this seems to be not working on newest 365 mail accounts. wich seems to need oauth2 authimapsync
i have been reading the github related to this, and seems to be failing for some (or they haven't been able to do so correctly). sadly i failed too, so wanted to add it to the thread since it's the thread i found when looking information realted to it.There is a new version since 2021 which does support oauth2 at least partly.
Can still be tricky though even now.
Outlook client won't work either, since, it does not allow you to add 2 times the same email (with different configs), Thunderbird does allow that, so indeed is an optionYes, it does not work for everybody yet, investigation is still ongoing.
DA is not the only one having issues with this, all panels do.
At this moment, a free way is to create the account first in DA, then with an e-mail client like Outlook or Thunderbird, install both email accounts as IMAP accounts and then drag all mails from one account to the other one. Takes a lot of work, especially with a lot of clients.
Until Imapsync is fully compatible, probably the only other way is to use a paid tool.
