Thanks for posting about the new occurrence of this issue. A bug/incident has been escalated and the issue is actively being worked on. If I get any ETA about fix status I will post back.

This issue is reoccurring again for some users within our organization. We have OWA disabled for our users. We are using latest version of outlook client. The issue arises at the start of opening outlook and moving the cursor over the left side pane with calendar and email icon. The link redirects to https://outlook.office.com/opx/(workemailaddress)/activityfeed/?hostApp=outlookdesktop&culture=en-US. We have tried all the possible work arounds like changing register key, enabling disabling owa etc. But nothing seems to be working.

Yeah we are encountering the same issue over many different laptops and accounts, i've raised this to support in hopes of having them look over the issue and hopefully patch it.

I can report my end user is no longer having the issue. She stated it is not happening today.
