Using Classic Outlook on Windows for personal email, calendar, and contact management
Andrew,
I checked with our Escalation Engineers, and they say that the IDNA trace should not lock the OST. It could be our steps that need updating. One of the Escalation Engineers said he would help work through the trace with you. If you know a time you could work on this please let me know. Or, please respond in the In App ticket and we will coordinate it with you. Thanks for taking time to help us with this.
