Exchange 2010 Exchange Online coexistence

Copper Contributor

Dear All


I do not have experience with hybrid setups. I was wondering, is it possible to set up a hybrid environment between exch 2010 and exch online where there is only one mailbox in exch online?


Thanks in advance!

Kind regards

Well you surely can. If you want you can leave the Online mailbox user as online Only or Do a hard match or soft match to manage that user/mailbox from On Prem.


Refer the below articles for more details -



@Robin NishadThanks for your reply, I will certainly look into that!

I have started hybrid configuration but I get the error: HCW0000 PowerShell failed to invoke 'Get-SendConnector'


Any idea how to solve this?


Thanks in advance!!
