Hi Bourne,
On friday I am always out of the office, so that is why I have not replied yet.
I still need some help.
When I change the Display Name for example, this is synchronized well. Changing it back also, by the way.
You asked me to confirm that the email addresses have not been used in Office 365 as mailbox email addresses (including public folder mailbox) or proxy addresses. I don't know how to confirm this. All I know is that the users holds two e-mail addresses and I just can't set the right one as there default.
What if I remove the user in O365 but leave in the AD. Will it be recreated on the next synchronization and can I reattach the mailbox to this "new" account again?
Thanks in advance,
Jasper
