Hi there,

we have a really strange behaviour of Outlook and SmarterMail if we integrate
SmarterMail Calendar as a SharePoint List in our Outlook (SharePoint Sync).

In detail: Everything works fine except that we cannot delete or change instances of appointment series (say we have a weekly meeting for 5 times on friday and want to delete the first entry).
The instance gets deleted in the local outlook profile (by user A) and everything seems to be fine.
But, on the server side (means the SmarterMail Webmail account) the instance of the appointment series is still there and every other user (call it user B) which has mapped the calendar is still having the instance-entry in his Outlook calendar.
It even gets worse if that other user B is changing the presumed deleted instance. In that case the instance is
coming up even on the outlook profile of user A who has initially deleted the item.

We can see on the SmarterMail Server side that the instance wasn't deleted and is still there.

That raises a few questions:

1. Is the function of deleting a instance of an appointment series (in Outlook) not supported through SmarterMail SharePoint Sync ?
2. Does anyone else faced that problem before and has found a solution to it (client or server side) ?

Some technical facts:

Using W2K12R2 Terminal Server with Outlook 2013
SmarterMail Calendar is integrated as a Sharepoint List by using the "Add to Outlook" function on the
SmarterMail Server side.

Any hint is really appreciated.

Thanks in advance
