Outgoing emails suddenly going to recipient's spam folders

All my outgoing emails are suddenly going to my client's spam folders and they're not seeing my emails. I've tried to fix it through my email host support and have had no luck. They just suggested having them whitelist my domain. But since this is happening with all my clients, it's obviously not their problem for me to ask them to fix. I gave support three different emails where it was happening and they pointed out that they were all hosted with Microsoft. I don't know if that has any relevance.

Sometimes an ISP will bloc a whole other ISP too, if it's the source of too much SPAM.
