I actually belief that NVDA only says has appointment in the day view when you come across a date that has an appointment in the specific time slot that is selected. Having said that, there are probably many people who do use the Outlook calendar much more often than I do. cc @dkager @bramd

@feerrenrut: agree with giving this a p3? It can be quite annoying to walk through days in the calendar and miss the fact that a day has appointments. On the other hand, the month view does not have this problem and feels a bit more usable to me.

Yep, happy to give this a P3. Given there are other ways to achieve the task.

Coming back to this, @bramd and I have found another case where this fails.

1. In the outlook Calendar, enable two calendars
2. In the folder/calendar tree view, select the two calendars. IN the context menu, select overlay.
3. Calendars are now merged, but when using left and right arrows to navigate through the days, only for one calendar the appointment status is announced.

@feerrenrut: Mind if i Increase priority to p2 to investigate this myself? I will report back when I have more information.

@LeonarddeR Yes, this might be exactly the same issue. Hard to say without a look at the code though.

I'm afraid there is no way to fix this using the outlook object model:

1. To determine the start and end date and time of the currently active time slot or day, NVDA uses the current view object to fetch the start and end date of the selection. It seems that view objects do not expose information about the amount of appointments in a selection.
2. To gather that information instead, NVDA fetches the current folder object and checks whether there is an item in that folder within the selection start and end of the view. If an item has been found, NVDA reports "has appointment".
3. The problem here is that a view can display multiple folders (e.g. in the case of two calendars in one view). However, only one folder can be the current folder. The current folder is the folder that contains the last selected appointment. So if you're moving to another time slot that contains an appointment in another folder than the one Outlook considers to be the current, NVDA won't announce "has appointment" even though the view displays one.

The only way I've found to work around this, is the IAccessible name of the view object, which contains information about how many appointments there are. However, the name contains quite a lot of comma separated information, and I'm afraid there's no reliable way to filter out the required information, unless someone comes up with a proper regex.

I've investigated this using Outlook 2013. Where Outlook 2016 exposes information about number of appointments using MSAA, Outlook 2013 and older does not. Therefore, we must rely on the object model here. This issue is caused by a limitation in the object model as noted above. I've been able to replicate this deficiency in JAWS 2018 with Outlook 2013.

I'm closing this as can't fix. Relying on MSAA for this in Outlook 2016 and newer is beyond the scope of this issue.
