If you look at objectid on annotation it contains the Guid Id for the parent activity and the logicalname of the activity type (e.g. "letter").
The objectid on activitymimeattachment also has the Id of the parent activity, which in this case is always an email, however the logicalname is always "activitymimeattachment" which is incorrect. It should be "email" or whatever the logical name of an email template is...

Thank you for your feedback. Since this does not block any scenarios, we are not planning to consider this at this point

I'm a bit lost on what you're saying is the problem. In the title you say "ObjectId on activitymimeattachment has incorrect logical name", meaning you think "objectid" is incorrect. In the description you say, "however the logicalname is always 'activitymimeattachment' which is incorrect", meaning you think "activitymimeattachment" is incorrect. Although this is the logical name of the entity, so I'm guessing that was a typo. In any case, your assertion, "the Id of the parent activity, which in this case is always an email", is incorrect. ActivityMimeAttachments can have any activity as a parent; Task, Appointment, etc. Because they can be attached to any activity, "objectid" is correct.

Whoops, I was mistaken. Activity Mime Attachment is infact only used for emails. After some further investingation, I agree there is a bug.
