The maximum number of added message aliases has been exceeded.
The maximum number of message aliases on each computer is limited by the system hardware. You have reached this limit. This limit also affects the number of other domains you can specify with the Othdomains option of the Net Config Workstation command.
To find the limit for your system, see your hardware documentation or ask your administrator. To display a list of current message aliases, type NET NAME. To delete a message alias to make room for a new message alias or another domain specified by the Othdomains option, type NET NAME <alias>/DELETE.
