Briefly describe its main functions:

Email sending and receiving:

Break;

Contact:

Contact Group: Synchronize all data of owa and provide some simple business logic such as adding, deleting, and querying. For example, mobile, copy, and so on.

Break;

Large attachment upload: First, let's talk about the implementation goal. In the case of multiple users and high concurrency, the pressure on the server is minimized. Simply put, the upload is performed using the input control, use iis to host the uploaded content, read part of the content from the memory, write it into the hard disk, and then iterate until all the files are uploaded. Then, according to the test, the pressure on the server's memory for uploading 100 MB of files to 600 million users simultaneously cannot exceed 100 MB; compatible

Net 2.0-4.5;

Break;

Email signature:

Code attached:

Folder Root = Folder. Bind (MyExchangeService, WellKnownFolderName. Root );
UserConfiguration OWAConfig = UserConfiguration. Bind (MyExchangeService, "OWA. UserOptions ",
Root. ParentFolderId, UserConfigurationProperties. All );

String hsHtmlSigniture = "www.blah.com \"> Glen Scales ";
String stTextSig = "Text sig ";

If (OWAConfig. Dictionary. ContainsKey ("signaturehtml "))
{
OWAConfig. Dictionary ["signaturehtml"] = hsHtmlSigniture;
}
Else
{
OWAConfig. Dictionary. Add ("signaturehtml", hsHtmlSigniture );
}
If (OWAConfig. Dictionary. ContainsKey ("signaturetext "))
{
OWAConfig. Dictionary ["signaturetext"] = stTextSig;
}
Else
{
OWAConfig. Dictionary. Add ("signaturetext", stTextSig );
