Issue with Outlook 2013-Notifications from published Calendar

Question

Hi Every body,
I'm setting up for my little company published calendars on a Webdav servers (i'm using IIS on a 2003 server and Office 2013).
Publishing calendar works fine so far.
But i'm facing up a real issue:
When a user add other's published calendar the first user will also recieve Calendar alerts (appoitement alerts) from the added calendars (others users). Since i have arround 10 Shared calendar it's very frustating for users to be disturbed because of other's
calendars.
I've been looking for a way to disable those alerts but i can't find a way. on the Outlook settings. 
(I also want to keep personal alerts up)
Please help me i'm becoming very frustaded.
Best regards 
Fred

Well that's not the same calendar in outlook it's a realy different calendar that you get from your webdav server.
so i remind the whole process just to be clear =)
10 differents users are publishing their own outlook calendar on the webdav server.
So there is 10 differents ICS calendar into the server. But remember ICS calendar are copy from the originals calendar they need to be kept up to date.
Then some users pick the calendars they need from the server and add it into they own outlook.
in this way it appears as a whole different calendar in outlook.
When you publish a calendar from outlook,(right clikc onto the calendar => share => publish into webdav server) your have 3 ways to publish it, 3differents options. I can't translate properly since my version is in french. But just to make it short:
1)
The first way to publish it is not useful in my case because it doesn't provide enougth information into my ics calendar. about my appoitements.
2)
The second option looks good to me because it does'nt provide VALARM option Inside the ICS calendar.
But  with this option the message inside appoitements are missing.
3)
The third option Include everything about the appoitement (and the VALARM). An thats actualy my problem.
And Yes i'm editing the ICS file that what make me understood how the whole process works.
