After having set up my new MacBook Pro last week and running fine with Hotmail/Entourage (over my Comcast/Linksys - no WEP Key needed), I encountered the notorious Error 3259.
I have two internet services, each going through their own Linksys router. Comcast (no WEP key required) and Verizon (WEP key protected). I was always using the Comcast service with my new MAC (hotmail/entourage)...until...
The Comcast service and Linksys system went "down." When this happens, I simply roll the MAC over to the Verizon service/Linksys. When I went to Verizon internet, that is when the "SEND" problems started.
Remember, the difference between our Linksys (connected to Comcast modem) and Linksys (connected to Verizon modem) is that the Verizon is WEP key enabled, the Comcast is not.
After struggling for two days and getting NOWHERE, I became curious about the timing of Error 3259 and the switch from Comcast to Verizon service. So, I reset the Comcast modem/Linksys, and switched from the Verizon/Linksys BACK to the Comcast/Linksys...I was shocked when it immediately started working. and continues to work.
Is there some connection between security/WEP protected internet service and Hotmail via Entourage?
