Re: UEA
My experience of Office 365 is that it is so slow and useless I'm surprised whoever it was managed to compose the email and get it out in the first place.
"Mark all as read" frequently causes the system to become unresponsive for 30 minutes or more.
"Manage rules" pops up a freaking MODAL window at every stage, including the "updating server" message, so nothing can be done while it is deciding whether to hang or not.
Slow network doesn't help, but there were serious lack of smarts at work when the client processes were being "thought" out. Thunderbird is way more civilized when it comes to not locking up the entire application with unnecessary modal wiindows.
