Outlook connecting to wrong public folder database in exchange 2010

Hello everyone,

We are running Exch2010 with MBX servers in DAG. Active DBs in prod site and Passive DBs in DR site.

We also have one PF DB in Prod site and 2nd PF DB in DR site.

All mailbox dbs are configured to use PF DB in Prod site but from last 2-3 days, we have checked that outlook is keep connecting to PF DB in DR site.

I ran below command to verify the PF db being used by DBs and all are configured for PF at Prod site

get-MailboxDatabase |fl Name, PublicFolderDatabase

Do you have any idea that why outlook is still connecting to DR PF when we have not configured it anywhere?

Thanks,

Vik
