I earlier filed an issue at github/XPrivacy, issue 2253:
| I've been using XPrivacy for a few years, but this issue is new, possibly triggered to an update to the latest
| I found that my calendar has stopped showing any entries, and then I noticed that the Exchange account has
| disappeared. Eventually, I managed to track the problem down do XPrivacy.
| With XPrivacy disabled/removed, I am able to create an Exchange account and use it normally.
| From there, after installing/enabling XPrivacy and rebooting, the Exchange account has disappeared (and
| doesn't come back after removing/disabling XPrivcay).
| Trying to set up the Exchange account with XPrivacy enabled, there's a message that Exchange services have
| stopped before setup is complete.
| I'm not sure there are any settings I could change because the software only shows restrictions for user apps,
| not system apps.
| Android version 4.3 (latest available for device)
| Device Sony Xperia SP (C5303)
| XPosed Framework app_process 58/XposedBridge.jar 54
| XPrivacy 3.6.19
to which I received the following response by M66B:
| I am quite sure this is not caused by a bug but by a restriction.
| I don't know which one, however.
| Your best bet is to ask for help in the XDA XPrivacy forum.
So I hope I found the correct forum.
