Hello everyone,

Some of you may remember my previous thread about the same-ish issue (https://techcommunity.microsoft.com/t5/project/excel-reporting-can-t-connect-to-calendars-with-odata-anymore/m-p/4132119) that ended up being solved by a Project Online patch.

But somehow, the issue returned. Not the same cause, since it has nothing to do with authentication this time, but the same symptoms : trying to fetch Calendar Exceptions data from an Excel OData query doesn’t work anymore.

When trying to get the data, I am getting “Error 400 : Cannot get a CSOM-compatible PJContext for an HTTP request that started outside of CSOM.”

It seems the issue started this morning on my client’s tenant.

Has anyone else experienced the same issue ?
