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.

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.

Excellent! Thanks! – neo269 Aug 5 '11 at 11:47

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:

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