Outlook calendar 'changes' appointment into a meeting after editing.

Hi,

I have started to experience the same issue since about the same time (April 2018).

I use Outlook (Office 365) on Windows 10 (1803) for a desktop email client.

I have a few mailboxes synching on this client - including Outlook.com and Office365.

The issue only happens with Outlook,com email address.

Any appointments I create in my Outlook.com calendar in Outlook on the desktop show as appointments in Outlook on the desktop.

However, on iOS (11.3 on iphone 8), the following behavious is observer:

a) In the iOS built in Calendar, I can edit the appointment, but it then treats the appointment as a meeting, sending a meeting update back to my outlook.com email address.

My outlook.com address is shown as both the organiser and an attendee in the "meeting" on iOS

b) In the Outlook mail client on iOS, I am unable to edit the appointment. It shows as a meeting with Organiser being my outlook.com email address, and the same outlook.com email address as a participant

Somehow, iOS (Outlook and inbuilt Calendar) seem to be unable to tell that the "organiser" is me.

This article seems to describe something similar, but with some technical details:

I have the same issues - Appointments created in Outlook (PC) appear as meeting in Outlook for IOS App and so cannot be edited.  My calendar account is my outlook 365 account, although I use Gmail as my default mail account.   I have been using any one of 3 workarounds -

1 In Outlook PC I open the mail section and select my 'gmail' account, then use menu tab for new item.  Create an appointment and this for some strange reason creates an event that appears as an Appointment (and is thus editable) in Outlook for IOS.

2 In outlook PC Calendar create an Appointment and invite myself (i.e. create a meeting) - this does the opposite of what creating a appointment does - a fully editable event is created in Outlook for IOS!  Only drawback is that changes create email updates.

3 In Outlook for IOS, create an event - this can then be edited on Outlook PC without affecting it in Outlook for IOS.   It can also be used as a blank appointment that can be copied and used to create other appointments in outlook PC that appear as appointments in Outlook for IOS and thus fully editable.

After Windows May update, I had to modify my workaround to prevent Appointments from being  converting into Meetings. I still use Windows 10 Calendar when creating Appointments on my computer, but I switched to using Outlook for iPhone when editing them on my iPhone. After the Update, Appointments started becoming Meetings when edited using Apple's Calendar App. Also after the Update, formatting changes to double-space when Appointments are viewed using Apple's Calendar App.  If you have similar problems, please help Microsoft Community by clicking reply and submitting details of your problem (and your solution if you have one).

Thanks for the update MG.  I am following up to see if I can find out more details on the fix plans.  If I get anything useful I'll post back and share.

Gabriel, today I am continuing to have the problem that Appointments created with Outlook for Desktop become Meetings when edited with Outlook for Web, Outlook for iOS, or the Apple Calendar App. Workaround is to use Windows Calendar App to create new Appointments on computer or use Outlook for iOS (or Apple Calendar App) when creating an Appointment on iPhone or iPad. Today Outlook Support indicated that they are working on a permanent fix.
