MS Exchange and IMEI on SailfishOS 2.0

Well, i actually bricked and factory-reseted my phone because of stupid me, so I recreated my Exchange account, and can't tell if you're right. I'll check that tomorrow and will let you know.

I'm having the same issue. Syncing stopped working after updating and recreating account doesn't work anymore.

Same problem here. I set pin code and device lock code but I cannot add the account again. It has been working all the time with Jolla but now with 1.1.9.28 it stopped syncing. Strange.

Please also check that automatic time update is enabled. Clock skew could also explain that.

Other thing that could explain that behavior is poorly installed certificates. I had that issue once. Can you post the output of the following command here? Developer mode and terminal required, of course:
curl -kIv1 https://exchange.server.here.com

I get the following with server identifications redacted.
