问题 Has anyone else discovered a memory leak issue with Pull Subscriptions ( ExchangeService.SubscribeToPullNotifications() ) in Exchange Managed Web Services API? When calling PullSubscription.GetEvents() the memory utilization climbs 4K with nearly every polling call. The only way I've been able to keep the memory utilization down is by forcing garbage collection (via GC.Collect() ) after every call - an unnecessary path. I am surprised to see the API hasn't changed for almost a year. 回答1: This

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 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'm using Exchange Web Services Managed API 1.1 to connect to Exchange server 2010 and then find out new emails received. Now I want to save a copy of the .msg file to a folder on the disk. I do not want to use any paid third party to integrate. Any help will be appreciated. 回答1: If you are happy to save into the .eml format instead, it can be done very easily just using EWS and no third party libraries. The .eml file will contain all the same information and can be opened by Outlook in the

问题 I have the following scenario: I check a mailbox to which emails with some relevant information are sent to to get the information from it. I use a lot of search filters to find the specific email and to get the correct one: var collection = new SearchFilter.SearchFilterCollection(LogicalOperator.And); collection.Add(new SearchFilter.ContainsSubstring(ItemSchema.Body, "text1", ContainmentMode.Substring, ComparisonMode.Exact)); collection.Add(new SearchFilter.ContainsSubstring(ItemSchema.Body,

问题 all I need to do is to retrieve all contacts from Microsoft Exchange. I did some research and the best possible option for me should be to use EWS Managed API. I am using Visual Studio and C# programming leanguage. I think I am able to connect to Office365 account, because I am able to send a message in a program to specific email. But I am not able to retrieve the contacts. If I create a contact directly in source code, the contact will be created in Office365->People aplication. But I don't
