Once in a while you may find yourself unable to send emails to users of Microsoft Exchange or Office 365 for no apparent reason.
Sending an email may result in an error being received of the sort that mail could not be delivered due to x or y reason, such as mailbox unavailable .. which in my case seemed really weird as I could send mails to the same folks through another mail system.
To cut the long story short, where everyone sort of blamed the sending server setup, the problem was the spam filter system of Microsoft, which was mistakenly blocking us, and sending back an irrelevant error.
All we needed to do was delist ourselves, by going to https://sender.office.com and following the instructions.
The hardest part was searching for this address, which apparently even MS support did not tell us.
I seriously think, the bigger the company, the harder to find the right information.
