Ok folks,
I want to point out that there is an uninstall case that we just uncovered that people may hit. Although the cases where customers have had to uninstall this particular version of Rollup 4 is low, I want to share this with everyone.
- On install, the EWS Web.config file is installed with 'placeholder' information that is modified outside of the MSI (installer) while Exchange Setup is running.
- When we uninstall Rollup 4, the EWS web.config (example: D:Program FilesMicrosoftExchange ServerClientAccessexchwebewsweb.config) file is restored to the RTM version without the post-processing.
- On startup, EWS tries to read it and does not function properly.
For those who encounter this condition, the fix is to open the web.config file manually and Find + Replace the information it needs. I should have the blog updated with the official info shortly with ways to detect this and the steps to fix this.
I will have more later this evening as I write up the official blog post.
