Hi all,

I've got a problem at the moment with two Mac Office 2011 users - one a delegate of the other.

The delegate creates a meeting request in their calendar, inviting the other user. They then go into the other user's calendar and accept the invite.

In their version of the other user's calendar, the invite accepts and looks fine. If they open the appointment, it says words to the effect 'You accepted this invite at..."

On the other user's mac in their calendar, the invite shows up initially with a dotted line outline and time shown as tentative. Once accepted, the time changes to busy, but the dotted outline remains and the whole invite is greyed out. To this user, it looks like the invite hasn't been accepted, even though their delegate has done so.

This means we've got some conflicting information going on which seems impossible since their both looking at the same calender? Delegate has the appointment accepted, saying as such, but the main user only ever sees it as tentative. Which obviously causes some confusion if they're not sure if they're supposed to be in a meeting or not...

If this user then accepts the meeting themselves, it accepts properly, goes solid colour, the dotted line becomes solid also, and they see the invite as accepted. But obviously the point of delegate access is to do away with the need to manage your own calendar.

Oddly, considering the users involved, this calendar isn't shared to an iPhone or accessed elsewhere, so there's no syncing issue there getting in the way.

So why isn't this working as expected?

-- The delegate is set up for full access in the delegates options on the main user's Outlook.
-- The delegate has Full Access and Send As Access configured on Exchange.
-- They have no problem adding, deleting or altering calendar appointments aside from this. There are no errors thrown at any point.

We've tried:

-- Various combinations of delegate access and exchange access to see if one set is conflicting with the other. No change.

-- Database/Identity rebuild for the main user. No change.-- Setting option in OWA to stop invites automatically appearing as tentative. No change.

-- Allowing plenty of time for syncing in case the delegate is causing a problem by accepting too fast.

-- Lots of making sure we're in the correct calendars etc.

I guess this is fairly easily worked around, but annoying it doesn't work as they would like it to. Would just like to get to the bottom of it now!

Thanks in advance for any thoughts, ideas, comments or solutions.
