I upgraded to Mojave (10.14.2) the other day and, apart from some initial coniptions with 1Password, all is going well except Word and Excel (16.16.3 standalone version) crash on opening. The only bit in the crash report that's in understandable everyday English says:

Termination Reason: DYLD, 0x1 Library missing. Dyld: launch, loading dependent libraries. The most important one is Outlook and I get the following message. On November 6, 2019, the new Outlook for Mac was announced at Microsoft Ignite. The new Outlook is now available to users in Insider Fast. Fix for missing group headers when the message.

Termination Reason: DYLD, [0x1] Library missing
This seems clear enough (although the reference to “CORPSE” is a bit of a worry for someone in his 70th year) but I’m very unsure about what to do about it. Google search results tell me that many others are unsure too, including the Microsoft forum which advised a user to delete the “com.microsoft.word” folder (doesn’t exist on my system) or reinstall Office. Apparently the reinstall worked for the user but I’m reluctant to do this because I can’t locate my original Office install disc and its serial number which I’m pretty sure will be required.
The Office apps will launch fine when the system is booted from a High Sierra clone. This strongly suggests that Mojave is the culprit and I held off upgrading until now for this very reason - ie allow compatibility etc issues to be sorted out. Minor rant: In view of Mojave’s extensive lead time it’s bizarre that software from one of the world’s biggest companies and used by so many is suddenly missing an essential library (on my system anyway). It’s enough to make me resort to Pages and Numbers…
…hmm now there’s an idea, these look perfectly capable for my limited requirements but, before I do that, does anyone have any troubleshooting suggestions for my inoperative Office installation?

The improved Microsoft 365 Defender portal is now available. This new experience brings Defender for Endpoint, Defender for Office 365, Microsoft 365 Defender, and more into the Microsoft 365 security center. Learn what's new.

Note

If you're an admin in an organization with Exchange Online mailboxes, we recommend that you use the Submissions page in the Microsoft 365 Defender portal. For more information, see Use Admin Submission to submit suspected spam, phish, URLs, and files to Microsoft.

It can be frustrating when users in your organization receive junk messages (spam) or phishing messages in their Inbox, or if they don't receive a legitimate email message because it's marked as junk. We're constantly fine-tuning our spam filters to be more accurate.

You and your users can help this process by submitting false positives (good email marked as bad), false negatives (bad mail allowed) and phishing messages to Microsoft for analysis.

Note

Because of the high volume of submissions that we receive, we may not be able to answer all requests for analysis.

Submit false negatives to Microsoft

Tip

Instead of using the following procedures to report false negatives, users in Outlook and Outlook on the web (formerly known as Outlook Web App) can use the Report Message add-in or the Report Phishing add-in. For information about how to install and use these tools, see Enable the Report Message add-in and Enable the Report Phishing add-in.

If you receive a message that passed through spam filtering that should have been identified as spam or phishing, you can submit the message to the Microsoft Spam Analysis and Microsoft Phishing Analysis teams as appropriate. The analysts will review the message and add it to the service-wide filters if it meets the classification criteria.

Create a new, blank email message with the one of the following recipients:
- Junk: junk@office365.microsoft.com
- Phishing: phish@office365.microsoft.com
Drag and drop the junk or phishing message into the new message. This will save the junk or phishing message as an attachment in the new message. Don't copy and paste the content of the message or forward the message (we need the original message so we can inspect the message headers).
Note
- You can attach multiple messages in the new message. Make sure that all the messages are the same type: either phishing messages or junk email messages.
- Leave the body of the new message empty.
- Use either .msg (default Outlook format) or .eml (default Outlook on the Web format) formats for the attached messages.
When you're finished, click Send.

Tip

Admins have several different ways to block specific messages that are being misidentified as spam. For details, see Create blocked sender lists in EOP.

If a message was incorrectly identified as spam, you can submit the message to the Microsoft Spam Analysis Team. The analysts will evaluate the message, and (depending on the results of the analysis) the service-wide filters can be adjusted to allow the message through.
