iCal events showing dahed line border

Can't help you out but I can back up your story. I'm getting the same thing with about 80% of my "Work" calendar events since upgrading to Snow Leopard on my new 24" iMac. It appears that the only ones showing as clear with the dashed border may have been copies of previous events pasted at a new date.

I'm getting it too ... can't understand why ... seems to be with events that have been manually exported from entourage (drag event to desktop, open in iCal) ... and repeat ... some have been moved, some haven't. Only happens with one calendar ... (only export from entourage in one calendar)

The events with clear background and dashed border are normally the meeting requests that you haven't Accepted yet. So double click the event, and when the popup appears, click Accept button (or Decline as needed).

I hope this helps.

Same here. It is events created in Exchange and opened via Mail.app. The missing piece (since Snow Leopard) is that there is no opportunity to accept the meeting.

Interestingly, iCal thinks it belongs to the right calendar -- it just doesn't color it. More interestingly, it looks correct when synced to iPhone via iTunes!)

Same issue here.

When I made the switch to Snow Leopard, I observed this behavior - all my iCal events from work turning grey/white, with dashed lines. Over time, as I received new invites from work I noticed that they were coming in properly colored, so I figured the grey/white events would eventually disappear over time and I would just live with it.

I was performing some system maintenance this weekend and noticed that my "~/Library/Caches" directory had grown to ~1.5GB. In the interest of recovering disk space I deleted the entire contents of "~/Library/Caches." I've done this many times before, without issue. When I later opened iCal, I noticed that all of my work events (events that I received by e-mail invite) had turned back to grey/white, with dashed lines. I later found out that when I dumped all the caches it included this folder: "~/Library/Caches/com.apple.iCal."

Another piece of the puzzle....

Hi there.

I am having the same problem here. I migrated to a new MacBook Pro from my previous one using a time machine recover and most of my iCal events turned grey with dashed line as border.

It seems that the events that are having this problems are the one initially created from Novell Groupwise (I am forwarding them automatically to my Mail app so that I can double click on it to have a copy in iCal).

Any help would be appreciated.

Again, not a solution, but an echo.

My Mac Mini performed an automatic update yesterday, and when I today turned it on and opened up iCal, several of my events have been made clear with a dashed border.

For me it appears that all of the dashed events are repeated events (although there are other repeated events that have not been dashed).

It's a Microsoft Exchange calendar but as far as I can remember all the events were created in iCal (though some may have been made in Entourage during an iCal tantrum).

And now, just a few hours later, without me doing anything to them, most of the events have returned to normal with just a couple retaining the dashed outline and colourless appearance.

Most odd.

I observed this as well. Some number of my calendar events had a dashed line border. However, when I executed the "Calendar/Refresh All" command, the entries changed to the color of the calendar with which they are associated. Presumably, for some reason these (seemingly random) entries needed to be re-synced with our Exchange server. They all look fine now.

I had the same problem when I imported my Outlook data. I've had to re-accept each appointment for it to change to the relevant calendar colour.

I did however somehow manage to become the organiser of one of these imported items (where I was only an attendee originally). I think I did this by editing the appointment before accepting it and have no way of changing it back other than to delete and ask the real organiser to re-send the meeting request.

Oh well, I'll get used to this Mac stuff soon!

Hard to believe there's no solution to this yet... I've got some of those dashed white events and I'd really like to correct that bug (I'm not using Exchange or any other calendar server). Even when copying and pasting such an event, it remains dashed....

I don't no if this is related to the 10.6.4 Update, but I noticed that random calendar events were showing up this way today. The calendar is an exchange 2007 calendar and is the only one I use for work.

This is what I did to resolve the issue, went into ~/Library and moved the Calendars folder to my desktop. Opened iCal and re-added my exchange calendar under preferences>Accounts and let it re-sync. Then deleted the folder on the desktop. You could probably get away with just deleting every thing in ~/Library/Calendars/"UID".exchange/ except for info.plist (which contains your exchange calendar server settings).

If you have local calendars *DON'T DELETE THE ENTIRE ~/Library/Calendars/ FOLDER* or you may loose your calendars.
