Creating New user - default exchange database is using the recovery database

Posted on 2007-08-09

Hi All,

Very strange problem, in that when I create a new user via the SBS Wizard it creates the users  mailbox in the recovery database.

This was used a while back to retrieve an inbox.

The problem arises once you try and use Outlook, it bombs out.

If in AD we remove the exchange attributes from the user and then create a new mailbox it places the mailbox in the correct database.

Very odd why its picking the recovery db as a default.

Any ideas would be great.

    To begin with the RSG database shouldn't be left in place all the time. Once you have used it the database should be dropped.

    The databases are listed alphabetically, so it is probably the first in the list.

    Thanks Sembee,

    Its not first in the list but it is there, the order

      First Storage Group
      Recovery Storage Group

    If I right click the recovery storage group it gives me an option to delete it, have I understood correctly it puts it there to allow a transfer of mailbox to the main database and after should be deleted?

    The RSG should be created when required. If you are not doing a restore then drop it.
    If you run the Exchange best practises tool it will tell you the same thing.

    This is getting odder, I am unable to delete the recovery store as even though it is dismounted it reports as in use and should move the mailbox across.

    If I mount it I can see the user that had the mailbox merged back into the First Storage Group, interesting all the other users have the red x apart from this user, but there is no options other than to merge or copy. Worried if I copy it will over write current email.

    Can't seem to find a way to disable the mailbox in the recovery store.

    What has probably happened is that accounts have been created in that store. You need to do a move mailbox to change them to the correct store. Move mailbox is in ADUC.

    You may have other accounts that are also referencing that store. Search for them in ADUC using the technique I have outlined at the end of my migration article here:

    Hi Sembee,
    That's spot on, using your doc I was able to find which accounts were using the recovery DB - (2 test accounts) deleted these and could then delete the recovery DB and now new users are picking up the correct DB.

    Many thanks for your help.

    Issue is resolved.
