If you use any Exchange accounts in eM Client, you may have encountered an error message that has repeatedly popped up in the Operations window over the past few weeks.
This was caused by a change that Microsoft made on the Office 365 servers. Because we have no control or heads up over such changes, it took us a while to find a way to work around this problem and implement the fix in a new update.
Please download updated version 7.2.38682
