[horde] Tasks Appearing on Horde from one phone but not another

[John McIntyre]

Hello,
I've had horde running on a Linux CentOS 6.5 box for a year or so, and
where webmail and calendar is concerned, it has been functioning perfectly.

There were issues getting my wife's Android to deal with the calendar, but
in the event, I just added the account on her phone, using my credentials,
and everything's fine.   We can add events on any device or on the web
interface, and it syncs to all devices, perfect.

The only problem has been the tasks list.  If I try to add a task using the
web interface, it immediately throws up a 404.  So I gave up, and just
contented myself with using tasks on my iPhone, and my wife was using a
separate task list app on her Android.   Even when I created a task on my
iPhone, it never appeared on the horde, but that's fair enough.

This morning, she asked if there was any way we could share tasks, and so
she activated 'tasks' on her Android calendar app.   She added a task on
her phone, and it appeared on my iPhone.   And vice versa.

I got into the office, and as usual, fired up the horde and placed the
calendar on one of my monitors.  Imagine my surprise when the task that she
had created, appeared in the web calendar.  The test one that I had
created, however, didn't.

I deleted the exchange account from my iPhone, recreated it and tried to
create a task.   It didn't appear on the web interface.

Can someone tell me how I can fix this?

Thank you.
