I received a meeting invitation with an attached .ics file. The message contained options to accept or decline the invitation. I accepted, and the message disappeared. I subsequently found it in the Deleted items folder. If this is intentional, it's a very strange idea and I would hope it won't happen again.

In the old calendar, when right-clicking on an event and selected categories, I got a drop-down/sub menu that listed all the categories with a scrollbar. This allowed me to set any category using only the mouse. In the beta, a limited list of categories is displayed, requiring me to type to get a category that wasn't listed. Why remove the scrollbar?

Why can't I have a larger font size on my Outlook calendar so when I print it I can see it?

This would be helpful in case someone leaves the company or changes his function internally and has reserved certain meetingrooms with an appointment series. Right now the current organiser has to cancel the series and at the same time the other person who takes over needs to send a new invitation. However there are always problems with this method and it's quite time consuming to copy the series manually. Would also be a nice feature to have for general appointments.

Your calendar, in theory improved, does not send remind email. This is very unfortunate. It was working perfectly well, and suddenly I missed few things (to call doctor for my chirurgical intervention set up date for example) because I blindly believe for that reminder. Will make adjustments quickly?

Subscribed ICAL web url calendars no longer synchronizes after Sepmtember 18th Outlook.com update. It had worked for more than one year. I also tried to subscribe the same calendar in different Microsoft Account and it doesn't work either. Note the ICAL web link itself is ok. You broke it, fix it.

Would be really nice and useful to have a option to decline an invitation but keep it on agenda (as free) if some change later allow you to attend or if you need to keep in mind this meeting is going on (for debriefing or whatever other reason).
