I have an pure Exchange 2007 environment, migrated before my time from Exchange 2003 and there is no Exchange 2003 in the company any more.I am trying to migrate the legacy "shared mailboxes" to Exchange 2007 real Shared mailboxes with the rights assigned over a group (before the rights were assigned directly to users)In the Exchange Management Console,"Manage Full Access Permission" Wizard, I have a few users with a question mark next to their logo. I couldn't find out what it means but I suppose it is linked to my problem. When I try to remove these users from the mailbox I get following message:Summary: 1 item(s). 0 succeeded, 1 failed.

Hey !The solution that works for me:- Installing the Exchange 2003 Management Tool (incl. AdminPack and IIS)- Right click -> Properties -> Exchange Advanced -> Remove 12 SID's and the User(s) with "Full access"My Problem now:There are 12 SID's on every mailbox, which are NOT inherited, and the only chance for me to remove them is clicking on +-1000 user accounts...Is there an easier way ?Thanks

Hello Phets,You should be able to remove all unresolved SIDs using ADFIND in bulk. Please refer http://social.technet.microsoft.com/Forums/en-US/winserverDS/thread/f389b0eb-8095-48d6-a004-c63487aa7499for further examples and reading.Milind Naphade | MCTS:M | http://www.msexchangegeek.com

Hey Milind Naphade !Sorry but the link you provided couldn't help me.... I think if I start now beside searching for a "bulk Edit" i will have it finished earlier ;)

Hey,There are some cool tools available from WiseSoft on internet. You can check fromt their range if they can help.. http://www.petri.co.il/password-control-bulk-modify-for-active-directory-windows-server-2008.htmPersonally, ADFIND should work in your case though. The only trouble you will have to go through is running it more than once.Milind Naphade | MCTS:M | http://www.msexchangegeek.com
