    I've been having this issue for a long time now.
    If I add an entry on my PC connected to the Exchange server, it appears on my WP10 phone (Lumia 830 with the latest redstone build). But if I add the appointment on my WP10 Outlook, not only it doesn't show on my PC but it disappear from the phone after a few minutes.
    First I thought it was some kind of setting at the Exchange Server level, but I have no problems doing it from an iPhone.
    Has anyone had the same issue?

    WP 10 Outlook sync with Outlook.com, not your Exchange Server. Have you add your Exchange Server to WP 10 Outlook Calendar via hamburger menu?

    Thanks. I'm not sure I understand. I added the account via the regular way. I can see my appointments coming FROM the Exchange Server with no problems but my phone wont send the appointments TO the server.

    So you can see appointment made from your Exchange Client on your phone. That means phone side is pulling appointment from Exchange Server.
    Your Exchange Server client cannot see appointment made on your phone. Have you added your microsoft account to your Exchange Client? On the PC side?

    yes. the server has everything right. In fact I discovered that once in a while my phone will be able to send the info to the server but 99% of the times it won't.
    I even tried to leave the Outlook app in my phone open for a long while (suspecting that may be it was a multitasking issue) and as soon as I close the Outlook app and the I open it again after a couple of minutes, the appointment is gone.
    Can't see how Microsoft is trying to gain enterprise customers if the calendar doesn't work properly.
    It is a shame that I will have to switch platforms (probably back to boring iphone) to be able to be productive. I depend on the ability to book appointments outside my office.

    There is no need to mess around with Exchange Server setting. This is just a setting problem on client side, PC and / or phone. The fact that your appointment disappear from the phone indicates that the appointments are synchronized to something at somewhere.

    So, for the phone side:
    1. Is your Microsoft Account connected to Hotmail (or its reincarnations) address or some other mail address (Gmail etc)?
    2. Open the Calendar App, open the ellipsis menu ( ... at the bottom right corner), go to Manage Account.
    3. Is your Exchange Account listed on the Accounts?
    4. If yes for no 3, tap that Account and pick Manage.
    5. Scroll down and tap the manage sync setting.
    6. Scroll down and see if the sync for Calendar is on. Turn On if you see it is Off.
    7. Hit save and exit.
    8. If no 3 is no (unlikely since you can see appointment made from other devices), add your Exchange Account.
    9. On Calendar App, tap the hamburger menu on the upper left corner of display. It lists all calendar displayed. Is your Exchange Account listed on the calendar lists?
    10. If everything is already alright on steps 1-9, and appointments you made on phone still don't displayed on your Exchange Server, Open the Accounts Settings menu (Start, All Apps, Settings, Accounts, Email and Accounts).
    11. Scroll down on the Accounts used by other apps tap Add work or school Accounts. Add your Exchange Account there.

    On your PC/desktop/laptop:

    1. If you listed your main Microsoft Account is not a Hotmail address, open browser and log-in to your address. See if you could find those missing appointments.
    2. If you have any other accounts listed on your phone besides your main Microsoft Account and Exchange Account, login and check with browser and see if those appointments are listed on those accounts.
    3. On your desktop mail client, I am guessing you are using Outlook, is the main Microsoft Account connected to desktop Outlook?

    Let me know how it works.

    Thanks for your reply!
    Everything looks good on my phone and on my PC.
    I still have random disappearing of appointments if added via my phone.
    I checked (for the sake of experimenting) adding appointments on my wife's iPhone (that is also connected to my Exchange) and our iPad (also connected to my Exchange) and there is no problem whatsoever with those devices. As soon as I add appointments there, the appointments show on my phone within a minute.
    But when I add appointments with my Lumia 830... good luck. Sometimes they reach the server and sometimes the don't (most of the time they don't).
    I'm wandering if it is related to some kind of background processing (multitasking) on WP10, because I had no issues on WP8.1.
    Thanks!

    Huh, didn't know they haven't fixed that silly old Outlook Mobile setting. Basically in the old Windows Mobile pre iPhone era, changes in calendar are not commited to Exchange server until next scheduled sync/heartbeat (to save battery) or an email event (memory rather hazy at this). Could this be it?
