-Both of our authentication methods can fail if the Enterprise Applications entry for the sync in Azure AD is deleted or if it has had its permissions modified. We go above and beyond the average software reseller because we built our business on trust. As active members in the IT community, we work to support our clients’ businesses and provide them with peace of mind. After these instructions, ensure the sync settings are correct and check everything is working well. For managed setups, we can push a PowerShell script with Intune or Group Policy to clear cached tokens on all devices. A quick look at the Microsoft Entra Connect Health portal helps us see if sync tasks are current and the connection to Microsoft 365 is steady.
+Our relationship to the Microsoft Partner Network allows us to provide competitive pricing and authentic software and support, all with a much-needed human element. On Windows, open Credential Manager, pick Windows Credentials, and remove anything related to Office 365 or Microsoft 365. For managed environments, we use Intune or Group Policy to force sign-in credential sync and clear old tokens.

 Troubleshooting Microsoft 365 sync issues

+This pops up a lot after admins reset a password in the Microsoft 365 admin center. That changes the password in Microsoft Entra ID, but not right away in your local Active Directory. You end up with mismatched passwords between the cloud and your local network. If you don't wish an inactive user to be made active by the M365 sync, you can add the user's email address to the sync forbid list. You can do this in the Microsoft 365 Sync Wizard on the configuration page of your platform settings. Knowing the reasons behind the Outlook sync issues will help us to fix this problem and prevent issues in communication and workflow.
-Similarly you should review the Users Deactivated sheet on the sync summary spreadsheet attachment as you can also delete these users to bring your total down. You'll also receive a mail (to the alternate email and to your admin email) from Microsoft 365 that indicates your tenant has encountered directory synchronization errors. For details see Identify directory synchronization errors in Microsoft 365. We also check the synchronization scheduler to confirm delta and full sync cycles finish successfully. We check that Microsoft Entra Connect (Azure AD Connect) runs the latest version and password sync is on.

 Common Reasons Behind Outlook Sync Issues
-If the old password still works, the reset probably hasn’t synced. To resolve these issues you should run the steps in this article and check [[https://lab.nltvc.com/jeromeb8725341|flush DNS and re-sync Outlook]] whether the groups in your sync's filtering preference contain users in Azure AD. The simplest way to resolve authentication issues is to rerun the authentication process by clicking the Sign in with Microsoft on the Microsoft 365 settings page.

-Now, we will verify the server settings to fix the Outlook synchronization error. Once you have completed the steps to fix Outlook sync errors, kindly check if the error has been fixed or not. The M365 sync establishes a synced dataset based on your M365 data and the filtering configuration of your sync.
+Our training has quick guides about  what happens after you update your password. For example, you might get signed out or have to reauthenticate on your phone. We also remind users to refresh their Office sign-in token by signing out of all Microsoft apps and signing back in with the new password.

-We also scan Event Viewer logs under Applications and Services [[https://classifieds.ocala-news.com/author/marquita76x|FixTechGuide email error solutions]] Logs → Directory Synchronization for Event IDs like 650–657 (for sync activity). Errors like Event ID 611 point to invalid replication data or outdated software. The error message in the Summary sheet of the Sync Summary spreadsheet attachment can also highlight the reason for this.

+Troubleshooting Co-Authoring and Collaboration Errors
-This blog talks about the causes behind Outlook synchronization errors and a few solutions to fix Outlook sync issues. We have shared five manual methods in this blog to resolve the Outlook syncing errors. Apart from this, we also discuss the Shoviv OST to PST Converter Tool, a professional way to repair, recover, and convert Outlook data files. This solution will be beneficial for users who are facing Outlook syncing issues because of corrupted PST or OST files. Users can also try its free demo version in their system and process the first 50 items from each folder freely.
+On the sync server, we open the Synchronization Service Manager and check that the last sync finished without errors. Azure AD Connect handles password sync, but it runs on a schedule—usually every 30 minutes. So, if you just changed your password, there might be a short window where your old password still works and the new one hasn’t reached every system.
 The sync will fail if it can't find any users that comply with your filtering preferences or the system's requirements for user records. The system requires that users have a first name, last name and a valid email address that conforms with your domain lock if enabled. Microsoft 365 is a robust platform, but when problems arise, fast resolution is key to productivity. From sync errors to sign-in challenges and collaboration setbacks, these common Office 365 troubleshooting techniques can restore service quickly. After performing these steps, Outlook’s all folders will be synced to the server.
+Methods to fix Microsoft Outlook syncing error
+Before finding solutions, we suggest that users check their internet connection. Sometimes, Outlook sync issues can arise because of poor internet connection. If you are still facing this issue, kindly follow the solutions below to fix the sync issues in Outlook.
-Users can also convert OST files into various file formats, including PST, HTML, EML, MSG, vCard, etc. It also provides the option to export the Outlook OST file into Office 365 and Live Exchange mailboxes. This software also has a splitter option to split large-sized PST files into smaller ones, helping users prevent oversized PST file issues. Incorrect Outlook settings can also be one of the reasons behind Outlook synchronization errors. We keep password synchronization reliable by staying proactive and making sure users know how their actions affect access across Microsoft 365 and their devices. If sync keeps failing, we make sure the Microsoft Entra Connect service account has the right permissions and the server connects to the domain controller.
+We check that the Work or School Account in Windows Settings is active and linked to the right domain. The sync will fail if the groups you selected to load users from no longer exist in Azure AD. Typically this is because the selected groups have been deleted from Azure [[https://demo.safecircle.family/read-blog/38191_saying-the-internet-is-disconnected-but-connected-microsoft-q-amp-a.html|mailbox not updating on IMAP]] AD since the M365 sync was configured on your account.
-With apps syncing across devices and cloud services, sync issues are among the most frequently reported M365 problems. These can include missing files, ghost icons, or documents that do not update in real-time. Here, we will [[https://customerscomm.com/read-blog/145983_repair-outlook-profile-for-office-365-and-exchange-account.html|Office 365 sync problems and login fixes]] discuss the five manual methods to fix sync issues in Outlook or OWA.
