We are pleased to share that the OHDSI MS Teams environment and collaborator emails are being restored. Most collaborators should have access now, and the remaining accounts will be fully operational shortly.

We know this has been a challenging few weeks, and we sincerely apologize for the disruption. Our team has implemented new security measures to ensure the stability and resilience of our open-science infrastructure moving forward.

Hi all, yes, we are now having new technical dificulties with our OHDSI MSTeams environment and email accounts. We are hopeful our colleagues at Microsoft and BTPros can resolve the issue and identify root cause so that we dont experience this more. We will use the forums and ohdsi linkedin to provide updates as we learn more. Sorry all for the inconvenience and thank you for your patience.
