Consider the following scenario:
This problem occurs because Exchange Server 2010 does not support that the MAPI client application calls that look for an alternative public folder when the default public folder database is unavailable. Therefore, the MAPI client application keeps trying to connect to the default public folder database instead of trying to connect to other public folder databases in the referral list.
To resolve this issue, install the following update rollup:
2425179Note Client redirection occurs only if the server that hosts the specified public folder database is not available. When the server that hosts the public folder is available, client redirection does not occur if a public folder database is dismounted. In this scenario, the client cannot open a public folder even when the update is installed.
