How to fix the error Outlook not updating inbox automatically?

Content

Since some weeks everyday another user calls and tells me he doesn't get mails. After hitting the update folders button or closing and reopen outlook new mails get visible. Reinstalled office, deleted ost, made a ne outlook profile. By taking proactive steps to manage your mailbox, you can prevent issues related to storage limits and ensure that your Outlook inbox continues to update properly. When you synchronize your Exchange mailbox to an Offline Folder file (.ost), the Outlook status bar never shows higher than 3.99 GB when a folder is being updated.

Check Disk Space

Please make sure you set both the ClientAuthenticationMethod to NTLM and IISAuthenticationMethods to Basic,NTLM (and Basic,NTLM,Negotiate for Exchange 2013). Here is a comprehensive list of possible causes for the error ‘Outlook inbox not updating’ and how they can affect the working of Outlook. By applying this sort order (which is default in Outlook), you'll be always seeing the most recent communications first. If the Inbox and Outbox folders start updating, you can switch back to Cached Exchange Mode. A vast community of Microsoft Office365 users that are working together to support the product and others. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

If the antivirus program isn't Outlook friendly, you may experience certain issues while using Outlook. To check whether the antivirus app is preventing Outlook from updating the Inbox or Outbox folder, temporarily disable the antivirus program and restart Outlook. If the issue is resolved, exclude Outlook processes, Outlook data files, Outlook sync help from FixTechGuide and folder locations from your antivirus program. The SVC record had to be updated in DNS, which was the cause of the autodiscover issue in my last post.

Internet connectivity issues

Client logs and RPC logs on Exchange just show frequent connections and disconnections for the affected user, and I can’t find any other errors. Open RPC connections on Exchange during business hours is about 300 which seems manageable. If some of these Exchange PowerShell commands error out, don’t worry, these are to provide everything from Exchange 2013 back to 2007. In this guide, we’ll take you through simple, repair corrupted OST in Outlook step-by-step methods to identify the issue and fix Outlook’s sync problem efficiently. Free up your time from routine correspondence with personalized, easy-customizable, dynamic email templates.

Check Outlook Email Account Settings

Every affected user has recently been upgraded to Windows 7 64-bit, while I have not had any 32-bit client users report any similar issue. So all signs are pointing to the individual client but I can’t figure out what it is. With automatic send/receive enabled and properly configured, you can maintain regular synchronization between Outlook and the email server, keeping Outlook stuck updating folders solution your Inbox up to date. I think this problem is resolved, although since it is so intermittent it may be a while before I’m sure. MTU was set to 1514 on the Exchange server rather than the typical 1500.

Reset or repair new Outlook

Per the article below I updated the Ethernet drivers on the the server to the most recent version and the MTU was automatically set to 1500. Not sure why only certain machines were affected but at this point I’m keeping my fingers crossed. Turning off cached Exchange mode works, but the connection seems to be spotty as Outlook will freeze up after a while. Rebooting, deleting the OST and/or mail profile does not have any effect. Things work well for a number of days or weeks but the problem reoccurs eventually.

If you then allow the synchronization process to fully synchronize the folder, the status bar may eventually indicate the following text. You can set it to a higher number if you desire / need but it works for a user who has 14 mailboxes. The only other thing that I experienced was the ‘bitness’ of some outlook plugins or their application via gpo. Please provide the output from the following commands so that we can check to make sure your settings are set up correctly.

Why is my Outlook Inbox not updating?

If you are running out of storage, make some space by moving some files from the storage to another folder or volume. You may also archive the OST mailbox to reduce the mailbox size. I reimaged the machine of the lone person that continued to have this problem and Outlook has been working OK for the time being. However, the problem cropped up again yesterday for a new user. The connection to Exchange drops, reconnects every few seconds or so until eventually the issue clears up. Interestingly, during this time I was unable to connect to OWA using a different mailbox on the affected client computer.
