@server.camp I think I remember reading a thread a while back that the case import does not work from MS Exchange inboxes. I tried to search for you, but didn’t see anything in history. I pretty strongly remember there was an issue with MS Exchange inboxes. If someone else has case management working with MS Exchange maybe they can chime in and cofirm it either does or does not work.
@pstewart@rsp Thanks for your research on this! I can confirm that fix is included in the version I’m using (8.8.0). Weirdly, case creation does actually work sometimes, but not reliably. I could figure out a pattern yet.
Also, I’m not actually using Office 365, but an externally hosted MS Exchange 2019, but it might come with similar problems.
