Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi all,
The Outlook Team has implemented a fix for this issue. The fix is now available in the Office Beta Channel with Version 2306 (Build 16519.20002). If you can test with Office Beta please do and let us know if you see any issues. To submit feedback on the fix in Beta Channel for Outlook Desktop click Help, Contact Support.
The fix should get to Current Channel in late June with Version 2306. I will update the Known Issue with further release status as I get it. I am updating the Known Issue article today with this same information above, Outlook prompts “Retrieving templates from server” after selecting the From field drop down - Microsoft Support.
