[evolution-patches] Exchange connector - patch for #72170

[Sushma Rai <rsushma novell com>]

Hi,

Attached is the patch for GAL offline related problems.
This also fixes a problem, where GAL addressbook was marked 
as editable when switched from offline to online mode.

Please review.

Thanks,
Sushma.
