Current behaviour of Axigen is to answer incoming meeting invitaions always with the primary email addres of an account. It does not respect the email the invitaion was send to.

Due to this behaviour we often get invitated twice to meetings without anyone can do anything against it.

Example:
1. primary email: flastname@... , official email: firstname.lastname@...
2. Other external user sends invitation to firstname.lastname@...
3. Axigen automaticall answers invitation with flastname@...
4. Other Mail server (mostly Exchange) adds flastname@... to the invitation list tooo
5. Now all changes to this meeting/recurring meeting are send to fistname.lastname@... AND flastname@...

This is very important as many users might have a different (internal) primary email than the one they use day by day. For example the LDAP account name (that is used as primary mail) is most of the time not the name officially communicated as user email address (e.g. firstname.lastname@...)
