When you’re trying to send an email from a shared mailbox and Outlook says your email address is not valid, you need to fix the issue. In this blog post, we’ll show you how to fix shared mailbox not updating in Outlook so that you can get back to work.

Quick Steps to Fix Shared Mailbox Not Updating

If you are facing the issue of shared mailbox not updating in Outlook, then follow the steps given below to fix the issue:

1. Go to the File tab and click on Account Settings.
2. Select the account which is not updating and click on Change.
3. Uncheck the box next to Use Cached Exchange Mode and click on Next.
4. Click on Finish and then Close.
5. Restart Outlook and check if the shared mailbox is now updating.

Step 1: Check the Server

If you’re using Outlook and you notice that your shared mailbox isn’t updating, there are a few things you can check to try and fix the issue.

First, you should check the server status to make sure that there are no outages or disruptions that could be causing the problem. You can do this by visiting the Office 365 Service Health Dashboard.

If there are no reported problems with the server, the next thing you should check is your connection to the server. To do this, open the Control Panel and go to Network and Internet > Network Connections. Right-click on your connection and select Properties. Make sure that the “Connect automatically” option is checked and that your connection is set to “Work Network”.

If your connection is set up correctly and you’re still having trouble, the next step is to clear your Outlook cache. To do this, go to File > Options > Advanced. Under the “Outlook start and exit” section, click the “Clear Offline Folder Data” button. Once you’ve done this, restart Outlook and see if the shared mailbox is now updating correctly.

Step 2: Configure the Shared Mailbox

If the shared mailbox is not updating in Outlook, it could be because the mailbox isn’t set to synchronize automatically. To fix this, follow these steps:

1. In Outlook, click on File > Account Settings > Account Settings.
2. Select the email account that corresponds to the shared mailbox.
3. Under ‘Folder Options’, select ‘Sync Issues’.
4. Click on ‘Synchronize Now’.
5. Close the window and check if the shared mailbox has updated in Outlook.

Step 3: Auto-Sync the Shared Mailbox

If you’re using a shared mailbox in Outlook and you’re not seeing new mail messages, it’s likely because your mailbox isn’t set to auto-sync. Here’s how to fix that:

1. In Outlook, click the File tab.
2. Click Account Settings, then click Account Settings again.
3. Select the shared mailbox from the list of accounts and click Change.
4. Under Synchronization Options, check the box next to synchronization frequency (the default is every 30 minutes).
5. Click Save and then close the account settings window.

That’s it! Your shared mailbox should now be set to auto-sync and you should see new mail messages appearing in your inbox as they come in.

Step 4: Disable Download Shared Folders

If you’re using Microsoft Outlook and you’re noticing that your shared mailbox isn’t updating, there’s a fix for that. All you need to do is disable the “Download Shared Folders” caching feature in Outlook. Here’s how:

1. Open Microsoft Outlook.
2. Go to the File tab and click on Account Settings.
3. Click on Account Settings again.
4. Select the Exchange account and click Change.
5. Uncheck the box next to Download Shared Folders.
6. Click Next and then Finish.

After you’ve disabled this feature, your shared mailbox should start updating again in Outlook.

Step 5: Reconnect to Shared Mailbox

If you’re having trouble getting your shared mailbox to update in Outlook, there are a few things you can try. First, make sure that you’re still connected to the shared mailbox. If you’re not, you’ll need to reconnect it.

To do this, go to the File tab in Outlook and click on Account Settings. Then, click on the account that corresponds to your shared mailbox and click Change. Under Server Settings, make sure that the checkbox next to Use Cached Exchange Mode is checked. Then, click Next and Finish.

If you’re still having trouble, you can try refreshing your mailbox. To do this, go to the Send/Receive tab in Outlook and click on the Refresh All button. If that doesn’t work, you can try restarting Outlook.

If you’ve tried all of these things and you’re still having trouble, it’s possible that there’s an issue with the shared mailbox itself. In this case, you’ll need to contact your IT department or the person who manages the shared mailbox for help.

Step 6: Rebuild the OST File

If your shared mailbox is not updating in Outlook, you may need to recreate the OST file. This file stores your mailbox data locally on your computer, so if it becomes corrupted, you will not be able to see any new changes made to the shared mailbox.

To recreate the OST file, follow these steps:

1. Close Outlook and go to the following location on your computer. C:\Users\[your username]\AppData\Local\Microsoft\Outlook
2. Delete the OST file that is located in this folder.
3. Reopen Outlook and wait for it to recreate the OST file. This may take a few minutes.
4. Once the process is complete, open the shared mailbox and check for new updates.

Conclusion

If you’re having trouble getting your shared mailbox to update in Outlook, there are a few things you can try. First, make sure that you have the latest updates for Outlook installed. Next, check your account settings and make sure that the shared mailbox is set up correctly. If all else fails, contact your IT department or the person who manages the shared mailbox for help. With a little troubleshooting, you should be able to get your shared mailbox updating properly in no time.
