Exchange 2010 distribution group RRS feed

  • Question

  • I've read that when migrating to exchange 2010, convert groups to Mail universal groups.
    I've also read that I should properties on the distribution group, add a letter to the name of the group, remove
    the letter, hit apply and exchange 2010 will prompt me to upgrade the group.
    What does this 2nd step do?
    Is there a powershell command  I can run to determine which groups need to be converted to 2010 format? Will exchange 2003 clients still be able to send emails to such 2010 distribution groups?

  • all mail enabled groups must be universal in 2007/2010.

    2003 can still use these.

    Dont worry which ones need upgrading, upgrade all of them - http://social.technet.microsoft.com/Forums/eu/exchange2010/thread/3e0f54e4-2f7a-47d2-9f33-9bec1d9c128b

    the letter thing is to upgrade the group.

    "The ForceUpgrade parameter suppresses the following confirmation: "To save changes on object <object name>, the object must be upgraded to the current Exchange version. After the upgrade, this object can't be managed by an earlier version of the Exchange Management Tools. Do you want to continue to upgrade and save the object?" This confirmation occurs when you upgrade a distribution group that was created in Microsoft Exchange Server 2003. You can't manage an Exchange 2003 distribution group by using the Exchange Management Console until you update the object's version."
