Difference between Attaching a file & Uploading a file to the SharePoint site

Question

I facing a weird issue. I am able to upload a 32 mb file to a Document Library. But I am unable to attach same file to a task. Do I need to change settings other than Central Admin?

I have set limit to 50MB in Central Admin.

Answer 1

It's not weird, it's by design. Attachments limit size is (if I remember correctly) also limited by the <httpRuntime maxRequestLength="size"/> element in web.config. Check that.

Answer 2

Just a side note. <httpRuntime maxRequestLength="" /> does not work for IIS 7. It has a new setting under system.webServer. See this blog for a reference: http://weblogs.asp.net/jeffwids/archive/2009/09/24/from-iis6-maxrequestlength-to-iis7-maxallowedcontentlengthfile-specifying-maximum-file-upload-size.aspx

Answer 3

Also make sure that attachments are enabled on the Tasks list.
