If Outlook is stuck on Updating this folder in Shared mailbox on your Windows 11/10 PC, read this post to learn how to fix the issue. Some users are experiencing an issue where their desktop Outlook is not receiving new emails, while Outlook Online and mobile devices receive them without problems. The status bar in Outlook displays ‘Updating this folder‘ for hours, and sometimes emails appear after restarting Outlook.
This issue aligns with a known problem where shared mailboxes stop refreshing (automatically) for new emails, displaying the ‘Updating this folder’ message in the bottom bar. The issue can be confirmed by looking in the Sync Issues Synchronization Log of the primary Exchange account in your Outlook profile.
Beyond the primary issue, additional symptoms, such as receiving non-delivery reports (NDRs) when responding to a meeting invite, errors accessing shared calendars, and Online Archive not displaying the expected folders, can help identify or diagnose the problem.
Fix Outlook stuck on Updating this folder
If your Outlook is stuck on the Updating this folder in Shared mailbox message in Windows 11/10, use these solutions to fix the issue:
- Delete the corruption from the current profile
- Create a new Outlook profile
Before you begin, restart your computer and router and see if it helps.
1] Delete the corruption from the current profile
This method involves editing the Windows registry, so proceed with caution. We recommend backing up the registry first to ensure you have a safe copy of its current state. If an error occurs or changes you make cause issues, you may use this backup to restore the registry to its previous, working state.
Right-click the Start button icon and select Run. Type ‘regedit‘ in the Run dialog and press Enter. A User Account Control prompt will appear. Click Yes to continue opening the Registry Editor.
In the Registry Editor window, navigate to the following path (in the left pane):
Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Profiles
Locate the name of the Outlook profile that is having issues with the shared mailbox and select it.
Next, click the Edit menu on top of the Registry Editor window and select Find. Search for the registry key named ‘0102663e‘.
Locate this key in the profile where the parent key is just above the GroupStore folder. Right-click the 0102663e key and select Delete.
Close the Registry Editor and restart Outlook. Check if the shared mailbox is now updating correctly. If not, you need to create a new Outlook profile.

2] Create a new Outlook profile
A new profile resets all settings related to your email accounts, including the shared mailbox. This can clear up any corrupted or incorrect settings that might prevent the shared mailbox from syncing properly.
To create a new Outlook profile, follow these steps:
Type ‘control panel’ in the Windows Search bar and hit Enter. In the Control Panel window, set the view to ‘Small icons’ or ‘Large icons’. Click on Mail (Microsoft Outlook).
In the Mail Setup window, click on Show Profiles.
In the Mail window, you’ll see a list of existing profiles. Click on Add to create a new profile. Enter a suitable name for the new profile and click OK.
An Add Account wizard will appear. In the ‘Add Account’ wizard, choose Auto Account Setup and enter your email account details (your name, email address, and password). When prompted, enter your password again.
Click Next and let Outlook configure the account. Once Outlook successfully configures your account, click Finish.
In the Mail window, under ‘When starting Microsoft Outlook, use this profile:‘, select ‘Always use this profile‘ and select your newly created profile from the drop-down list.
Click Apply, then OK.
Close the Mail settings window and open Outlook.
If the shared mailbox is linked to your primary email account (such as through an Exchange or Office 365 account), it should automatically appear in your new profile after Outlook syncs with the server. Otherwise, add it manually using these steps:
Go to File > Account Settings > Account Settings. Select your email account and click Change.
Click More Settings, then go to the Advanced tab. Under Open these additional mailboxes, click Add. Enter the name of the shared mailbox and click OK.
The shared mailbox should now appear in your Outlook folder list in the left pane and Outlook should no longer be stuck on the ‘updating this folder’ message.
I hope this helps.

Why is my Outlook stuck on updating?
Network issues, corrupt Outlook profiles, outdated or corrupt add-ins, conflicts with other apps such as security software, incorrect email settings, low mailbox storage, an oversized local cache (OST), and several other factors can prevent Outlook from synchronizing Inbox or Outbox emails with the Exchange server, leading to Outlook being stuck on updating folders.
How do I force Outlook to update a shared mailbox?
To force Outlook to update a shared mailbox, you can manually synchronize it by going to the ‘Send/Receive‘ tab and selecting the ‘Send/Receive All Folders‘ option. Additionally, you can reset the local cache by disabling and then re-enabling Cached Exchange Mode, or by deleting the local OST file to force Outlook to rebuild it. If these methods don’t work, creating a new Outlook profile might help resolve the issue.
