We are aware of a Microsoft posted outage for Exchange online. You can see this is being reported in several places. https://www.bleepingcomputer.com/news/microsoft/microsoft-exchange-online-outage-causes-email-failures-auth-issues/ 1. If you are emailing 1Stream, it is likely your messages are not reaching us for sales, support, etc. Our systems are online but email is likely not being deliveed. 2. If you use M365 for outbound email from your 1Stream account for things like alerts, voicemail-to-email, etc it is likely that those messages are not being sent.
