Hi,
We have Microsoft Exchange running on a Network with 50 or so users.
One user has said they are able to view other peoples mail.
They should not have permission to do this.  
I have looked at this user and they are not a Member of any Administrators Group.
Nothing else seems out of place either.
Is there anything obvious I am missing?

Is that the Mailbox Rights under the Exchanged Advanced Tab?
In for all users it has
Domain Admins
Everyone  - Under the Allow option Read Permissions and Full Mailbox Access are ticked but Greyed out. Is this it?

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

In ADS ADUC console >Exchnage tasks > Exchange Advanced > Mailbox Rights .Also everyone should have read permission only
If anything else is selected remove all just for 1 user.
Test before you do to all users...
Give it some time to replicate...

In the Exchange System Manager, I have went to the Mailbox Store and Properties and the security Tab, in there, Everyone has no permissions.

In the ADUC Everyone has Read Permissions and Full Mailbox Access ticked but greyed out.
Will I check the box for deny beside the Full Mailbox Access?

Try to remove the users permission in ADUC for 1 user and see what happens...

File > Open Other Users Folder

Download Active Administrator from
http://www.scriptlogic.com/
See each OU's delegation...This will show if the particular user has full permissions on the OU

I had left it with the Deny box ticked beside Full Mailbox Access, it seemed to take a couple of hours for the permissions to take effect.  But once they did the user was unable to open there own mailbox.
