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

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);

MailLocal.java:680 の添付ファイル処理呼び出しと、SharePointConnection.java:268-297 に記録されているアップロードフローから始めます。Java Graph API を使用して Outlook の添付ファイルのダウンロードと SharePoint へのアップロードを再現し、その後、1つの接続で複数のメールの添付ファイルを処理し、正常にアップロードできることを確認します。
