"Sync & Storage" option missing for Office365 account using OWL for Thunderbird

more options

I have configured an O365 account in Thunderbird(v102), macOS using the OWL Plugin, and want to download all the messages(along with attachments) on the server. The common answer I found on the forums is to go to the "Account Settings" > "Sync & Storage" section for the account you want to download all messages.

I can see this option for my Gmail ID, but not for my Office 365 ID!

It certainly has not downloaded all the emails, evident by my Profile Folder's storage utilization. Is there any way to download all of those emails, locally!! I have tried : - Going offline > Then selecting download everything before going offline. - Selecting "Don't delete any messages" under "Local Folders"

You should ask the owner of the Owl add-on. There is a support email address. https://addons.thunderbird.net/en-US/thunderbird/addon/owl-for-exchange/

If you do get a response, please post it here as well.

Thank You for the reply :) Will certainly update this thread once I have any clarifications. I have sent an email already & specifically created this thread to document my findings / get insights from anyone who had been on the same path!

Btw, as of now, for anyone who stumbles on this, I resorted to booting up a windows VM, installing the official Outlook app, then changing the number of emails to download under "Account settings" to All Then creating an archive by "cleaning up" tools. This basically transfers anything before the specified date into a single local .pst file which can be kept open in Outlook. But certainly not the ideal solution! And would be great if TB supports something like that.
