Mail1 Size is bigger than supported and JPG is not supported format

User1 should be mail3 only. .doc files are not supported, it is in the link eriksrocha posted. You can attach any file type to a protected mail. With one exception, protection policies are applied only on the file formats mentioned in File types supported by the Azure Information Protection client. OME does not support the 97-2003 versions of the following Office programs: Word (.doc), Excel (.xls), and PowerPoint (.ppt).

I think this type of encryption is no longer used today.

The max size for the OME encryption functionality is 25 mb and all file extension are not covered by the OME encryption. You can only encrypt docx files, powerpoint files and excel files. The following are the one supported, Old file extension such as xls, doc and ppt are not supported. Correct answer: Mail 3, since 40mb is too big and doc are not supported Mail 4 and Mail 6, since jpg are not supported.

According to the documentation this answer is still valid. Maximum size of email is 25MB and 97-2003 formats of Office documents is not supported. https://learn.microsoft.com/en-us/microsoft-365/compliance/ome-faq?view=o365-worldwide

This answer is outdated and all file types from User 1 are now supported (.doc, .docx, .xlsx) with a file size maximum of 512MB. User two answer of Mail 4 and Mail 6 are still correct.

Office 365 Message Encryption can encrypt messages of up to 25 megabytes. https://docs.microsoft.com/en-us/microsoft-365/compliance/legacy-information-for-message-encryption

User 1: mail 1 - exceeds max 25mb limit Mail 2 - .Doc is not supported Mail 3 - is supported and correct User 2: Mail 4 - is supported and correct Mail 5 - JPG not supported Mail 6 - Is supported. so the answer is User 1 Mail 3 only https://docs.microsoft.com/en-us/microsoft-365/compliance/ome-faq?view=o365-worldwide#:~:text=The%20maximum%20message%20size%20you,including%20attachments%2C%20is%2025%20MB. User 2 Mail 4 and Mail 6 only https://docs.microsoft.com/en-us/microsoft-365/compliance/ome?view=o365-worldwide#:~:text=Office%20365%20Message%20Encryption%20works%20with%20Outlook.com%2C%20Yahoo!%2C%20Gmail%2C%20and%20other%20email%20services.

This article says that .doc files will be protected https://support.microsoft.com/en-us/office/introduction-to-irm-for-email-messages-bb643d33-4a3f-4ac7-9770-fd50d95f58dc?ui=en-us&rs=en-us&ad=us#FileTypesforIRM

As per "https://docs.microsoft.com/en-us/microsoft-365/compliance/ome-faq?view=o365-worldwide" https://docs.microsoft.com/en-us/microsoft-365/compliance/ome-faq?view=o365-worldwide

User 1 can only send Mail 3, as OME does NOT support .doc files. See https://docs.microsoft.com/en-us/microsoft-365/compliance/ome-faq?view=o365-worldwide. It says "OME does not support the 97-2003 versions of the following Office programs: Word (.doc), Excel (.xls), and PowerPoint (.ppt)." User 2 answer looks correct to me.

On exam 1/20/2022

Take a look here https://docs.microsoft.com/en-us/microsoft-365/compliance/ome?view=o365-worldwide Outlook.com, Gmail, and Yahoo accounts receive a wrapper U1 -> 2,3 The maximum message size you can send with OME, including attachments, is 25 MB. Not to 1 U2 -> 4,6 Can't encrypt jpeg. Not to 5

User 1 - 2,3 seems right. Not Contoso domain and file extensions are supported. User 2 - I think 6 only. 4 is on Contoso domain. 5 is .jpg, which is not supported. 6 is .docx, supported and file size in small enough. Why are some people saying 5 is correct?

"With Office 365 Message Encryption, your organization can send and receive encrypted email messages between people inside and outside your organization."

https://docs.microsoft.com/en-us/microsoft-365/compliance/ome-faq?view=o365-worldwide#what-file-types-are-supported-as-attachments-in-protected-emails--do-attachments-inherit-the-protection-policies-associated-with-protected-emails- What file types are supported as attachments in protected emails? Do attachments inherit the protection policies associated with protected emails? You can attach any file type to a protected mail. With one exception, protection policies are applied only on the file formats mentioned in File types supported by the Azure Information Protection client. OME does not support the 97-2003 versions of the following Office programs: Word (.doc), Excel (.xls), and PowerPoint (.ppt). If a file format is supported, such as a Word, Excel, or PowerPoint file, the file is always protected, even after the attachment has been downloaded by the recipient. For example, say an attachment is protected by Do Not Forward. The original recipient downloads the file, creates a message to a new recipient and attaches the file. When the new recipient receives the file, the recipient will not be able to open the protected file.

Hi fellas! I am a bit confused with this one. I have created an OME rule and sent two (un)supported attachments. One DOC and one JPG. It appears that OME encrypts the whole message, not the individual attachments. So, shouldn't the answer be "Mail1, Mail2 and Mail3"? At least for User2, because I did not try sending 40MB large attachment. Am I missing something here?
