Accessing multiple shared calendars with one account

[hausekla]

Hi,

In version exchangelib==5.1.0 I used to access shared calendars with one account like this:

class ExchangeCalendars(object):

    def __init__(self):
        self.credentials = Credentials('username', 'password')
        self.config = Configuration(
            service_endpoint="https://mail.myserver.cz/EWS/Exchange.asmx",
            credentials=self.credentials,
            auth_type='NTLM'
        )
        self.account = Account(primary_smtp_address="username@myserver.cz", config=self.config, autodiscover=False, access_type=DELEGATE)
        
    
    def getCal(self, primary_smtp_address):
        return SingleFolderQuerySet(account=self.account,folder=DistinguishedFolderId(id=Calendar.DISTINGUISHED_FOLDER_ID, mailbox=Mailbox(email_address=primary_smtp_address))).resolve()

On returned folder I call sync_items, store sync state and so on, and i could do it on multiple email addresses (I use one connection).

After upgrading to version exchangelib==5.5.1, this stop working. I Chnge getCal function to:

SingleFolderQuerySet(account=self.account, folder=Folder(root=self.account.root, _distinguished_id=DistinguishedFolderId(id=Calendar.DISTINGUISHED_FOLDER_ID, mailbox=Mailbox(email_address=primary_smtp_address)))).resolve()

This returned folder without error, but sync_items returned no valuest.

I know, that I could create Account for every shared calendar, and it will work, but I thing, that every Account use his own connection, so server kick me off (to meny connections from one source), when I want to read lot of calendars.

An Account will share TCP connection with other accounts pointing tongue same server, so you can safely create new Account objects for your requests.
