Password required for Exchange Web Services

I keep getting this password prompt every 2 - 3 seconds.  It’s very similar to other questions on here, and a majority of the answers that seem to work for the problem seem to be “get the latest version”.  How do I ensure I have the latest version?

Go to Menu > Help > About and see what version you are using. The current released version is 7.2.36908. If you are not using that version you can download it from the Release History
