Subscribe to subfolders of shared mailbox
Previously, I have been using Evolution via Gnome Online Accounts connected to Microsoft Exchange. This has been working fine, and I was able to subscribe to our company's shared support mailbox, and the subfolders within said account. Since NTLM access is no longer possible, I have removed my Exchange account from Gnome Online Accounts and added it directly to Evolution via oAuth2 authentication. This has worked fine for my own mailbox. However, I tried subscribing to the shared mailbox's Inbox and its subfolders, having the option "include subfolders" enabled. However, this does not seem to work. I can only see the Inbox, but not the subfolders within said Inbox. I tried creating the folder that I knew existed, however it would just give an error stating that said folder already exists, without actually showing me said folder.
I have already tried using the "manage subscriptions" option, but that´s just giving me a "There are no public folder servers available". Any ideas on how to get my subfolders to show up, so I can effectively continue to manage our company's support box from within Evolution?
