Microsoft has resolved an issue in Outlook for Microsoft 365 that caused problems sending emails for users with too many nested folders. The problem may result in a Non-Delivery Report error. A fix will be rolled out to release channels later in October and December. Temporary workarounds are also available until the software is fixed.
Based on the meeting notes, here are the key takeaways:
– Microsoft has fixed an issue in Outlook for Microsoft 365 users which caused problems sending emails for those with too many nested folders.
– The issue is related to users with a large number of folders in their primary mailbox, and has resulted in users receiving Non-Delivery Reports (NDR) with the 0x80040305 error code.
– The Outlook Team has developed a fix for the problem, which will be rolled out to various release channels later this month or in December.
– Meanwhile, affected users are provided with temporary workarounds, including reducing the number of folders with subfolders to below 500 and keeping all mailbox folders collapsed rather than expanded.
– Microsoft also addressed other bugs in Microsoft 365 apps, such as crashing while typing or spell-checking a text and known issues triggering Gmail sign-in issues for classic Outlook users and causing Outlook to crash after opening.
