While trying to troubleshoot some issues with a user’s flaky VPN connection (they could get connected but couldn’t ping anything on the company network), my first guesses were that it was either a routing issue and that IPv6 might be the culprit or that it could be an MTU issue. In searching for the answers on how to disable IPv6, I had stumbled across a blog article that, while seemingly helpful at the time, had some misleading information on it that caused some rather undesirable results. It gave me an incorrect registry value setting of “0xffffffff” that actually caused Windows to take an extra five seconds to boot.

Exchange 2010 OWA – Outgoing Attachments Not Visible in Compose New Message Window
For about the last nine months to a year, I have been having ongoing problems with Exchange 2010 OWA with SP3 not showing attachments on outgoing emails. Even though the attachments would still get delivered, the location where the attachments would normally show up had completely disappeared and you couldn’t remove items after attaching them. I can personally vouch that this issue affected IE8, IE10, IE11 on PC and Google Chrome on MAC. As for Firefox or Safari, I can’t really remember whether they were affected or not and since it’s already fixed I have no way of testing it.

- Delete an entry from the list using OWA
- Login to mailbox via OWA
