Recently, I encountered an embarrassing problem when I was working on an exchange2013 email project. I have adjusted the attachment size to 200M. The modification method is not much to say here (uploading the attachment size through OWA is mainly by modifying the IIS configuration file). After the modification is completed, log in to OWA through IE browser and upload attachments exceeding 30M. The screenshot is as follows:

The following errors were found in IE:

Process:

For this problem, I use other browsers, such as Google, Microsoft Edge, etc. to upload attachments above 30 MB are normal. It is not possible to use IE browser. depressed

Helpless to Microsoft for help, after nearly a month of analysis process, Microsoft gave a reply:

After research by senior engineers, this issue is a known Issue for Exchange 2013 OWA on large attachment handling and IE compatibility

If you also encounter the same problem, know that this is a BUG on the line, Microsoft has not yet given a patch, because this BUG involves a relatively small surface, using other browsers can be solved in disguise, so Microsoft has no repair plan.
