Hello,

I've searched around for an answer to my problem, but have been unable to find a solution.

For the past few weeks (since the 14.3.7 update-- I think), if I create an appointment in Outlook 2011 on my iMac or MacBookAir, it does not appear on the other computer, nor OWA, nor Outlook 2010 on my Parallels Windows 7,  nor my devices (iPhone, iPad). 

However, if I create an appointment in Outlook 2010 on my Parallels Windows 7, or Apple's Calendar program on my iMac or MacBook Air, or on OWA, or on my iPhone or iPad, they appear on my Outlook 2011 on my iMac and MacBook Air. 

So in layman's terms, it seems that Outlook 2011 on my iMac and MBA cannot push the appointments onto the Exchange Server to be seen by other computers and devices enabled with my Exchange Account, but Outlook 2011 can pull appointments off the Exchange Server if they were created on other devices or programs. 

I removed the Exchange Account in Outlook 2011 on my iMac, and then re-added it back, but it still doesn't work correctly. For some reason, it will only upload about 10 of my 3000 contacts, but I think I can fix that (hopefully without duplicates!).

Of note, I had about 30,000 duplicate holiday appointments, but I deleted those (now have about 1800 appointments). I don't know why they reproduced. They were only the holiday appointments that you can import from Microsoft (and one birthday). 

Appointments used to work perfectly on Outlook 2011, and I suspect the new update may be a culprit. I've been using Outlook 2011 with Exchange server flawlessly since Outlook 2011 came out. 

Any ideas? Thanks. 
I have upgraded my iphone to iOS7, hotmail / outlook emails are coming through & sending fine, but my calendar is not working properly at all.  The only appointments visible on my iphone are reoccurring appointments, some of which are not accurate as they had previously been deleted. I cannot add new appointments either.  when I first load up the calendar on my iphone it sometimes flashes up with the correct appointments & invitations, but they disappear almost immediately.  When I check to ensure the correct calendars are selected, they are set up properly.

When I log into my hotmail calendar, this months appointments are showing fine, but if I scroll to next month I get the following error message:
Calendar error
There's a problem with displaying your events and tasks at the moment. Please try again later.


I have tried deleting & installing my account from my iphone, but this has made no difference.

I have tried making amendments to calendar entries from my hotmail calendar on my laptop - my laptop updates fine, but nothing on my iphone.

I have tried sending invitations to my hotmail calendar, from my work Gmail calendar - the invitations come through to my iphone but disappear as soon as i click onto them (sometimes before) & if i try to add the calendar appointment from the email received in hotmail on my iphone it doesnt work, but it works fine from my laptop!

Help!!!

My Outlook calendar is synced with my cell phone.  Calendar was working fine today then suddenly all the appointments disappeared.  I have tried deleting my email account from the phone and re-adding it. restarting the phone, and logging into my account from a desktop.  Even on the desktop all my appointments are gone.  How can I recover this???
(Moved to a separate discussion. Was posted on a discussion about categories.)

Good afternoon everyone from a novice and luddite.  OK, here is the problem;

I am running Outlook for Mac in MacOffice 2011 and also have parallels running outlook 2010 for windows.  I am trying to post appointments on my Mac version that will then synch to the Outlook 2010 and, subsequently to the microsoft exchange version that sits in our head office.  Our It support company says that it has never heard of this, but I am convinced that it worked previously.

Can anyone shed any light?

Outlook Calendar started showing the appointments I had scheduled for 2012 with my appointments for 2013.  When I go back and look at my 2012 calendar my 2013 appointments are showing up as well.  The calendar was fine a few days ago, I turned off my computer Sunday night and Monday morning the calendar is doing this crazy thing.  What is going on and can you please fix this problem?
Hi!

  I recently wanted to sync my calendar app with s planner on my galaxy phone. This, I thought, was easy and went well just adding my hotmail account on the phone and selecting sync calendar. Then I suddenly realised all my appointments showed up one day early on my phone. I logged in to outlook.com and discovered it was the same there. After researhing some I checked/changed/changed-back all time zones and locations on all devices.
  So right now, when I add new events from either device it will show up correctly on all devices. My old appointments (entered before, not past date) is still correct in the windows app and one day early on web and phone. I'm hoping there is a way I can force outlook.com to resync from the windows calendar app(?) and that that will fix my problem. Anyone? Help? :D

Regards, Torgrim.
 outlook.com calendar doesn't show appointments created on my Samsung Galaxy S3. But the phone does show appointments created directly in the outlook. com calendar.
My manager wants me to fill out his calendar, but he doesn't want to have to accept all the invitation emails.  If I don't send the invite, they do not appear on his calendar though!  Is there a way to add appointments to his calendar without having to send invitations?
Thank you,

Hi.  I live in Europe and am travelling this month throughout the US.  I scheduled several appointments into Outlook.com calendar (which is synced with my Lumia) and since I've arrived in America and my phone is now on EST, all of my appointments are showing up as if the appointment were schedule for CET.  

Is there an ability to create a calendar that is time zone agnostic?  

I've also tried to go through the Outlook.com Calendar and change the time zones for the events to EST, but then they're shown incorrectly on Outlook.com because that calendar is set to CET.  Shouldn't there be away to account for multiple time zones in a calendar?  My calendar is an absolute mess right now!

Thank you

EDIT: Upon further research I've discovered there's no proper fix of the kind that I'd like.  I've since edited all of my appointments on Outlook.com with the correct time zone information.  It looks weird on Outlook.com, but it appears correct in my phone.

Still, if someone from Microsoft reads this, there really NEEDS to be an option to edit time zone information on the phone, or to create a time zone agnostic calendar or something like that.  I won't have a laptop with me for most of my trip, so my phone will be my primary input so I can't rely on Outlook.com.  It's currently not a very "mobile-friendly" solution.
