Title: Users can't access existing contacts or create new contacts in Outlook on the web
More info: When affected users click on contacts, no information is displayed. Additionally, when those users click on "New Contact", nothing happens. Whilst we isolate the source of impact, we recommend using Outlook Monarch or Microsoft Teams to avoid this issue. Additionally, admins for affected users may be able to mitigate the impact by configuring the conditional access policies for the "Microsoft People Cards Service" and "Office Online Loki SSO" apps using the guidelines provided in the articles below:

Scope of impact: Your organization is affected by this event, and users attempting to access existing contacts or create new contacts in Outlook on the web are impacted.
