I work for a customer that wants to use both an ipaq and a palm pda to sync up with the same mailbox and the software being installed on the same workstation.

Scenario:

He logs into his workstation which has both Hotsync and the Active Sync applications. He connects his PalmPilot and sync's that to mailbox A. He disconnects it then later that day he connects his iPAQ (Which is also wirelessly enabled when he is out of the office) and syncs to mailbox A as well. The customer wants to keep both devices and have both devices sync to mailbox A.

Are there any issues with this? Any white papers? Tech articles about this?
