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

從 MailLocal.java:680 的附件處理呼叫以及 SharePointConnection.java:268-297 中記錄的上傳流程開始。使用 Java Graph API 重現 Outlook 附件下載和 SharePoint 上傳，然後驗證一個連線能夠處理來自多封電子郵件的附件並成功上傳這些附件。

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);
