Changing the main email address for an account (Active Directory / O365 / AZ AD)
Hello, I've been trying to find a way to change an email address in O365 for a "shared" user account, lets call it support. The email assigned for that account is showing, lets say "mike@xxxxx". How...
It's not the "email" field you need to edit in your on-premises AD, but the proxyAddresses one. Alternatively, you can run the following cmdlet against Exchange Online PowerShell:

VasilMichev : thanks for the hint.... I've found that proxyaddress and changed that in on-prem AD. Waiting now for Azure AD Connect to sync and will check again what is the result.
Just FYI - when I check the "support" user in Azure AD, there are 3 fields under Contact info: email, alternate email, and proxyaddress. So I expect the proxyaddress will change, ...will see whether also email field will change.
