**Please review and follow all directions in this article. This will reduce wait times and unnecessary troubleshooting.**

Overview

---

This article provides guidance and troubleshooting information for applications and services affected by the transition from @matsugov.us to @matsu.gov.

Expected Behavior

The transition from @matsugov.us to @matsu.gov will occur automatically for most systems on August 6th 2026.

You may be prompted to sign back in to Microsoft applications, including Outlook, Teams, OneDrive, and Office apps. Other non-Microsoft applications that use Microsoft 365 for authentication, such as Time & Attendance, ESRI, Cartegraph, New World ERP (LOGOS), EP&L, Adobe, ClearGov, Barracuda, KnowBe4, and TeamDynamix will also now use your matsu.gov login.

Emails sent to your old @matsugov.us address will continue to be delivered. Your @matsugov.us address will remain as an alias, but all new emails and replies will be sent from your @matsu.gov address.

Most issues can be resolved by signing out and back in with your new @matsu.gov credentials.

Applications Not Managed by IT

For applications not managed by Borough IT, application administrators or software vendors may need to update usernames from @matsugov.us to @matsu.gov.

In some cases, the application may continue using your existing @matsugov.us username and no changes will be required. If an application still requires you to sign in using your .us username after the migration, continue using the existing username unless you are instructed otherwise by the application administrator or vendor.

The following applications are not managed by Borough IT. For account assistance, username updates, questions, or troubleshooting, please contact the appropriate department or application administrator.

Occasional syncing/sign in issues. Most sign-in and synchronization issues can be resolved by signing out and back in.

1. Open a Microsoft Office product (Word, Excel, OneNote).
2. Select File > Account > Sign Out
3. Click Sign In, on top right, and enter your new email address first.last@matsu.gov

Microsoft OneDrive

Syncing/sharing with OneDrive may be interrupted. If files aren't available, or syncing is misaligned, follow the steps below.

1. Click the Microsoft OneDrive on the bottom-right.
2. Select the gear icon on top right > Settings > Account > Unlink this PC
3. Click OneDrive and sign back in using first.last@matsu.gov
4. Select Use this Folder when prompted. OneDrive will verify the existing files and reconnect them to your account.

Shared files/folders within OneDrive will need to be reshared.

1. Navigate to applicable file/folder
2. Click the 3 dots and select "Manage Access"
3. Click "Links" and delete old links
4. Recreate new links with appropriate permissions and users

Microsoft Teams

You may be prompted to sign out and sign back in.

1. Close Microsoft Teams.
2. Open Teams again.
3. Sign in using your new first.last@matsu.gov email address.

If Teams displays synchronization or authentication errors, sign out completely and sign back in with your new account.

Microsoft Teams OneDrive App

Accessing the OneDrive app in Microsoft Teams may result in an error: 404 Files not found.
To resolve this:

1. Create a 1:1 chat with another user.
2. In the message box, select Actions and apps > Attach file > Upload from this device.
3. Select a file you sent to the other user, then select Open.
4. Press Enter to send the file or select Send.
5. After sending the file, navigate to the OneDrive app in Teams.

Note: If the OneDrive app still doesn't open after completing the above steps, you may need to restart your computer.

Mobile Devices

If Outlook, Teams, or other Microsoft apps on your mobile device stop synchronizing:

1. Open the affected application.
2. Sign out.
3. Sign back in using first.last@matsu.gov.

Most mobile applications will automatically prompt for re-authentication if needed.

Web Browsers

For websites that use your Borough email address as a username:

• Update any saved passwords or autofill entries that reference @matsugov.us.
• If a website automatically fills your old username, remove the saved credentials and sign in again.
• If the application continues to require the @matsugov.us username, continue using it unless instructed otherwise.

For Microsoft Edge:

You may be prompted to sign back in to Microsoft Edge using your new@matsu.gov account.

1. Open Microsoft Edge.
2. Select your profile icon in the upper-right corner.
3. If prompted, sign in using your new first.last@matsu.gov email address.
4. Verify that synchronization completes successfully.

1Password

**Important Note: Remember to update all login information for credentials stored within 1Password to reflect the correct user account first.last@matsu.gov**

Review any stored logins that use your Borough email address as the username.

• Update stored credentials to first.last@matsu.gov when the application has been updated to use the new email address.
• Some applications may continue using first.last@matsugov.us. Continue using the username that works unless instructed otherwise by the application owner.

Miscellaneous changes

• Update your email signature
  • Go to File > Settings > Account > Signature
• Update any company letterhead or documents that reference your email or shared email addresses
