In my exchange server 2013, I can see multiple security groups under Full permission /delegation option.
I have 1000+ employee users to whom I would like to have Full access being on service desk side.
The groups that already appear are Exchange Full admin, Exchange admins, Exchange Services etc ..
Recently , my admin account has been added to all these groups. However, I cannot access any one account from webmail and I get following error :
something went wrong
You don't have permission to open this mailbox.
X-ClientId: TSLB - OQEM - PXSA - H0LMA
Date: 6/14/2015 2:36:36 PM
However, If i manually add my admin account under any one mailbox as Full permission, then I can view his mailbox.
I have following questions :
Adding my admin account to 1000+ manually will not be the right way in order to manage those mailboxes. Since I am already part of those security groups , why I am unable to access mailbox ? When we have exchange 2010 , it used to work.
From where Exchange ECP is picking up those security groups and some other user account like backup etc ? I mean where we can define the list of Groups and Users that should be part of all Mailboxes and appear under Full permission by default.
Last, How can I fix the issue ?
