[ipad] Outlook Shared Calendars

Danp · November 5, 2013

Anyone know of a way to view these on iPad? Can view them via OWA on a PC with IE when not in lite mode, but cant find a way to see them on iPad.

Install OWA for iPad off the AppStore.

That's fine if you have 360, we dont.

Neither do we. It connects to our local Exchange server fine from LAN or offsite over the net via our webmail url...

I think they updated the app to support this recently. When we originally trialled it yep, it could only connect to 365, same as the Win8 Mail App, but since Win 8.1 released the iOS OWA app and Win8 Mail App have both been updated to connect to native Exchange servers etc.

Do you mean the app or web?

Just tried again, it's not having it. We have Exchange 2010

Still looking into this, need a way of showing our global shared calender on mobile devices, BlackBerry, iOS and Android.

I've got an app called LookeeLoo on my iPad that can read shared calendars. It is very basic (and a bit flakey) but does the trick...

Not possible out the box as far as I am aware.

Set up calendar publishing, and subscribe to the calendar?

http://www.stevieg.org/2010/11/shared-exchange-calendars-on-ios-devices/

So you'd need to send out all the links periodically and the end user selects the ones the need.

We're definitely using OWA for iPad with Exch2010 & 2013 hosted onsite without any issues... but as an alternative...

If you've got a web server handy upon which you can drop a quick pile of PHP you can use https://github.com/jamesiarmes/php-ews

Save the below as calendar.php somewhere publicly accessible on the server, then bash a link to webcal://your.website.add/pathto/calendar.php - click the link on any device supporting webcal:// protocol, and you'll get the prompt to add it into whatever the default calendar app is.

Obvs change variables at the top, and $mailBox->EmailAddress...


$host = 'your.exchserver.co.uk';
$username = 'areadonlyuser';
$password = 'theirpassword';
$from =  date('c');
$to =  date('c',strtotime("+2 years", strtotime(date('c'))));

$mailBox = new EWSType_EmailAddressType();
$mailBox->EmailAddress = "[email protected]";
$request->ParentFolderIds->DistinguishedFolderId->Mailbox = $mailBox;
       
$response = $ews->FindItem($request);

We have several links available to our users which all provide the same calendar...

For webcal users (iOS & OSX support natively thru Calendar.app, Windows users via Outlook installed or another webcal associated client, Android & Blackberry via plethora of iCal / webcal client apps), a link to the above script.

For gMail users (this is probably what Android users will end up going for), https://www.google.com/calendar/render?cid=webcal://www.yourwebserver.co.uk/rss/calendar.php&safe=vss (which passes the webcal protocol link directly to Google Calendar, giving google account holders the chance to subscribe through Google's systems, rather than needing to give them instructions for manually adding the URL).

For our OWA users, https://our.mailserver.co.uk/owa/[email protected]/?cmd=contents&module=calendar&view=monthly where [email protected] represents the email account tied to the shared calendar in question.

Anyone who has subscribed in OWA for desktop, when they login to OWA for iPad (the app) or your OWA URL via Safari, any calendars they've already subscribed to will be there by default. OWA for iPhone apparently still only connects to Office365.

We also have a separate set of links that share our exams calendar, and another which just covers term-dates, and another which just covers public events, as well as the main links above which essentially provide all of those in a single calendar.
