Monochromatic & Bland

Calendar portion will not show the various color coding of Google Calendar. Will not load optional/additional calendars. Will not sync with Sunrise Calendar (a Microsoft product!) or it's additional calendars of interest. OneCalendar is much closer to Outlook Calendar functionality. If you were to port Sunrise Calendar, you would be MUCH BETTER OFF! Email portion will not update nor can I access account settings, does not show Google Colors either. I had to delete app, reinstall and reset my accounts. Now working OK. If I could find a good email app, I would delete all of this offering. A total mess, Microsoft NO help. Regret changing back from Android!

This app does NOT open on my machine anymore

Shortly after upgrading from Windows 8.1 to Windows 10 on my machine, this application would no longer launch. I had a Calendar icon on the Taskbar which disappeared. The space where it should be is still there...just no icon anymore. I tried to right click and unpin from the taskbar, but it remains. I cannot launch the Calendar or Mail apps from the Taskbar, Start Menu, or via Cortana. They simply do not do anything when clicked. Clicking the icon will not launch the application (I checked and the app process never starts). It's as if they have been disabled. In addition to these problems, the Live Tiles for Mail and Calendar are static and do not show any content. I wish I could attempt to uninstall/reinstall but uninstalling is not allowed for this app. This is a MAJOR issue. I've seen many others online with the same problem, and no resolution from Microsoft. PLEASE FIX THIS and I will be happy to rate again.

Shitty ! Someone should be fired !

I mess entirely my calendar. I create new event on the calendar app and it does not appears on my phone. I create new entry in my phone and does not updates in my calendar app. I change the time of the appoint and it doesn't update in the app. By comparing, in the Outlook app, everything is updated correctly and in real time. But Cortana can't integrate time based reminders in Outlook tasks (thanks to another "big brain thinker") so at the end it looks like this: 1. I paid for the organizer skills of Cortana; 2. I paid for the Office package because the Email and Calendar default apps can't sync between devices 3. I'm using 30% of organizer skills that I paid.

Horrible app. Poorly executed

Does not sync Gmail well, it is stuck syncing often. No always up to date Pinning of multiple accounts to start screen is very hard to discover Even if u manage to pin an account to start it opens up with the last account and takes a few seconds to switch the account requested. Something tells me databinding is really messed up.

Needs Lots Of Work

You can add multiple accounts, but there's no unified inbox. This means lots of touches to see them all. Also, there's no bulk select for emails. This means lots of touches to select and delete junk....lots of junk. And, you get no choice for colors/themes. This means your battery gets sucked down by the bright white and blue and if you're visual acuity isn't that great (like mine) it's hard to see. There's really nothing good to say about this app right now. But, I think Microsoft will eventually fix it. I'm still using it on mobile, but have stopped using it on desktop.

Completely useless in comparison to Google Calendar

The calendar version initially used in the WP8 OS were far more robust and functional. It used to appropriately manage my schedules and appointments. Google Calendar handles these from my outlook mails way better.

Too many problems

It does not manage DRAFTS. You loose all your Win 8 drafts and looses current version drafts. Its interface with Google is terrible...won't sync. Search doesn't work properly. ... I can't post all the issues but mainly looses your work...past and present.

*Edited Review* Decent App

Email app, does what it's supposed to do. Adding multiple accounts is quick and easy. I used to hate this app compared to the Win8.1 version because it wouldn't sync my mail at all and some basic functionality you would expect from an email client was missing. However, those things seem to have been rectified in an update as I can't say I have any complaints now and am getting back in the habit of looking at my email. Still missing a way to select all messages in the currently viewed folder for quick deletion but otherwise I have no complaints.

So frustrating to use at times

These apps make the 8.1 Mail and Calendar look amazing. Seems to have forgotten most of my contacts. Copying text from emails into an email to send often doesn't format properly (bulleted lists are goofy). I would like to pop an email out into it's own window. Sync often fails and tells me my settings are wrong, but after an hour or so seems to be fine again.
