问题 Office 365 does not return the X-BackendOverrideCookie in response headers. I set the X-AnchorMailbox and X-PreferServerAffinity in the request headers properly. This does not trigger X-BackendOverrideCookie to be returned, as it says in MSDN. Why is this happening? Meanwhile, I tried the same thing with an on-premise Exchange 2016. Here I don't even set the X-AnchorMailbox and X-PreferServerAffinity and I get back the X-BackendOverrideCookie in each response. This is not good either, since I

问题 I am trying to create emails for my users using EWS Managed API 1.1, and need to use email templates our designers have created. I was able to successfully attach image ( say header.png ) and add an image tag like this ( using cid: before the image name ) in the html body. <img width=683 height=27 src="cid:header.png" alt="Header"> This works when I use msg.SendAndSaveCopy() method. It renders perfectly fine in both Sent Mail folder and the recipients inbox. However it is not working when I

问题 I'm trying to find a way to get the list of people that I'm a delegate for using the EWS API.

问题 I am writing an application(C#) to sync contacts,appointments,tasks etc from one mailbox to other. I am able to retrieve changes to these items using SyncFolderItems but could not find a way to copy the changes to a different mailbox. It looks like I have to create a new item for each of these types on the destination mailbox. If that is the case how do I get all the properties on the source item onto the new item on the destination. I am currently using exchange 2007 sp1 environment and want

问题 I try to send mails from out company exchange server via Python. My problem is, that I get a SSL error. I read a lot of pem-, cer-, crt-files, but I can not connect all these information to have success. I am sure, that if one can fix the issue in my little example script, one could fix the exchange script, too. I read a lot about certificates and ca_bundles, but I don't know how to apply all of that to my issue. Example-Script : import requests requests.get('https://mail.ourserver.loc')

问题 This is my scenario: I have to read email from exchange 2010 sp2 accounts. I have to use Exchange Web Services, POP3 and IMAP are blocked. I have to test my app in an environment where people can access their accounts through a web browser only in the intranet. I can't debug my app directly to this intranet.
