups.  However, the process is slightly different for Exchange 2010.  In Exchange 2010, the permission to manage the lists is now in RBAC (Role Based Access Control). By default, in Exchange 2010, users cannot manage distribution lists (a good thing).  Enabling them to do so is a simple task.  We use the MyDistributionGroups management[…]

What is AdminSDHolder?

AdminSDHolder is a container inside active directory that maintains a master list of permissions for objects that are members of privileged groups in active directory.  Below are some of the groups: Administrators Domain Admins Enterprise Admins Schema Admins Domain Controllers Server Operators etc. Basically, every hour, windows will compare the security permissions of an account (that is a member of a privileged group) to the permissions listed on the AdminSDHolder object, and if they are different, reset them.  The AdminSDHolder object is in Active Directory under “System” (you will have[…]

Public Folders not replicating from Exchange 2007 to 2010

I’ve been working on an exchange migration recently, and was at the point that I needed to replicate the public folders to the new 2010 server from 2007.  This particular Exchange Server had only a few public folders, so I went the manual route. On the Exchange 2007 Server, I opened up Public Folder Management Console from the toolbox, and right clicked on each folder, chose properties, and edited the replication tab entry. What I noticed, is that when I went to the Public Folder Management Console on the Exchange[…]
