Have been using Zoho mail - both the new Apple app & online version - for a few weeks now

Overall it's great and has good functionality - and thanks for the help with a few questions so far

As a new question - how do I get Zoho mail (both versions) to sync with ALL my Zoho CRM contacts?

- I have hit the sync contacts button - but it has only found 107 contacts (I have a few hundred in Zoho CRM)

- when composing an email, it suggests lookup CRM contacts - but only seems to find the 107 already synced

The sync only seems to apply to contacts I have already emailed from / to Zoho mail 

Would appreciate any light you can shed?

Thanks

Ross
