Trying to archive onto NAS
Running TBird 140.12.0esr on a Macbook running Tahoe 26.5.2
I've got a decade of email in my mailbox which I find occasionally useful, and I'd like to shrink the storage I'm using.
I understand I can archive folders onto a NAS, but to do it I need to add a folder under 'Local Folders' so I can set it as the archive target.
My understanding is:
Open Account settings;
In the left pane, scroll down to Local Folders;
RIght-click on Local Folders - a should be prompted to 'add folder'
Add folder pointing to NAS folder'
Set Archive to 'other' and point to archive folder in Local folders.
My problem is that I can't get Local Folders to behave and let me create a new folder under it.
Which suggests that my instructions are incorrect...
