attached mail as ItemAttachment about exchangelib HOT 10 CLOSED

I think the best option to find out what the difference between sending an item attachment from exchange and from Outlook is to create two identical emails , one from each system, and then use exchangelib to inspect all attriburtes on the two items to find out what the difference is.

from exchangelib.

First of all.
Thank you very much for your help :)

For the attributes I am not sure what code line to use.
print([f.name for f in Message.FIELDS if f.is_searchable])
I tried this one with

for f in nachricht.FIELDS:
   fw.write(f'{f.name} = {str(f)}')

with "fw" as a filewrite for a .txt document
The content is big and I do not know if it helps.
If you have a better approach for the needed information let me know.
attribute_0.txt
attribute_1.txt

from exchangelib.

I was thinking of something along these lines:

from exchangelib.items import Message

item_from_exchangelib = account.inbox.get(subject="Hello from exchangelib")
item_from_outlook = account.inbox.get(subject="Hello from outlook")

for f in Message.FIELDS:
    exchangelib_val = getattr(item_from_exchangelib, f.name)
    outlook_val = getattr(item_from_outlook, f.name)
    if exchangelib_val != outlook_val:
        print(f"Diff on field {f.name}. exchangelib: {exchangelib_val!r} Outlook: {outlook_val!r}")

from exchangelib.

analyse.txt

I got this textfile with the print content.
To the previous tests I reduced the mail to just the attached mail, your suggested subject, "test" as the body and the attached mail itself is very "plain" in its structure.

Hopefully this helps with finding a solution.

The text file only reports mime_content as being different, and that field is auto-generated. That doesn't get us any further, unfortunately.

from exchangelib.

Sorry my mistake. I did not format it in any way.
A little usage of notepad++ later and I got hopefully the same content just being displayed in a better way.

Now the document follows
Diff on field field.name
exchangelib: exchangelib value
Outlook: outlook value

analyse.txt

some values are ... very long.

from exchangelib.

The main difference I see is in the attachment:

exchangelib: [ItemAttachment(attachment_id=AttachmentId(id='AAMkADAzOWRmZmE2LWQ0OGYtNGNkOS1hYmMyLWU4MDU4ZGQxNjE0YwBGAAAAAAAqnHhcvxtCR7EVdJ/LFX5nBwC7iw9ZYLsmS4aOWEeRaxxvAAAAAAEMAAC7iw9ZYLsmS4aOWEeRaxxvAAACxrxWAAABEgAQADuaG27ZFkREkFoN0X7Hze8=', root_id=None, root_changekey=None), name='Test', content_type='application/octet-stream', content_id=None, content_location=None, size=4242, last_modified_time=EWSDateTime(2024, 2, 27, 14, 45, 44, tzinfo=EWSTimeZone(key='Europe/Berlin')), is_inline=False)] 
 Outlook: [ItemAttachment(attachment_id=AttachmentId(id='AAMkADAzOWRmZmE2LWQ0OGYtNGNkOS1hYmMyLWU4MDU4ZGQxNjE0YwBGAAAAAAAqnHhcvxtCR7EVdJ/LFX5nBwC7iw9ZYLsmS4aOWEeRaxxvAAAAAAEMAAC7iw9ZYLsmS4aOWEeRaxxvAAACxrxXAAABEgAQADz+vaxnVItFpGTwDeWWFpI=', root_id=None, root_changekey=None), name='Test', content_type=None, content_id=None, content_location=None, size=20814, last_modified_time=EWSDateTime(2024, 2, 27, 14, 46, 28, tzinfo=EWSTimeZone(key='Europe/Berlin')), is_inline=False)]

Main thing here is the difference in size and content_type. I don't know what causes that. Are you attaching the same message in both emails?

from exchangelib.

Yes I do attach the same message.

The attached mail has the subject = "Test", body = "Test" and no attachments itself. Very plain and simple.

What can I further do to help solving this issue?

from exchangelib.

I don't have any obvious ideas.

I don't really consider this a bug, since it's not a goal of exchangelib to have feature parity with Outlook, but please do post your solution here if you find one.

from exchangelib.

Closing, but it would still be great if you post any solution here so others can benefit :-)
