When a cluster is failed over from the active to passive node, the SMSMSE cluster resource fails.
The following events appear in the Event log of an Exchange 2007 Public folder Single-Copy-Cluster (SCC):
During a failover the transfer of the settings.xml file takes a long time when the file size is large. When the time to transfer the file exceeds the timeout this issue occurs. This situation typically occurs when a large number of public folders is written to the settings file. This may also occur if a large number of mailboxes are written to the settings.xml file.
SMSMSE 6.0.10 and higher has a workaround whereby the scans can be set up to run on all or none of the mailboxes or public folders. This workaround introduces a limitation so that individual mailboxes or public folders cannot be selected.
Upgrade to 6.0.10 or higher. Then perform the following steps to set up a registry key.
