Hi, I’m the Notes Mail UI Designer, Margo Ezekiel. I represented you and your feedback at a meeting we held to determine if mail recall should be on or off by default. Based on the responses to this blog and Ed Brill's blog, we decided that Mail recall will be ON in version 8.0.
We will revisit this decision again in 8.0.1, so if you have good or bad experiences with the default setting for mail recall in 8.0 please feel free to let us know about it, and to recommend a change to the default. This was a tough call. There were customers on both sides of the fence, with many strong feelings and good arguments. As a team, we wanted to keep the client and server in synch, so it will be ON by default in both. I am pleased that we were able to collaborate with our community to make that decision. Thanks again for all the valuable feedback.
p.s. There was a blog entry previously saying the decision was OFF by default. This was a mistake in our information so I had to recall the blog entry :). The final decision is for the Mail Recall feature to be ON on both the server & client.
