I've recently moved from an ISP's POP3 service over to Hotmail. I'm using Outlook 2010 with the Hotmail connector. The connector is 32-bit, version 14.0.5117.5000.
In the main, Outlook is able to synchronise with Hotmail without too many problems. However, as I drag emails from the personal store (PST file) to Hotmail, I appear to have hit a bit of a brick wall. Some of the emails I've got are quite big and when I try to put them into my Hotmail store, subsequent attempts to synchronise break with "Network operation failed". If I remove the errant email back to the PST store, synchronisation resumes again.
Any suggestions on how I can get these large emails into Hotmail, or if the Connector team might be able to fix this problem?
