Email needs an Unread folder that shows all unread messages like Outlook does, regardless of which subfolder actually holds the unread message.

Tap-and-hold to delete an e-mail address from the autocomplete list (e.g. misspelled e-mail addresses), and/or option to delete e-mail address history (reset autocomplete list, to only show e-mail addresses from contacts)

Currently WP7.5 does not sync to or save new drafts to Gmail drafts folder. This is a much needed feature.

Or better option :
2 choices in menu : "Delete" AND "Archive"

Please ! I must connect on a PC to delete :\

Email alerts do not work for subfolders under inbox unless folder is pinned to the start screen. Need alerts for Exchange rules that move email

Being able to send out emails on your phone with your alias email address you have set up on your LIVE.com account.

Make it so we can attach Office documents or other files on the phone / Skydrive to a new e-mail.

don't delete emails from the mail server when they're deleted from the phone

The Draft folder is no sync on Windows Phone 7 or 7.5 Please allow the sync for this folder as for other folders

15 minutes is too long, but every 5 minutes would be perfect

Many large enterprises won't consider WP7 if this is not an option.

Hi! Im using windows Mozart 7 Windows Phone. I really love this phone, but i would like to have one more useful feature in my google account settings. I have created a gmail account connection. Phone is downloading all my callendar events, emails, contacts and etc, but I really would like to have one more field to enter... An sender email. I have connected one email adress to my gmail account (contact@mydomain.info), and when someone recive email from me, sees that its not delivered from contact@mydomain.com not by mygmailaccount@gmail.com
Windows phone team.. Can You make my day?

Also allow for black background with white text in email app. On a super amoled screen in the dark it's definitely too bright now.

I use a Hotmail alias as a primary email address instead of the address associated with my Windows Live ID - I'd like to be able to compose messages from the "alias" address.

Currently only pictures are allowed to attach directly while creating email. Please allow office documents also instead of going to office apps and then attaching

Please allow to select multiple file attachment in compsosing emails (currently only 1 per email allowed)

hotmail mail app with search online: when you start searching on emails, gmail and exchange accounts give the chance to search on online mails, not only on local phone. Hotmail hasn't this feature, it's quite limiting.

Let me choose which account to send email from if I have multiple accounts linked to Gmail.
