Issue: Unable to Process Multiple Emails Simultaneously When Downloading Attachments and Uploading to SharePoint

从 MailLocal.java:680 的附件处理调用以及 SharePointConnection.java:268-297 中记录的上传流程开始。使用 Java Graph API 重现 Outlook 附件下载和 SharePoint 上传，然后验证一个连接能够处理来自多封电子邮件的附件并成功上传这些附件。

Describe the bug

When trying to download attachments from Outlook while simultaneously uploading files to SharePoint, it is not allowing multiple emails; it only processes one email at a time.

Note: Downloading attachments from a single email to local storage and uploading them to SharePoint is working fine using java graphapi.

Expected behavior

We need a process where, within a single connection, we can download attachments and upload them to SharePoint or directly download attachments to SharePoint using Java Graph API with a client secret and application ID.

How to reproduce

To download file from Outlook.
File file1 = new File(localFolder + "/" + sFileName);
System.out.printin("Path::"+LocalFolder +"/" + sFileName);
File folderTouploaded - new File(tempDownload);
for (File fileTemp : folderTouploaded.listriles()) [
if (fileTemp.isFile()) t
fileTemp.setwritable(true);
Logger-info("Name is :::" + fileTemp.getName());
Logger-info("Path is :::"+ fileTemp.getAbsolutePath());
sharerointconnection.upLoadFiLeToSharepoint(graphclient,sharePointsiterd(),sharePointdriveId(), tempDownload,
uploadPath, fileremp.getName(),file1);
deleterile(tempDownload +"/" +fileTemp.getName().tostring());

//To upload file-
Path srcFilePath = Paths.get(srcFolderName + "I" + fileName);
Logger.info("Checking::"+srcFolderName + "I" + fileName);
byte[] srcFileBytes = Files.readAtlBytes(srcfilePath);

DriveItem uploadedItem = drivertemRequestBuilden.content().buildRequest().put(srcFileBytes);
