Exchange web services API - Get all mailboxes - exchange-server

Is there a way to get all the existing mailboxes in exchange? I need this to be able to get all the tasks from all mailboxes.
Thanks.

Not in the web service API itself. You would need to look at the Get-Mailbox cmdlet in Powershell.

Are there any alternatives Exchange EWS api?

Im currently using the Exchange EWS api to sync two calendars. There is a customer that does not want open up EWS to the public.
Are there any other methods, apis, etc to CRUD Exchange calendars?
DavMail is a POP/IMAP/SMTP/Caldav/Carddav/LDAP exchange gateway. It's implemented in Java and should run on any platform.
It's been a while since I've implemented it on local machines for single app use inside a WAN and also on web facing servers as a general gateway into Exchange for Linux users.
I don't know if it plays well with O365 etc, as I haven't needed to find out yet.
Its a SourceForge project with some sponsorship from the French Defense Agency.

Authentication/Authorization For Self-Hosted Exchange Servers

This page states that before an application can access the API (I'm particularly interested in the Calendar API), it must be registered with Azure AD. Is this also true for organizations that may host their own Exchange servers?
Could someone provide a breakdown of what's necessary for me to get started with accessing the API to access the users' Calendar? I'm aware of the API reference, but I'm not entirely sure what's necessary to do before I can use the API.
That page is for Office365, not self hosted ones.
You can access your local/self hosted Exchange server with Exchange Web Services by using username/password, or even your local AD if you set it up correctly.
The API it is talking about is not available to on-premise Exchange Server, it is only available to Exchange Online in Office 365. This may change in the future, but currently you cannot use it in on-premise. Exchange Web Services is the way to go for on-premise.

Configuring CRM with an Exchange Server outside O365 using SSS

I have a requirement where I need to configure my CRM Online with an Exchange Server which is hosted out of my organization's Office 365 to sync Emails for Incoming and Outgoing profiles.
Of the steps, I understand that I need to setup and Email Server Profile of type Exchange that has Server Location pointing to the Exchange Server which I have been using currently. However, I get an error saying that the configuration is invalid and I don't get to save the Incoming and Outgoing server locations. Also, do I need authentication for the same? If yes, of whom should it be? The current Incoming and Outgoing is set to the URL. (Without '/EWS/Exchange.asmx' which is used by default for hosting it on O365.
Any help / links to blogs that effectively explain this would really help.
Thanks !
Supported email service configurations for server-side synchronization
CRM Online only supports Server Side Synchronization with:
Exchange Online in the same tenant in Office365 (mail, tasks, etc.)
Gmail or Yahoo! Mail via POP3/SMTP (mail only)
Anything else is not (yet1) supported.
1 Online to On-Premise SSS is supposed to become supported at some point in the future
There are three ways of handling email processing in CRM:
Server-side synchronization
CRM for Outlook
Email Router
Server-side synchronization does not support hybrid deployments (e.g. CRM Online with Exchange On-premise), as Alex mentions.
I suggest looking into the Email Router. You install it on a machine which is then responsible for synchronizing email messages between CRM and Exchange. For an in-depth explanaion, see Email Router Demystified.
If you also need to synchronize Outlook contacts, tasks and appointments have a look at CRM for Outlook.

Reading Exchange Policies

Is there an API to read programmatically settings/policies from a given exchange server? Like this one.
It doesn't seem like there's an API via EWS.
The only API for this are the Powershell cmdlets.

How do I discover all mailboxes for an Exchange Server using Exchange Web Services?

I'm using Exchange Web Services Managed API 1.0 to access the Exchange servers (2007) in my organization. I need to iterate over all the mailboxes on a given server. I haven't seen a way to get the list of mailboxes defined for a given Exchange server. I have been able to use the AutoDiscover service to find the address of a hub server for a specific mailbox, but I'm interested in getting a list of all mailboxes. Can someone point me in the right direction?
If your problem is not yet solved I would you recommend use just pure LDAP queries instead of Exchange Web Services. The information which you need are saved in homeMDB, msExchHomeServerName and probably homeMTA Active Directory attributes. You can modify LDAP query from http://www.msexchange.org/tutorials/Creating_a_list_of_Users_and_their_email_addresses_in_Exchange_2000_2.html or http://technet.microsoft.com/en-us/library/bb125087(EXCHG.65).aspx to receive information which you need.
