Encrypt button disappearing from Outlook
Hello, that is absolutely not true. You do NOT need to have an Enterprise level license or subscription, but you do need supporting licenses and/or add-ons. When I started this post, that was the cause of the issue because after an update only Enterprise licensing (and O365 ProPlus) offered the Encrypt button and was quickly corrected when many SMB (with supporting licenses) users reported the issue as well. Supporting licenses: https://docs.microsoft.com/en-us/microsoft-365/compliance/ome-faq?view=o365-worldwide#what-subscriptions-do-i-need-to-use-the-new-ome-capabilities
Newer tenants also have certain OME and IRM settings already enabled where as older tenants that may have not used OME before do not have turned on and you should go through the OME and IRM settings and enable newer features if necessary. https://docs.microsoft.com/en-us/microsoft-365/compliance/manage-office-365-message-encryption?view=o365-worldwide
The page you reference does not have updated information.
"Microsoft 365 Message Encryption (Information Rights Management) - To use Microsoft 365 Message Encryption, the sender must have Microsoft 365 Message Encryption, which is included in the Office 365 Enterprise E3 license."
It's not just limited to Enterprise E3.
