Full access with mail enabled security group access denied
Deleted What about granting full access to a single user account. Does this work? --> It does.
similar cases which pointed in the direction of a corrupt database. --> could you help me with cheking an online database itegrity? Or how should I check it? we have only one.
I am using the /g switch to check the db (which is in use).
Probably this is the root cause, I am getting Jet error 1032, JET_errFileAccessDenied, can not acces file is locked or in use. How should I proceed?
- Before creating another DB I would try to repeat the steps using just web GUI. Open ECP, go to Group tab and create another security group. Click + symbol and choose Security Group. Is the group created, go to Mailboxes tab (or Shared in case the target mailbox is shared) , find the mailbox you want to grant access to, open it's properties and choose Mailbox Delegation. Scroll down to Full Access and add this newly created group. Add yourself to the group and after a couple of minutes try to open the mailbox in OWA.
I am sure that you probable already know all these simple steps, but I would give a try. 
You probably will create a new database, move all mailboxes to the new one and see, if this fixes the issue. A mailbox move often solves issues.
I personally wouldn't use ESEutil and Isinteg without Microsoft support. Most of the checks and finally a repair can't be run against an online database. So if you can't move mailboxes to another DB you will have downtime. Depending on your hardware it could be a short or longer one.
First read these two articles and then stick to the Microsoft documentation.

But first of all wait for some more hints. Maybe the "corrupt database" thing points into a totally wrong direction.
