We seem to be having an issue with the Office 365 Office Message Encryption (OME) for a couple of customers. They are properly licensed with Business Premium and AIP Plan 1 and have the latest version of the Office desktop (1812.11126.20196). The button has just disappeared. Recently, it's been upgraded from the previous envelope with red circle to the new lock icon. Yesterday, it is now either grayed out or the tab has completely been removed from the "New" message window in the "Options" section. It was working fine the day before. Not sure if this is related to the recent update of the Office client, but other customers with the same set up are not experiencing this issue. The current affected customers still have the ability to use OWA to use the Protect/Encrypt button or mail flow rules I created for a work around.
I have also tried using the Online Repair option, new Outlook profile, and uninstall and reinstall. These do not resolved the issue. Also, they do not have the AIP client software installed. I have not checked this out yet, has the other customers with the same licensing and set up or working as expected.

I have the same issue. Latest version of Outlook too and on business premium as well as p2 license for Security. Shows up for others but not for me and im the admin. One hint though, is I noticed if you go log into office365 then go to Subscriptions area (https://portal.office.com/account/) mine says Business Essentials which is what I used to be on. Not on that now. I suspect that's the issue.

More than likely you have both subscriptions added to your user, Business Essentials and Business Premium. Remove Business Essentials and then check to make sure that all services are turned on under the Business Premium license. If you had Business Essentials prior, you must have gotten your Office install from some other means. Office 365 Home and Student does not support the feature in Outlook. Check your version of Office.

I have the encrypt button now. As it turns out similar to what you said, my version of Office was wrong. I didnt realize it has to be version you download from office365.com in order to work or at least in order to work with the least hassle. The version I had was an volume license install.
Now that the encrypt button is showing and I can send encrypted emails to internal recipients just fine, when I send to external receipts using the "Encrypt Only" selection, the recipient (my gmail account for testing purposes) gets the email, gets the encrypted attachment but has now way to open the attachment. What I was expecting was for the email the recipient gets to include directions on how to use a one-time passcode to read the encrypted email.
I have a ticket open with Microsoft on this, did screen step recording and sent to them but been waiting on a reply. Thanks for your help.

Did you receive a resolution for this issue? I'm running into this for a customer who when they send out the encrypted email, it has no body. The attachment will open fine in outlook, but nothing will open in google. It's like it's missing the body of the message.

@crankinadmiralI'll have to give this a try...we use a volume license version as well and the encrypt button is there for everyone except this one user. Though it could also be because that user is also the only one still running a VM...

Enable Google and one time passcode. Use PowerShell to check the OME settings.

@Alex MelchingI found this issue to be due to licensing. after trying to troubleshoot why some of my users had the encrypt button in their outlook while others did not, a quick note from Microsoft confirmed what was an oversight. even though you can activate and enable OME for OWA for all users, to do so with those using local outlook client, they must have at least an E3 license assigned to them.
Note: Microsoft 365 Message Encryption is part of the Office 365 Enterprise E3 license. Additionally, the Encrypt-Only feature (the option under the Encrypt button) is only enabled for subscribers (Microsoft 365 Apps for enterprise users) that also use Exchange Online.
this note is under the section “Encrypt with Microsoft 365 Message Encryption"

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-subscript...
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=...
The page you reference does not have updated information.

@Alex Melching First you have to have correct license. If the encrypt options button is not listed, go to Outlook trust center, email protection settings and put enable Encrypt emails. After that, there should be encrypt options visible in outlook.
