Now user is enabled only to change the text style for replys in MS Outlook, but not only for inline comments. It would be a wonderful option to choose a separate style for replays and for inline comments as I would like to keep a standard style for general replays and choose a different coloured text for inline comments (to be separated in the previous e-mail).

I use Outlook, for both mail, calendar and contacts, often the category labels to bring order. However these are not searchable. It's a powerful feature especially if you use it when searching. It would be nice if there is a box where you can search the category * * * * quickly by typing a few letters, especially if you use many categories.

There are many users that have many rules activated on their Outlook accounts. In the Desktop client, you cannot easily search these rules to find ones you know to be out of date, etc. I spend far too much time sifting thru my rules to find the one I need to update, disable, or delete.

allow a link to your scanner when adding an attachment so a document can be scanned and attached directly to a new email.

Stop stealth updates. Your last update broke appointments, TELL us when you are going to apply an update, WHAT is in the update, and allow us to ROLL BACK if things get broken. So much time and frustration chasing a problem only to find out you updated things, changed or broke the way they work, and didn't tell anyone.

Being able to click on a previous email in a thread and that specific email opens in a new window with the attachments included in the original email

In the follow up a possibility to put a note, reminder or a result of a conversation

Currently, we can only insert bullets into Tasks. It would be helpful to be able to create checklists. Linking to OneNote is an immediate work-around.

It's very tedious to book the time slots in blocks of six months when the meetings aren't set in any pattern like once every week, monthly etc. I need to create separate calendar entries in such cases. Please provide a feature where I choose multiple dates as per my convenience on calendar and simply add them to a list. Lotus Notes offers a similar feature.

Other Outlook versions provide ability to search all email exchanges with a contact in Contacts by selecting "Activities" search. It very convenient and fast for finding discussions, attachments, etc. Searching through all emails for a subject, contact, word, etc., is ok, but not as business useful. Thanks.

Allow a sort option in the "Deleted Items" folder to sort by the date/time the item was deleted, rather than the original send date. This would allow easy location of recently-deleted items.

To show that new messages were delivered to the filtered sub folders. Also to be able to color folders in order to distinguish visually.

Office programs allow users to customize keyboard shortcuts in the "Customize the Ribbon" dialog window. Why doesn't Outlook? The "Keyboard Shortcuts: Customize" button is missing.

Something like sticky note that you could attach to an email, but would not forward with the email when you reply. (for user's eyes only).

Would be especially helpful if I could attach relevant files when filing emails (w/o sending a new email) or attach/connect other email chains so I could easily keep all relevant information together.

I would like to have the option to set a point in the map in the location field.

Outlook offers the option to send an email to all attendees of a meeting. It would be great to have the possibility to send an email only to attendees who have declined, or to those who have not yet answered. This would avoid unnecessary reminders to those who have already answered.

Find duplicate messages

Mailtips on all Outlook clients: when a mailtip about external recipient is shown, the external recipients should be highlighted in to/cc/bcc fields to make external recipients to stand out.
This should apply to at least Outlook for Windows and in web client version as well.
