Invitation alerts on Exchange

My iPad2 is set up to use my Exchange account for mail and calendar, and I have the invitation alerts turned on. I am getting some pretty strange invitation alert messages however. Today when I got back to my desk the iPad said I had 262,144 invitations! No, I am not really that popular. In reality, I had 2 new invitations. What's the deal? I've never noticed this behavior on my iPhone4 which is set up to use the same account.

iOS 4

I had the problem of an escalating invitations count on an Exchange account.

I turned off calendar synching on that Exchange account and then turned it back on. Invitations continued from where it left off.


I deleted the account, upgraded the OS to 4.3.2, took a backup of the system and wiped it clean. I restored from the backup.

All appeared OK for several days and the number of invitations began to grow from 2.

After about 2 weeks, my current count is 544,210,944.


At this point, I do not see a solution. By reducing the frequency of synching, we may can reduce the pace of growth, but that doesn't solve the problem, only slows it down.


I have iPhone with no problem.

I am also having this issue with my ipad 2. I have Exchange and a google calendar configured in accounts. Most of my cal invites come from exchange, so last night, I turned off the exchange calendar switch, 'accepted' the deletion of the calendar. Then today, I turned back on. I soon received a message that I have > 1 billion invitations. I just sent a new invite from my google cal to my exchange cal to try and recreate the alert for a screenshot, and now it is down in the hundreds of millions. specifically 537,395,200

I am also having this problem on an iPad2 that I did *not* upgrade from an iPad1. (I started a fresh thread before I saw this one.) I am using iOS 4.3.1, and my count is currently holding at 8,388,608 invitations. I didn't update to the latest iOS because the release notes made no mention of any iCal fixes, and others report that it didn't fix the problem.


Does anyone know if a bug report has been logged with Apple about this?


EDIT: I just noticed the suggestion above to delete and re-add the account. I just did this, and now I have 16,777,216 invitations! I am soooooo popular!

So I called Apple, and as usual their support was less than useful.


They informed me that they "guarantee" that the problem is on our Exchange server. There must be unresponded to invitations in the user account with the problem.


I am skeptical that this is the case, although I haven't been able to track down the user to confirm that.


The main reason I'm skeptical is that if like our unfortunate friend above he actually has 176 Million invitations, his mailbox would be 167 GB in size (assumming, that each invite is one KB, which is actually low, and he had no other messages in there).


I don't know how much Apple's exchange servers allow for a mailbox size, but I know our company doesnt allow 167 GB per user (more like 200 MB).


I'll keep everyone posted.

I have the same issue, upgraded from iPad1 to iPad2 and have begun seeing this issue pretty much immediately - it doesent look like an Exchange issue to me to be honest, I have a few devices sync'd to the same mailbox and none of the others are displaying this weird behaviour. Seems to be isolated to iPad2's also, its not affecting my iPad1 connected to the same mailbox...

Hi all--


I have a similar problem going on. But I did notice that the invitation number is ALWAYS divisible by 1024 (feel free to prove me wrong if you have a counterexample.) Which happens to be the exact number of bytes in a kilobyte...


That would make me pretty sure that we're dealing with a code problem in the iPad itself...


Any motion from our friends at Apple?
