Use aliases on the mailbox on the other extensionsI have a system owner assigned.. but I cannot have unique email addresses for the users.. some are 1 person/multiple extension users with one email account.. is this going to be an issue? the upgrade is still grayed out.
I believe on v20 the web client is disabled for the user, without an email address. And in the user settings it's a required field in terms of saving changes.does EVERY extention need an email address? i..e. can any be empty?
