Sometimes meeting requests get the wrong organiser.

A secretary is delegate for serveral managers. She created a meeting in the calander of one manager, and invited serveral others (a few from outside the company, one from our company).

In the organisers calander all seems fine, but for some reason the "invited" manager gets the request in his inbox as a meeting where "he is the organiser". So Outlook does not put the meeting in his calander, because "he is the organiser", and he cannot respond (you guessed it) because he is the organiser. 

Does anyone know what is happening here? 

Check if attendee is an Iphone user. I've experienced this with IOS version 7 and some earlier version as well. Few IOS version has bug where is Hijack meeting invites and consider itself as organizer.

Unfortunately, the user does not have an iPhone, he uses a Windows system with outlook 2013 and a Windows Phone. He does not use an IOS device. 

Is there anyone familiar with problems like this on Windows Phone?

If i read the article correctly, the only way that could happen is through a IOS device, that is used by the person inside the company who gets the wierd meeting request.

Hi,

According to your description, I understand that the meeting request which create by secretary display wrong organizer, the secretary also delegate few manager.
If I misunderstand your concern, please do not hesitate to let me know.

Which Exchange and Outlook version are you used?
Whether the other manager is a invitee for problematic meeting or not? Can you reproduce this issue?
Also ensure all manager or just the organizer receive the meeting request because set Delegate receives copies of meeting-related messages sent to me.
Do you deploy SendAsItemsCopiedTo and SendOnBehalfOfItemsCopiedTo?

Firstly, please upgrade Exchange and Outlook to latest version.
Secondly, Please remove mobile device for testing.

Meanwhile, please ensure the configuration for Delegate permission:

we recommend remove redundant delegate permission to narrow down the issue.

Thanks

Hi,

I asked the secretary to notify me when she is able to reproduce the error. Up until now it did not happen again. 

For the parts that i am able to answer: 

Outlook 2013 (patched) server exch 2013. the options Delegate recieves.. .and sendasitems.. and sendonbehalf are not switched on.

The secretary is the only delegate for those managers.

Hope to be able to give more info, when the problem is reproducable.

Greetings
