'A parameter cannot be found that matches parameter name 'EmailAddresses'
If you get the error message ' A parameter cannot be found that matches parameter name 'EmailAddresses' it means that it's taking a bit longer for Office 365 to finish setting up your tenant, or your custom domain if you recently added one. The setup process can take up to 4 hours to complete. Wait a while so the set up process has time to finish, and then try again. If the problem persists, call Support and they will do a full sync for you.
'We're sorry, the user couldn't be edited. Review the user information and try again'
If you get the error message ' We're sorry, the user couldn't be edited. Review the user information and try again.' it means you aren't an Office 365 global admin and you don't have permissions to change the user name. Find the global admin in your business and ask them to make the change.
What to do with old email addresses
A person's previous primary email address is retained as an additional email address. We strongly recommend that you don't remove the old email address.
Some people will likely continue to send email to the person's old email address and deleting it may result in NDR failures. Office 365 will automatically route it to the new one. Also, do not reuse old SMTP email addresses and apply them to new accounts. This can also cause NDR failures or delivery to an unintended mailbox.
What if the person's offline address book won't sync with the Global Address List?
If they are using Exchange Online or if their Office 365 account is linked with your organization's on-premises Exchange environment, you may see this error when you try to change a username and email address: 'This user is synchronized with your local Active Directory. Some details can be edited only through your local Active Directory.'
This is due to the Microsoft Online Email Routing Address (MOERA). The MOERA is constructed from the person's userPrincipalName attribute in Active Directory and is automatically assigned to the cloud account during the initial sync and once created, it cannot be modified or removed in Office 365. You can subsequently change the username in the Active Directory, but it will not change the MOERA and you may run into issues displaying the newly changed name in the Global Address List.
To fix this, log in to the Azure Active Directory Module for PowerShell with your Microsoft 365 administrator credentials. and use the following syntax:
Tip
Change Office Username
This changes the person's userPrincipalName attribute and has no bearing on their Microsoft Online Email Routing Address (MOERA) email address. It is best practice, however, to have the person's logon UPN match their primary SMTP address.
