If you are attempting to Set Up eDocs and need to create an Adobe Admin, but your Outlook email address is already associated with an Adobe account, creating an Alias in Outlook is a great workaround.
Note: You must be a Firm Admin to create an alias.
To Create an Alias in Outlook:
In the Admin Center, go to Users → Active Users.
On the Active Users page, select the user and then select Manage email aliases.
This option will not appear if the user does not have a license assigned.
Select + Add an alias and enter the new alias (e.g., liscioadobe@smithcpa.com).
The alias must end with a domain from the drop-down list.
Select Save changes.
Allow up to 24 hours for the new alias to populate throughout Office 365.
How It Works:
The user will now have a primary address and an alias.
For example, mail sent to john@smithcpa.com and liscioadobe@smithcpa.com will both deliver to John's inbox.
Troubleshooting:
Error Message:
"A parameter cannot be found that matches parameter name 'EmailAddresses'"
This means the setup process is still completing.
It can take up to 4 hours for an alias or newly added domain to finish setup.
Wait a few hours and try again.
