Using New Outlook on Windows for personal email, calendar, and contact management
I think it's also worth pointing out, Microsoft, that while there may be only a few (but growing) number of people adding their voice to this issue on this post, I suspect there are many, many more who have either not thought to try to search for a solution or do not have time or the inclination to add to this or any other post regarding this issue.
So the number of your customers you are anoying with this draconian method is, I suspect, much larger than perhaps you thinnk.
This is a daily problem for me, and at least 10 emails (that I actually need to read and know the sender is safe!) come up with the unverified sender flag, with no way of making them safe or accepting them to have access the the full email contents.
When this type of email is wanted and actually needed this is extremely frustrating. To say the very least.
