Exchange calendar not allowing me to send meeting responses

Hi

Been using iphones with our SBS 2003 exchange server for a while now. I've gone from a 3G with V2 software to my current 3GS with 4.1. I think that the problem started when I got the 3GS with 4.1.

Basically, everything works with exchange apart from one very annoying thing.

If anyone sends me a calendar (meeting) invitation, it alerts me on the phone, allows me to see the meeting, but if I press accept, the phone ALWAYS says ' Calendar Invitation - Your response to the invitation cannot be sent'

It then deletes the meeting from the phone!.

Everything else seems to work, mail push, sending mail, creating contacts syncs with the work servers, I can also send out meeting invitations from my phone. It's just I can't respond to meetings i've received.

Anyone else have this?

Thanks

Andy

I had the same problem.. It was driving me nuts, but I was able to get the error to stop popping up by doing the following.

First off you need to know which calendar you replied to that has the updated meeting.

Once you know that go to Settings > Mail > Accounts

Select the Account that is having the issue

Switch the Calendars sync setting off and delete all from your phone

After a couple of minutes have passed turn it back on

Good to go after that. This is still definitely a bug but that's a work around to get the darn message off your phone until they fix the root issue.

Cheers.

A few users within the company I work for had the same issue. It turns out that they did not have Outlook Web Access. Once they obtained this, they were right as rain and could accept any invites without this error appearing.

@ MJscott,

The users I have with iPads, Exchange 2007 and are affected (Boss + Delegate) do have webmail enabled.

LarsC,

Thus far nothing I'm afraid. I'm VERY annoyed that Apple Text support suggested I pay $600 for Exchange support (from Apple) yet with no word IF it can be resolved. Not the kind of expense I can bring to my manager/director to warrant paying for.

At the moment I brought the situation to the System's Engineer of Apple regional HQ (Markham ON) yet thus far its not supported. Thus far - Apple is currently tight lipped but this is a real request by so many corporations finally imbracing Apple and iOS this needs to be implemented.

Through testing up to iOS Beta 7 ... any action to Deny works (from Delegates Cal/Mail).

should I enable the executive's Outlook to receive invites THEN accepting on Mail/Cal on the Delegate's iPad works - BUT this is not a solution as the executive's email will be flodded with over 25 mail calendar acceptances/denials/suggestions for new times. We're a global outfit so this means about 15x 25+ users per month ... not a lot of fun.

ActiveSync is enabled. I'm not sure what else to do .., OTHER than implement security settings from an ActiveSync profile (something we've used only from iPhone Configuration Utility 3.x; the current version).

It's taken me two years to get my agency to try Apple/iOS and this one issue may kill it for years to come. I've tried every work around and suggestion to date and I'm still getting multiple invites from ten months ago to today. They just keep coming back like a bad dream. The only reason it hasn't been fixed is it hasn't happened to the executives at Apple. If they it did, they would raise this issue to the point of fixing it.

If you are having this issue and you have any other mail/contact/calendar accounts that are not exchange set up, try removing them (be sure you have a backup/copy of the information). I removed the one non-exchange account I had (readded a google account via ms exchange "google sync" instructions) and it resolved this issue.

I am running iOS 5 and had this same issue, couldn't respond to meeting requests, and just had a couple of updated meetings disappear from my calendar completely. I removed the offending non-exchange(activesync) account and it is working normally now. I am able to reply to meeting requests and updates show correctly. I have not added back my gmail account yet.

When re-adding the google account, you probably want to use these instructions...http://www.google.com/support/mobile/bin/answer.py?answer=138740

@MJscott

Thanks for your tip! A couple of our employees couldn't respond to Meeting Requests via their iPhone 4S. We enabled OWA (Outlook Web Access) and they're now able to do so.

Thanks again!

This resolved my problem. In my case I removed my company email account that was connected with ActiveSync. Thanks for posting the information .
