Hello, I have a shared Exchange 2007 mailbox which around 20 users have access to. However I have noticed that virtually everyone can access this. I have checked the permissions via EMC and cannot see how they are getting access. I also checked delegate access on the Outlook client but nothing. How can I see how the users are getting access ? Thanks Bill

Please check the manage send as and full access permission of shared mailboxRegards, Prabhat Nigam XHG and AD Architect and DR Expert Website: msexchangeguru.com VBC: https://www.mcpvirtualbusinesscard.com/VBCServer/wizkid/card

You need to check you have granted everyone or some other group if they have receive as rights on the database, server level, org level etc and remove it. You can use adsiedit and work your way up from the database level, properties, security tab. James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi Bill, When you create one new mailbox, will this issue occur or not? If this issue also occur on new created mailbox, you can follow James's suggestion to check on the database, server or org level. If this issue not occur on new created mailbox, please run these commands and post the results: Get-mailboxpermission -identity usermailbox|fl Get-Adpermission -identity usermailbox|fl Thanks, Evan Liu TechNet Subscriber Support in forum If you have any feedback on our support, please contact tnmff@microsoft.com Evan Liu TechNet Community Support
