There are so many factors ...
Steve emailed me from his personal account, it was INBOXed, and there was no issue, but need to see it from the production system? Office365 is not normally configured to delete mail once accepted. In some cases it can, but those are per tenant choices. Aloha, Michael. -- Michael J Wise Microsoft Corporation| Spam Analysis "Your Spam Specimen Has Been Processed."

Still, there is a very good point between conscious decisions taken by you (or your IT team), which could include eg. to drop any email sent from Chinese IP address, and "a black box algorithm run by a third party made your emails disappear, and there's nothing to do about it" which is apparently the situation (and to make things worse, it somehow ends up being your fault ☹). Steve: are your emails getting into spam or disappearing completely? Are those non-technical recipients even looking at their spam folder? Ken: since your systems are apparently also flagging Steve emails as spam, maybe you have some hint for him? Kind regards PS: Just a few hours ago, I was feeling silly for stating the obvious «did you look at the spam folder?» Lo and behold that's not something they had thought in¹ and of course, after login into the webmail, there it was the missing email. ¹ since their client didn't show it The sad part is that the email system and the MUA were made by the same company. _______________________________________________ mailop mailing list mailop@mailop.org<mailto:mailop@mailop.org> https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fchilli.nosignal.org%2Fcgi-bin%2Fmailman%2Flistinfo%2Fmailop&data=02%7C01%7Cmichael.wise%40microsoft.com%7C721b825c506a4e8646e408d63f8c411a%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636766268962249031&sdata=ElkG0oMIeg%2FeN0P%2FgAjR%2BV5EAsUELC4EcFHOB3SzZDE%3D&reserved=0
