How do I change my email address?

[#1]

What do I need to do in Plusnet & Greenby to change my email password?

I use Thunderbird to download email onto my desktop and webmail to read them (but not download) on my tablet.

The accounts are in my name but my wife also has a Plusnet email account and I don't want to affect that.

As you mention Greenby I am assuming that your email has migrated to Greenby,

Managing the passwords depends on which email servers you are using.

If you are using email servers that are both hosted by Greenby ( e.g. for force9 )
changing the password in the Greenby portal will do the job.

However if your SMTP server is hosted by Plusnet ( e.g. relay.plus.net ) you will
also need to set the same password in the Plusnet Members Center.

Greenby Management Portal :  https://greenby.com/

Plusnet Members Centre, Manage Email :  https://www.plus.net/manage_my_mail/

I am using relay.plus.net for the SMTP but I can't see where to change my password in  https://www.plus.net/manage_my_mail/

Also where do I change the password in Greenby?

Seriously !

Plusnet : tab Mailboxes >>> edit

Greenby : email >>> right hand side 3 dots >>> Change password.
