Recipient is unable to click on the calendar invite that was sent out.

It kicks out an error which I will list below as ERROR MESSAGE EXAMPLE


ANSWER - 

https://www.quadrotech-it.com/blog/what-is-the-x500-email-address/#:~:text=The%20X500%20email%20address%2C%20or,this%20trick%20still%20applies%20today.

Method 1: Active Directory Users and Computers (ADUC)

If you just have a few accounts to change or want to investigate the issue further, you can use ADUC to do this, with Advanced Features Turned On.

  1. Log in to a computer with Active Directory Tools Installed
  2. Launch Active Directory Users and Computers (ADUC)
  3. Click on View and check “Advanced Features”

X500 Proxy Address Screenshot

  1. Navigate to the user account – sadly you can’t search to view attribute editor
  2. Choose the attribute editor tab
  3. Scroll down and select ProxyAddresses
  4. Click Edit



X500 Proxy Address Screenshot

  1. You will now see a list of all addresses
    1. SMTP in caps is the users primary SMTP
    2. smtp is lowercase is the user’s secondary SMTP addresses
    3. X500 / x500 does not have much function for a primary/secondary address
  2. In the value to add section, add the address. We collected the users Exchange Legacy DN in the script above, or you can get it from the NDR Email the organizer is getting.
    1. Start with x500 or X500, keeping in mind only one address should be with a capital X
    2. Colon (:)
    3. And the Exchange legacy DN next, with no space. This starts with “/o=”
    4. Example:
    5. x500:/o=ExchangeLabs/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=0511b2015ac3521f8355f08ca5be1af1-MIWE TestAA
  3. Click ad and then OK
  4. wait for replication and attempt to update the calendar invite again – the issue should be resolved
