I don't understand how syncing from xero to outlook is beneficial, when the real benefit is syncing outlook contacts to xero to save duplication of input. paying the extra subscription for something that doesn't really save you time? Should be two way syncing, such a simple concept

Apart from having to upgrade to the next Xero tier just to use this App, it doesn't synchronise phone numbers! Beggars belief......

After many years and still not fixed..

It seems to only sync name and email, but not address or phone number. Why?

Yup, does not sync the phone numbers - fatal flaw and now rendering it useless. I put in a ticket with Xero just to make sure they know so if it's still not working when you read this two months from now then what does that tell ya? :)

Sync works as promised, one way into a folder in Outlook. However, phone numbers are missing.
