Check the permissions in Active Directory

You can check for permissions in the Active Directory using the following steps-

1. Open Active Directory.
2. In the View menu, choose the Advanced option.
3. Select the user account that is getting the exception error. Right-click and choose Properties.
4. Go to Security Tab.
5. Go to ‘For special permissions or advanced settings,’ click Advanced.

2. Go to the Exchange server object and check its Properties.
3. In the Security tab, click the Advanced option.
4. Sort the entries with Column names and check the entries for Exchange Server.
5. Check if the following entries are allowed-
   • Store Constrained Delegation
   • Store Read and Write Access
   • Store Read-only Access
   • Store Transport Access

By default, these permissions are allowed by Exchange Server. If the permissions are denied, then enable them.

Check the errors logs in Exchange Server

When you start to get the Exception error, you can check the Exchange Server logs to find when did the error start to create problems.

1. In the Event Viewer, expand Windows Log and choose Application. Here, you can check the error logs also.
2. After checking the logs in the Windows Logs list, you can also check the same error in the Exchange logs. In the Event Viewer app, expand Microsoft>>Exchange. Here, you can see the Exchange related errors.

4. You should see if the error is associated with only a single mailbox or it is affecting the whole Exchange globally. You should connect multiple mailboxes with Outlook Web App (OWA) and check their logs. When there are more than one Exchange Admin Accounts, you should also check the same process with other accounts.
Check the database with the affected mailbox

The Exception error can create more issues in Exchange and affect the integrity of the database. So, you should check the status of the database with the following command in Exchange Management Shell-

Get-MailboxDatabaseCopyStatus
