E-mail addresses and aliases gone RRS feed

  • Question

  • Posting here to find out if anybody else had a similiar experience and also getting some idea on where to start with this.

    At one of our sites, which is a domain part of a Forest, we had our e-mail address and e-mail aliases disapear from only selected people. Only way to fix this was to re-add the e-mail addresses and alias manually but the mailboxes where still in tact.

    I suspect it was with the forest upgrade to 2008 but it does not make sense only a few users in the subdomain is being effected in the above described way. Throughout the forest we using Exchange 2007 and the administrator of the root forest says he can see the e-mail addresses and aliases but from our domain we could not.

    If my understanding is correct this could not have been the case of a forest upgrade to 2008 as then all of the user accounts should be effected? Furthermore is there any other tools besides repadmin, dcdiag, windows event log one can troubleshoot these type of isses?

  • Was there anything in common with these users, by any chance? For example, did they have any security entries applied to their accounts that in turn related to the Exchange default role-based groups?

    I can't put my finger on why, but it feels like a permissions issues perhaps involving the Organization Management / Exchange Organization Administrators side of things, and possibly the time taken to replicate the schema changes.

    Sorry that I'm only speculating, but I haven't seen this issue before myself. You might also like to try asking in the Exchange forum.

    Cheers,

  • Thanks for the reply - is there any way to see historical information on replication and in specific schema changes? repadmin is great but does not seem to really catter for historical information.

  • Not really, no. The schema updates go generate their own logs, but I don't think those are going to be worth investigating, as this isn't going to relate to the schema changes, per se.

    There's is also a log for the forest and domain preparation, but for the life of me I can't remember where it's saved off the top of my head. Perhaps %windir%\temp at a guess.

    Cheers,

  • Hello,

    the log files are stored in %Systemroot%\system32\debug\adprep\ogs directory

    Personal i did not see any missing entires when migrating/upgrading systems where Exchange is installed.

  • If you still have any of the users with missing email, you can use repadmin /showobjmeta to identify the domain controller where the change to proxyAddresses attribute originated. Check the time of the update - and see if you can find something that corresponds to that change in the logs

  • Thanks - had a look and that path is not included on any of the DCs. The forest upgrade was done by the Headquarters administrators so we do not have any administrative access to it. Aside that I am still going through logs but aside the normal warnings I cannot see anything else.

    Hello,

    then you mostly will find the log on the root DCs where the admins run the adprep command. The logs are only on the DC where the update is run as all changes are replicated to the other DCs as if you create new objects in AD.

    Maybe you should check the DCs in the site the users belong to if replication is working correct. Was there a kind of crash or someone had deleted some objects accidently somewhere in the time so they where restored but not complete?

  • I don’t believe this issue is related to ADPREP or upgrade. 

    >>> aliases disapear from only selected people. 

    What do you mean by select people?  Are they in a single OU or part of same group?

    Do they have mailbox or just mail enabled users?

  • we had our e-mail address and e-mail aliases disapear

    Just to be clear, the addresses you're speaking of, are they actual default addresses generated by your email address policy, or were they manually added in addition to the generated addresses? If manually created, then they are proxyaddresses and may conflict with the email address policies?

    Did you run what Marcin suggested to find the originating DC for the proxyAddress attribute? If you did, maybe I missed your reply?

    Are you seeing any Event ID 9514 on the Exchange servers? If so:

    Removing duplicate and unwanted proxy addresses in Exchange
    http://support.microsoft.com/kb/318774

    .

    Also, if this is occuring in a domain where Exchange is not installed, have you run the Exchange domainprep? You can re-run this to straighten out anything if there are any issues, not saying it will straighten this out, depending on this issue's cause.

    Since this is appearing more to be an Exchange configuration issue, as Lain and others have suggested, I think it's prudent in posting it in the Exchange forum.

  • Hi


    I dont think preparing the forest by running adprep will have such impact.

    This may happens if we have imported users using ldifde or csvde and that file does not have UPN or some other attribute as in your case then users might get created without email address or any other attribute.

    Did any admins or you  did an export to ldifde and then re-import or any migration is going on?
