Zoom Calendar and Contacts Integration with Office 365 Will No Longer Support Basic Authentication Starting October 3, 2022
On Monday, October 3 2022, Stevens will begin requiring that all Zoom account integrations with Office 365 calendars use the more secure OAuth 2.0 standard. This change is being made in anticipation of Microsoft’s upcoming deprecation of Basic Authentication (“Basic Auth”) on all Office 365 accounts. Basic Auth was a simpler method of connecting to email and was significantly more vulnerable to malicious attacks. Microsoft is phasing out Basic Auth on October 1, 2022, to significantly improve the security of all email systems and accounts.
Functionalities and Tools Affected
Please note that this change specifically affects the Calendar and Contacts Integration in your Stevens Zoom profile. This integration, when enabled, allows a user’s Zoom desktop client to display meetings and contacts from their Outlook calendar.
The upcoming change will not affect the Microsoft add-in for Zoom, which users may have installed in Outlook to allow them to easily add Zoom meetings while scheduling Outlook calendar events.
What Users Can Expect
- Users who have not enabled Calendar and Contact Information in their Zoom profile will not be affected by this change.
- Most users who have enabled Calendar and Contact Information should already be using the modern OAuth 2.0 method, which has been the default option for some time. These users can expect no effects when the change takes place on October 3, 2022.
- Long-time Stevens Zoom users whose Zoom accounts predate OAuth 2.0, or users who deliberately opted not to use OAuth 2.0 when they enabled a Calendar and Contact Integration, will need to reauthorize all integrations to be sure they are using OAuth 2.0. To do this, follow the instructions below.
What To Do When You Receive a "Your Calendar Service Has Been Disconnected" Error in Zoom Desktop Client
After the change takes place on October 3, failure to re-configure an integration still using Basic Auth will result an error in the Zoom desktop app when the integration cannot connect with Microsoft Exchange to get calendar information. Below is an example of a typical expected error (with personal information redacted for privacy), reading Your calendar service has been disconnected from your account.
If you receive this error,
Step 1: Select the Configure Your Settings link
Step 2: This will take you to your Zoom profile to properly configure the integration
Step 3: Click Profile in the left-side menu
Step 4: Scroll down to the Others section
Step 5: Check under the heading Calendar and Contacts Integration
Step 6: Select Office 365
Step 7: Select Next
Step 8: Check Authorize with OAuth 2.0
Step 9: Select Authorize
Step 10: Sign in with your Stevens credentials
Step 11: If prompted, accept permissions requested by Zoom to access your calendar after authenticating
Step 12: Select Accept to proceed
Step 13: After authentication is complete, you will be returned to your Zoom profile
