iCloud Calendar invitations not working

I migrated my MobileMe account to iCloud and calendar invitations are not working. When I create a calendar event and select an invitee an email is not sent to the invitee. I have tried sending invites from iCal on my MacBook Air, iPhone, and iCloud.com with no success. I tested by creating a new iCloud account using a different Apple ID and still no luck. Anyone else having this problem?

This is a very old thread but for the last few posts here is the thread you are looking for with current information.


Re: iCal will not send if location is added to event


Since late November/Early December 2016, many people have not been able to send event invitations when the add a "suggested Apple Maps location" which seems to be blocking the invitation. Read the thread above for other people who have had the same issue.


As i said, this has been happening to me since late November/Early December.


I was manually adding some December/January Calendar events (adding suggested Apple Maps locations) and the inviting a couple family members. After about three invites to events, the invitations stopped going through. One other did go through but it had "TBD" as the location.

Fast foreward: Tonight I removed the suggested Apple Maps locations and left only location names and the invites began to flow! I was able to reproduce it as described above and below in every instance.


1. Both macOS Sierra & iOS 10.2 Calendar apps are affected in my case.

2. It only has happened to me with using suggested Apple Maps locations.

3. I have had no problems with Emojis nor adding notes, only with suggested Apple Maps locations.


I was able to create an event then invite without a location on macOS. After accepting I could modify it on an iOS device and add a suggested Apple Maps location. The the invite would then update to the suggested Apple Maps location for the invitee.


I wonder if my initial action of sending multiple event invites in a short time triggered some anti-spam block in iCloud servers? This began around the same day Apple announced it was going to start actively blocking spam invites. My hope is that I have not been put of some spam list.


I submitted a bug report to the Calendar Engineering Team. It was quick and simple. Hopefully they will find the bug/spam filter issue and fix it soon.

I am having major issues with iCloud (web and desktop calendar app) not sending invitations out to invitees using my iCloud account. I'm this close to switching to Gmail for good, and I so don't want to.


Unfortunately you cannot change your primary Apple ID email address anymore, only the alternate email addresses. So sorry to say Alfabet's solution doesn't work, at least not at this point.

I was having a similar problem, but it went a little deeper. My wife could not receive calendar invites at her Gmail address because her Gmail address is also her iCloud login. My Gmail address is (was) also my iCloud login. I have it working now with a fairly simple workaround. Here are the steps I took:


-I changed my iCloud login to a different e-mail address (outlook.com) and that didn't solve it.

-I created an entirely new iCloud login, but she still could not receive invites

-I tried sending invites to other e-mail services, like Yahoo, and those worked fine

-I tried sending to her throwaway Gmail address and that worked fine


OK, so at this point it definitely appears to be related to the fact that her Gmail address was also her iCloud login. The way I saw it, there were three solutions. Either she had to change her iCloud login, or use a different e-mail for calendaring, or I had to stop using iCloud calendar.


I like iCloud despite its quirks so I didn't want to stop using it. While she might be willing to change her login because she loves me, that's not really practical because there are sure to be other people out there that have the same issue. Asking all of your friends, family, and colleagues to change their iCloud logins because you can't send them calendar invites is kind of crazy. Then I remembered that Gmail allows modifiers for e-mail addresses. You can put periods ( . ) anywhere in the address and/or a plus symbol ( + ) at the end plus a combination of characters.


-So if her e-mail was janedoe@gmail.com, and that was also her iCloud login, then I can send the calendar invite to jane.doe@gmail.com or janedoe+calendar@gmail.com or jane.d.o.e@gmail.com and she'll get the invite.


The trick there is that those other e-mails addresses are not, as far as Apple is concerned, her iCloud login, but they are, as far as Google is concerned, her e-mail address.

I followed all of the steps and tried iCalendar again. I didn't get the invites until I deleted my iCloud data from my phone (Settings>iCloud>Delete Account>Delete>Delete from My iPhone). Once I went through the delete process and re-added my original Apple ID, I received all of the iCalendar invites that I hadn't been receiving.


alfabet, you are a flipping rock star! Thank you for solving my iCalendar invite problem. No longer do I have to check my iCalendar invites on iCloud or my iPad -- I can now use the iPhone 5S that should have worked after programming right out of the box. ...Apple misses the mark yet again!

I had the same issue as many in this thread. Calendar sharing invitations were not being received in my wife's email account (gmail). My solution was this:


1. Delete the original iCloud calendar (I had very few events in this particular calendar).

2. Create a new iCloud calendar in iCal.

3. Share.


Perhaps the old iCloud calendar was corrupted somehow. By creating a new iCloud calendar, the sharing issues resolved. Obviously, this is not an ideal solution if you have lots of entries in your calendar.
