|Message:||The Microsoft Exchange Replication Service was unable to perform an incremental re-seed of the passive node for storage group %1 because replication was suspended for this storage group. To resume replication for this storage group, use the Resume-StorageGroupCopy cmdlet in the Exchange Management Shell.|
This Error event indicates that the Microsoft® Exchange Replication service (MSExchangeRepl) could not perform an incremental reseed of the passive database copy because replication was suspended for the storage group specified in the event description. This event is caused when an incremental reseed must be initiated but the storage group copy is currently suspended. Incremental reseed must see the active log stream in order to perform its operation.
The Microsoft Exchange Replication service tries to perform an incremental reseed after a failover if the passive and active database copies for the specified storage group are out of sync. An incremental reseed is performed to avoid a full reseed. The replication service detects that the copy of the database on the active node has diverged from the copy on passive node when the passive node is restored and tries to resynchronize with the now active database.
Note Incremental reseed cannot detect log file divergence until there is traffic to the storage group.
The event will only appear when the passive node returns to service after it has been previously active and then failed. Generally, there are three conditions that can cause the database to diverge:

To resolve the error, the administrator can do the following:
If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
