eM Client [Exchange Web Services] an attempt to connect to failed

This message has started to come up recently every time I use the client. It has been fine in the past. If I press ignore, it works fine, but the error message eventually pops up again.

Any suggestions on fixing the error?

This is a copy of the error log:

It doesn’t address the cause of the error, but if it is working anyway and you don’t want to be reminded, you can disable the pop-up.

Menu > Tools > Settings > General > Operations Window. Untick Show window when an error occurs.

Brilliant, thank you Gary
