Public folders do not replicate correctly after installing Symantec Mail Security for Microsoft Exchange on Exchange 2010
Last Updated May 06, 2014
After installing Symantec Mail Security for Microsoft Exchange (SMSMSE) to my Exchange 2010 environment which ensures high availability with Database Availability Group (DAG) and public folder replication, public folders no longer replicate correctly.
SMTP transport virus scanning is enabled in SMSMSE. This extra processing can cause timeouts in the public folder replication process: public folder replication on Exchange 2010 still uses SMTP rather than the methods used by DAG for mailbox databases.
Disable the "Virus scan messages during SMTP transport" option in the SMSMSE console:
Open the SMSMSE console.
Navigate to Scans -> Auto-Protect
Under "Advanced Scanning Options" uncheck the box next to Virus scan messages during SMTP transport and click Deploy changes.
Public folder replication should now complete successfully.
Microsoft Exchange 2010
Database Availability Group is the cluster type.
Exchange 2010 Hub role is installed on the server.
