We are migrating from Domino 8.5.3 to Exchange 2013, the server is patched up to date, we have multiple conversions running. However, they are all running at an extremely slow pace, around 2 to 10 mbps. Been trying to troubleshoot, looked at the network, I don't think it is a network issue have tested, used tasmo, wireshark can't find anything. The error we see is Error: Set Props --MAPI reconnected 80040125 Attempting Retry. Does anyone have any idea how to troubleshoot from here?
Thank you very much.
