Fortigate 5.0 , Allow only google sites and outlook

Hi, I have one problem, I succeeded To block all website and allow only google sites and some sites + outlook to sync to google Apps, but my problem is only when I try to sync with google apps mail (google calendar not sync and note and tasks in outlook ) it give me error that (check your connection )

I'm able to send emails and receive emails in outlook and that is good  , but I'm not able to sync google calendar and note and tasks ) this is only my problem and this is what I done here in web filter ( I hope to find good solution  from you ) 

config

show webfilter profile 'INTERNET LIMITED ACCESS USERS' config webfilter profile     edit "INTERNET LIMITED ACCESS USERS"         set ovrd-perm bannedword-override urlfilter-override fortiguard-wf-override contenttype-check-override             config override                 set ovrd-user-group ""             end             config web                 set urlfilter-table 1             end             config ftgd-wf                 unset options                     config filters                         edit 1                             set category 140                         next                         edit 2                             set category 141                         next                         edit 3                             set action block                             set category 24                         next                         edit 4                             set action block                             set category 19                         next                         edit 5                             set action block                             set category 75                         next                         edit 6                             set action block                             set category 76                         next                         edit 7                             set action block                             set category 72                         next                         edit 8                             set action block                             set category 25                         next                     end             end     next end
