    Hi, are you sure it is related to the CPanel? We don't have this issue in past, but just recently there is an office /window update, in around 1-2 weeks ago, then the problem keep happen now!

    Can you double check if there is any error in your update?

    @Syedur,

    From what we have seen this issue is caused by a CPanel related change. Please contact your hosting provider and ask them to disable this change.

    Encountering this issue as well, no solution yet since we have no access to make these low level changes, but in my case it's due to an update to the software used by our e-mail provider.

    Here's some reference to the issue:
