  Hi Serge,
  
  In answer to your first question "So does in cohexistance scenario, the local support@mydomaine.com mail box can be deleted totally and if not present it is automatically forward to Online, or does it have to remains also locally ?".
  
  Co-Existence provides the ability to move mailboxes in a controlled manner. So once you have gone through the process of enabling the Online account and moving the mailbox data it is recommended that you delete the local mailbox for the user - and as the Migrate to Microsoft Online Services documentation (see link below) states " as soon as you are comfortable with Exchange Online".
  
  If you have used the Microsoft Online Services Migration Tools to help with the migration (definitely recommended) then you should use the Delete Mailbox Wizard to remove the local mailbox(es). To quote the documentation again "This wizard deletes the local alternate recipient and disconnects the mailbox. For each user, it adds the user's Exchange Online target address as a forwarder on the local Active Directory account, so all mail addresses to the user will continue to be forwarded to Exchange Online".  The target address being user@mydomain.microsoftonline.com .
  
  For more detailed information see Pages 30 through 32 of the following link:

  To answer the second question:
  Then when synchronisation occurs every 3 hours, what is exactly gets synchronised ?
  This refers to the Directory Synchronisation - attributes needed from Active Directory are sunchronised to Microsoft Online. Therefore any changes made in your local Active Directory synchronise one way up to Microsoft Online using the Directory Synchronisation Tool. So until you have migrated all of the email mailboxes and the co-existence period has completed only make changes to user accounts using AD Users and Computers on the local Active Directory. The default replication time interval is 3 hours.
  
  Again more detailed information can be found on Pages 32 through 35.
  
  Hope this helps
  
  Regards
  
  Mark

  Thanks for your reply.
  Sounds clear what is happening then.
  
  Now still a guess.
  In my local excchange I have still some users which remains local.
  
  1 - What happen if a local user will add a new contact , will I be able to gets this new contact when synchronistaion occurs ?
  2- In an other hand, I wan to share an online user calender with a local accoutn calender how it will happen ? the idea is that my manager for instance remaining local would like to know all the time a view on my MS online calander in order to share meeting and plans for dates, how this is performed ? in similae way as Local outlook where you need to share you calander with a user by entering his email adress ?
  
  regards
  serge

  Hi Serge,
  
  With regards to your question about contacts - it depends where your users add them. If they are added locally to their personal Outlook Address Book then no, they won't be synchronised. If however they are added to your local server as a Contact then the next time sync runs it will sync upto MS Online. Try it as a test.
  
  With regards to your question over calendars - I've replied to a similar thread in the Exchange Online forum.
  See >> http://social.technet.microsoft.com/Forums/en-US/onlineservicesexchange/thread/76117da4-5cef-4acf-96d3-c79c63dbaefa
  
  
  Regards

  Mail will flow to your Online user if you have either:
  1) A Mailbox User on-premise with a Contact acting as an "Alternate Recipient" and forwarding mail to Exchange Online
  2) A mail enabled user that represents the user as an account but has a TargetAddress pointing to Exchange Online.
  
  If you migrated (and set forwarding)  using the Migration Tools, then you can select the same user in the Migration Tools and choose to "Disconnect Mailbox" and that will convert the user to a mail-enabled user, remove the mailbox and preserve mail forwarding to the cloud.
  
  With regards to your second question about DirSync: Every 3 hours, it will replicate the changes that happened during those three hours. So, if you added a user, changed two properties on another and deleted a third, these will be the events that DirSync reports to Microsoft Online and then they will happen there too.
