Thanks @ConceptsWebActually it syncs two ways:
Daily at midnight.
And
Whenever there is a change in O365, 3CX will receive a real-time notification and the contact will appear in the Webclient pretty quickly.
Initial sync is also on the spot usually.
Yes.Thanks @ConceptsWeb
So each time for instance someones adds or edits a contact in his M365 account, the contact will be added/updated ?
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
