Hello Sue,
A warm welcome to the forums - sorry to read of your loss.
I think that there might be something of confusion here. The email will advise that either you are using more than 75% of the 1GB fair usage policy limit, or you have exceeded that limit. If the latter, it will also advise that unless you take action, the mailbox contents will be archived [off-line] by Plusnet.
The action which you need to take is to do some house keeping on the mail folders...
- Inbox - delete the "noise" emails which do not need to be retained
- Sent items - similarly delete those of no consequence, especially those which might simply have shared photographs or large documents, for which there is no need to retain a record
- Deleted items (trash) - doing the above, empty the deleted items folder
Webmail does not have an archive function, for if there was one, that would simply be moving mail around within your storage allocation ... which would achieve nothing.
I am not familiar with the Apple Mail program on a MAC; I use the same on my iPhone but I see no concept of local folders. Most email programs have the concept of local folders. These reside solely on the individual device, in to which you can move emails which you want to retain from the Plusnet (or any other) mail service. It is essential that you have a good back up strategy for such folders, for if you do not and anything happens to your MAC, they will be lost forever.
Hope that helps.
