I'm facing a problem with OutboundEmail Synchronization for Contacts.
We have the following scenario : 2 load-balanced CMS servers and 3 load-balanced CDE web servers located in different data centers. Each CDE web server will have it's own SQL server for broker DB and OutboundEmail Subscription + Tracking DB.
If I install local OutboundEmail Subscription + Tracking DB on each CDE, how can I process the Contacts Synchronization from the 3 CDE servers, knowing that for a specific Tridion publication you can only specify 1 synchronization target containing 1 url to profilesync.aspx ?
And idem for Tracking Synchronization.
I must be missing something ...
Any suggestion please?
