  • Exchange Mailbox Migration From 2003 to 2010

    When i try to migrate mailboxes from exchange 2003 to exchange 2010 i get this error on all users.
    Active Directory operation failedon <domain> This error is not retriable. Additional information: The attribute value cannot be removed because it is not present on the object. Active Directory response: 00002085: ATrErrrSID-031521b#,#1:0: 00002085: DSID-031521B3, problem 1001 (No_Attribute_or_Val), data 0, Att 200d2 (proxyaddresses): len 94
    I tried checking the proxyaddresses attributes , rebuilding Recipient Update Services, The Security inheritance on the end user object. Any help would be appreciated

    Can you give us more information on your setup and what steps have been carried out so far. For example, how many domains, version, service pack level of DCs, ADPREP peformed, number of sites etc, Exchange 2003 level and have you done a DCDIAG prior to ADPREP?

      What method are you using?

      If it's feasible, exmerge everything under 4gb, and make a local pst of everything over that. Tell everyone to clean out their inbox, delete junk mail, deleted items, etc.
