1. One of my folders has a "/" in its name. Modest does not like this. Fortunately, it doesn't seem to have trouble viewing e-mails in it as long as I catch the notification.
2. Desktop widget???? My E51 only showed the two most recent e-mails, which wasn't great, but at least that made it easy to see if I had new messages.
3. So I click the @, and I'm shown "Mail For Exchange", and I have to select that every time, even though it's my only account. That might be slightly useful, if it didn't think when it was last updated was more important to tell me than if there are new/unread messages (Hint: it's not).
4. My account is configured to automatically move certain e-mails to subfolders. Once I've opened up my account, there's still no indication as to whether or not/how many unread e-mails there are. I have to scroll though the whole list to see if there is anything unread in my subfolders.
5. My most commonly used subfolder starts with "R". Since they are listed alphabetically, starting after all of the inbox/sent stuff, I need to scroll down through 4 pages of folders before I get to it. Reordering folders would be good, as would being able to hide folders or collapse sub-subfolders.
