Searched around for a bit, and most threads on this topic seem to be related to using BES.
I had a Curve up until last week. When I delete messages in Outlook on my PC (standard POP mailbox, not Exchange), they would usually disappear from my BB within 30 minutes. Now I upgraded to a Tour last week and this is not happening, I have to delete in both places. I'm sure it is just a simple setting I am missing but can't find where it should be. I do have the reconciliation: on conflicts: set to Mailbox wins.
Anyone know what is causing this?
Other then this, really enjoying the Tour. I'll be going overseas next month so we'll see how well Verizon handles that.
I have a POP3 account and in my settings on the Reconciliation screen they are:
Delete On: Mailbox & Handheld
Wireless Reconciliation: On
On Conflicts: Handheld Wins
When I view emails on my PC and then subsequently delete them, they also are removed from my BB in a short amount of time, similar to the OP's statement of within 30 minutes.
