This module is an ORM for your Exchange mailbox, providing Django-style access to all your data. It is a platform-independent, well-performing, well-behaving, well-documented, well-tested and simple interface for communicating with an on-premise Microsoft Exchange 2007-2016 server or Office365 using Exchange Web Services (EWS). Among other things, it implements autodiscover, and functions for searching, creating, updating, deleting, exporting and uploading calendar, mailbox, task, contact and distribution list items.,There are multiple ways of navigating the folder tree and searching for folders. Globbing and absolute path may create unexpected results if your folder names contain slashes.,Finally, the bulk methods defined on the Account class have an optional chunk_size argument that you can use to set a non-default page size when fetching, creating, updating or deleting items.,A QuerySet can be indexed and sliced like a normal Python list. Slicing and indexing of the QuerySet is efficient because it only fetches the necessary items to perform the slicing. Slicing from the end is also efficient, but then you might as well reverse the sorting.

pip install exchangelib

pip install exchangelib[kerberos]
pip install exchangelib[sspi]

pip install exchangelib[complete]

pip install git + https: //github.com/ecederstrand/exchangelib.git

apt - get install libxml2 - dev libxslt1 - dev

# For Kerberos support, also install these:
   apt - get install libkrb5 - dev build - essential libssl - dev libffi - dev python - dev

# For Kerberos support, install these:
   yum install gcc python - devel krb5 - devel krb5 - workstation python - devel

This module provides an well-performing, well-behaving, platform-independent and simple interface for communicating with a Microsoft Exchange 2007-2016 Server or Office365 using Exchange Web Services (EWS). It currently implements autodiscover, and functions for searching, creating, updating, deleting, exporting and uploading calendar, mailbox, task, contact and distribution list items.,Exchange supports backup and restore of folder contents using special export and upload services. They are available on the Account model:,Finally, the bulk methods defined on the Account class have an optional chunk_size argument that you can use to set a non-default page size when fetching, creating, updating or deleting items.,Extended properties makes it possible to attach custom key-value pairs to items and folders on the Exchange server. There are multiple online resources that describe working with extended properties, and list many of the magic values that are used by existing Exchange clients to store common and custom properties. The following is not a comprehensive description of the possibilities, but we do intend to support all the possibilities provided by EWS.

Here's a short example of how exchangelib works. Let's print the first 100 inbox messages in reverse order:

from exchangelib
import Credentials, Account

credentials = Credentials('john@example.com', 'topsecret')
account = Account('john@example.com', credentials = credentials, autodiscover = True)

for item in account.inbox.all().order_by('-datetime_received')[: 100]:
   print(item.subject, item.sender, item.datetime_received)

You can install this package from PyPI:

pip install exchangelib

The default installation does not support Kerberos. For additional Kerberos support, install with the extra kerberos dependencies:

pip install exchangelib[kerberos]

On Ubuntu:

apt - get install libxml2 - dev libxslt1 - dev

# For Kerberos support, also install these:
   apt - get install libkrb5 - dev build - essential libssl - dev libffi - dev python - dev

On CentOS:

# For Kerberos support, install these:
   yum install gcc python - devel krb5 - devel krb5 - workstation python - devel

The mbox format is the classic format for storing mail on Unix systems. All messages in an mbox mailbox are stored in a single file with the beginning of each message indicated by a line whose first five characters are “From “.,A subclass of Mailbox for mailboxes in mbox format. Parameter factory is a callable object that accepts a file-like message representation (which behaves as if opened in binary mode) and returns a custom representation. If factory is None, mboxMessage is used as the default message representation. If create is True, the mailbox is created if it does not exist.,If create is True and the dirname path exists, it will be treated as an existing maildir without attempting to verify its directory layout.,A subclass of Mailbox for mailboxes in MH format. Parameter factory is a callable object that accepts a file-like message representation (which behaves as if opened in binary mode) and returns a custom representation. If factory is None, MHMessage is used as the default message representation. If create is True, the mailbox is created if it does not exist.

import mailbox
mailbox.Maildir.colon = '!'

import mailbox
for message in mailbox.mbox('~/mbox'):
   subject = message['subject'] # Could possibly be None.
if subject and 'python' in subject.lower():
   print(subject)

import mailbox
destination = mailbox.MH('~/Mail')
destination.lock()
for message in mailbox.Babyl('~/RMAIL'):
   destination.add(mailbox.MHMessage(message))
destination.flush()
destination.unlock()

import mailbox
import email.errors

list_names = ('python-list', 'python-dev', 'python-bugs')

boxes = {
   name: mailbox.mbox('~/email/%s' % name) for name in list_names
}
inbox = mailbox.Maildir('~/Maildir', factory = None)

for key in inbox.iterkeys():
   try:
   message = inbox[key]
except email.errors.MessageParseError:
   continue # The message is malformed.Just leave it.

for name in list_names:
   list_id = message['list-id']
if list_id and name in list_id:
   # Get mailbox to use
box = boxes[name]

# Write copy to disk before removing original.
# If there 's a crash, you might duplicate a message, but
# that 's better than losing a message completely.
box.lock()
box.add(message)
box.flush()
box.unlock()

# Remove original message
inbox.lock()
inbox.discard(key)
inbox.flush()
inbox.unlock()
break # Found destination, so stop looking.

for box in boxes.itervalues():
   box.close()

A really simple example from the exchangelib documentation follows, which will show the top 10 emails I mentioned:

from exchangelib
import Credentials, Account

credentials = Credentials('john@example.com', 'topsecret')
account = Account('john@example.com', credentials = credentials, autodiscover = True)

for item in account.inbox.all().order_by('-datetime_received')[: 10]:
   print(item.subject, item.sender, item.datetime_received)

A lot of functionality is already built into exchangelib, and thumbscr-ews builds on top of the example code provided above. A common flow using exchangelib would be to get an account, get a folder of interest, loop over objects in that folder and print interesting information. If you wanted to search through mail for example, you would filter() on the objects retrieved from that folder. Keep in mind that the search variable does use a specific format for more fancy searching.

mails = account.inbox.filter("Body:Password").order_by('-datetime_received')

Getting this working I had to do some fiddling with the exchangelib building blocks. While exchangelib provided a ResolveNames call, it was only used under the hood by other functions with the call method. I had to do some scratching around the code base to work out how its used:

# Login to the account
account = Account(username, credentials = credentials, autodiscover = True, access_type = DELEGATE)

# Get a list of aa - > zz
atoz = [''.join(x) for x in itertools.product(string.ascii_lowercase, repeat = 2)]
for entry in atoz:
   # Search
for sub strings(entry) and print out all returned.
for names in ResolveNames(account.protocol).call(unresolved_entries = (entry, )):
   click.secho(f '{names}')
