Everyone has access to all mailboxes!

[DotNetNewbie]

Hi,

We recently migrated to Exchange 2010, everything seemed to be working fine until a user reported that he could access another user mailbox.

Having done a search on the internet I noticed that each user seems to have a lot of additional permissions. I have removed all the groups that have "Full control", however users are still able to access each others mailboxes.

Any ideas most welcome

get-mailboxpermissions | fl and see who has access to what.

I've seen the Everyone group in Domain Admins so this is a good start... ;-)

Zelandakh - thanks for taking the time to reply.

I managed to resolve it yesterday but didnt get around to posting. Oddly it was "Domain Users" that had been added to "Domain Exchange Servers" - not sure when or how that had been done, but removing it, waiting 2 hours, getting the clients to reboot resolved the issue.

The cmdlet you mentioned was also useful, I came across this when looking on the internet.

Thanks again.
