In October 2026, Exchange Web Services goes away β and with it the Public Folders workflow many teams used for shared contacts. Here's what to do about it.
Microsoft is switching Exchange Online fully to the Graph API. Public Folder contacts, EWS-based sync tools and legacy shared mailbox address books stop working when EWS access is turned off.
Any organization that keeps a shared contact list in Public Folders, uses an EWS-based contact sync tool, or relies on Outlook add-ins that read contacts over EWS.
Export your Public Folder contacts, import them into a normal mailbox or directly into Rolyio, and share them as labels. Your team sees the same contacts in Outlook β now synced through the Graph API, which is here to stay.
Rolyio is built on the Graph API from day one, adds roles and an audit trail on top, and even lets you share the same list with people on Google Workspace.
Set up your shared contacts on modern APIs in an afternoon, not a quarter.
