  11. Where are my Local Folders Stored?:
    • For people starting Thunderbird for the first time:

      By default, your local mail is stored on the network drive that stores your local profile (M: drive). Because this space is shared with the mail and K: drive we do not recommend moving mail to the local folders. You can create all the folders you will need or want right inside your IMAP folder. Please, do NOT change the local folder settings to something on the local hard drive (C:) without first discussing a back-up procedure with an IT Staff member.

    • For people importing files from Eudora:

      Your local folder will be kept in the same place that Eudora was storing mail previously. Please contact an IT Staff member to discuss a back-up procedure for this locally kept e-mail
