SYMPTOMS
Multiple users cannot log on to their own primary mailbox on the Exchange Server computer. When they attempt to open their mailbox, they receive the following error message:

The set of folders could not be opened. You do not have permission to log on.



CAUSE
The users do not have permission to connect to the Exchange Server computer. By default, everyone has the "Access this computer from the network" permission. If this setting is removed on any domain controller (DC), it affects all DCs in that domain. Therefore, limiting access on a remote DC can inadvertently lock out users, if Exchange Server is also on a DC.

The same problem can also occur if this user right is removed on an Exchange member server.



RESOLUTION
To resolve this problem:
 * 1) Start User Manager for Domains on the Exchange Server computer.
 * 2) Click Policies, and then click User Rights.
 * 3) Under Right, click Access this computer from the network.
 * 4) Click Add.
 * 5) Click Everyone, click Add, and then click OK.
 * 6) Click OK to apply the changes.



MORE INFORMATION
If the Exchange Server computer is a domain controller, you can also try to connect to the Netlogon share from a client to see if the user can connect to the server. From a command prompt on the client computer, type the following command:

net use \\ \netlogon

The user does not have access to connect to the server if the following error message appears:

System error 1385 has occurred.

Logon failure: the user has not been granted the requested logon type at this computer.
