When Microsoft 365 stops working as expected, start with the shortest official checks before you reinstall anything.
Problem Description: Log Issue Microsoft 365
I can't access my installed office apps as I can no longer sign in. I can't sign in to Edge either, however if I go to my Microsoft account in Edge it opens fine. I have had increasing problems since the 24H2 update and have also lost the search functionality in the desktop. When trying to sign in to Office apps I get the following error: Something went wrong [7q6ca] #### **Correlation Id:** 8de70a91-eb8b-4d0c-8225-4658c88a6f9e #### **Timestamp:** 2026-01-15T12:26:08.000Z #### **DPTI:** 3cf14a6df1939659db2e322713ffab3875f121843c39510791acbf0a0d7372c1 #### **Message:** An unexpected error occurred. #### **Tag:** 7q6ca #### **Code:** 1067 I have tried getting hold of Microsoft help but this also does not work, I guess for the same reason.
Quick Answer for Microsoft 365 Won't Complete Task
Clear stored credentials by opening Credential Manager (Win+S), going to Windows Credentials, and removing entries related to MicrosoftOffice or MicrosoftAccount, then restart your PC.
Likely Causes Behind Common Sign-in Triggers
The Microsoft account or license context may not match the purchase or device.
Cached credentials, outdated builds, or damaged local components can trigger sign-in & login problems.
A file-specific corruption or add-in conflict can mimic a broader application failure.
Recommended Solution: Fixing Sign-in Step by Step
When to use this: Apply these steps when the symptoms match and you can access the relevant Microsoft account or administrator.
If the issue persists, repair Office apps by navigating to Settings > Apps > Installed apps, finding Microsoft Office, clicking Modify, and choosing Repair to reinstall missing or corrupted components.
If still unresolved, delete temporary files and try again.
Alternative Solutions for Broader Sign-in Workarounds
Retry the Microsoft-side steps after restarting the app and device.
Test the same action in a private browser session or a new blank file to isolate account vs file issues.
Capture exact error text and screenshots before contacting Microsoft Support or your administrator.
Working with WPS Office: Using WPS While Microsoft 365 Is Unavailable

WPS Office cannot replace Microsoft account, activation, or cloud fixes for this scenario. It remains one of the best free Microsoft Office-compatible alternatives for opening and editing local files.
Download and install WPS Office from the official website.
Open local Word, Excel, PowerPoint, or PDF files in the matching WPS app.
Save a working copy locally while Microsoft-side issues are resolved.
Return to Microsoft Office after the primary fix succeeds.
If you need a practical local workspace in the meantime, try WPS Office.
Prevention Tips for Avoiding Repeat Sign-in
Keep one primary Microsoft account for subscriptions and Office sign-in.
Install updates for Office and Windows before retrying failed workflows.
Back up important files before repair, reset, or reinstall actions.
Register more than one MFA method and keep recovery contacts current.
FAQs About Log Troubleshooting FAQ
Can WPS Office fix this sign-in & login problems issue directly? Only when the WPS steps match the formatting or file task. Account, activation, and cloud issues stay on the Microsoft side.
Should I reinstall Microsoft 365 before trying these steps? Not first. Confirm account, license, and the exact error before reinstalling.
What should I send to Microsoft Support? The affected account email, device type, Office version, exact error text, and screenshots with personal data hidden.
