The University of Nottingham just enabled Outlook's archive feature:
“To keep your mailbox lighter and faster, emails that are older than 90 days are automatically moved into an online archive. You will find your old emails in the following folder:
- In the Outlook app, the folder name is: Online Archive – [Your Name]
- In the web version of Outlook, the folder name is: In-Place Archive [Your Name]”
In practice this means I can no longer access any emails older than 90 days in Thunderbird and there does not appear to be an option to download the In-Place Archive.
My question: What can I do to get this archive into Thunderbird, or to at least retain an offline copy?
I tried following https://stackoverflow.com/questions/28005516/can-you-use-davmail-to-access-exchange-archives and https://unix.stackexchange.com/questions/179034/can-i-view-my-microsoft-exchange-online-archive-via-davmail-in-thunderbird but that didn't work. (In particular Thunderbird flat out refuses to add an account with the same server and username...)
