I'm having a bit of trouble getting e-mail aliases to sync with Office 365 when using Azure AD Connect. I have managed to get all the on-premise AD accounts to sync with Office 365 but cannot for the life of me get the e-mail aliases added. I have read countless forums that say edit the "proxyaddresses" field for each AD user account with "SMTP:email@domain.com" for the primary address and "smtp:email@domain.com" which I can do, however when I run the resync aliases are simply not synced. I can confirm the aliases I'm trying to add are verified domains within Office 365. Has anybody experienced this before? I've added a UPN for one of the domain names as we were using domain.local previously, I have set each user to use the UPN using the IdFix Tool which again has all worked fine but still aliases don't seem to be syncing!?
Any assistance would be greatly appreciated.

You have to include those extra domains in your configuration for Azure AD Connect. Re-run the wizard and there should be a section in there to add more domains.
