Situation: Local User with SonicWall administrator permission cannot log in the firewall locally. Only default admin can login.

Troubleshooting: You need enable HTTPS for User login. Go to Network>Interface. Edit the local Interface, for example, 192.168.78.254.

Situation: The client has setup SonicWall Global VPN Client. When they try to establish the VPN, it shows connecting forever.

Troubleshooting: The VPN may not be enabled. Go to VPN>Settings, check enable.

Situation: in the past weeks, the client (A) can’t receive one of their customers (B) emails. No one in A company can’t receive the emails from company B.

Troubleshooting 1: For the sender

It may be that AOL/Yahoo etc are blocking emails from domains which do not have SPF set up. They are not blocking them in the usual way but are effectively dropping the connection at the network level when they check for SPF.

If you setup spf for your domain it should resolve the problem and allow your emails to flow.

This is the example how we fix the problem – Update the TXT records.

DMARC Record

Hostname:

_dmarc

Record:

v=DMARC1; p=none; pct=100; adkim=r; aspf=r

I’m doing this now and will reply back once confirmed.

UPDATE: I can confirm that after adding SPF records the emails are now going through. This is not very good in my opinion that AOL / Yahoo are just silently dropping the connection but I’m guessing that them get so much spam from domains without SPF that it is a large enough benefit to them to do it in this way.

Troubleshooting 2: Please ask the admin of the recipients’ to add your domain in their safe sender list and allow list in the spam filter.

Situation: The client has shared a folder in SharePoint 365 with a guest having edit permissions. When the Guest Contributor opens the link, he is able to upload files and create sub-folders. But he cannot delete or rename any files or folders.

Troubleshooting: “Share People you specify can edit” and “Anyone with the link can edit” are different. If you chose “Anyone with the link can edit”, the external user can upload files/folders, but can’t delete or rename them.

Situation: The external users can’t access shared SharePoint with this error: “External sharing is disabled”.

Resolution 1: Make sure external sharing at organization level is enabled. Please refer to these posts.

Situation; After the user update her OneNote, she can’t find the OneNote file.

Troubleshooting:

There are some steps to avoid situation with not being able to find OneNote files:

1. Check OneNote cache: Sometimes, OneNote stores changes to the notebook only in the cache. If OneNote is uninstalled or an older version of the notebook is opened in OneNote for Windows 10, the cache may be lost. To recover data from the cache, you can follow the instructions provided by Microsoft. Recovering Data from the OneNote Cache – Microsoft Support
2. Ensure Proper Syncing: Make sure your notes are properly synced with your OneDrive account. If you’re having issues with syncing, you might need to extend your OneDrive storage or delete some files in your Personal OneDrive.
3. Kindly check your account has been successfully logged in the OneNote App.
4. Backup Your Notes: Regularly back up your notes to prevent data loss. If you’re using an older version of OneNote on your device and can still find your notes, back them up first to prevent note loss.

5. Update OneNote Regularly: Keep your OneNote application updated to the latest version to avoid any compatibility or syncing issues.
