Disable Skype for Business Online integration




If you are using Skype for Business Online with Outlook, you may notice that it slows down Outlook performance.

  • Click on Options.



  • Click on Personal.

This way, you can access your emails faster and reduce the network traffic. To enable Cached Exchange Mode, follow these steps:



  • Open Outlook and click on File.



  • Click on Account Settings and then Account Settings again.



  • Click on the Email tab.



  • Select your Exchange account and click Change.



  • Check the box for Use Cached Exchange Mode and click Next.



  • Click Finish and restart Outlook.



Disable hardware acceleration

  • Open Outlook and click on File.



  • Click on Options.



  • Click on Advanced.



  • In the Display section, check the box for Disable hardware graphics acceleration and click OK.



  • Restart Outlook and check if the issue is resolved.



Move or delete some messages from the server




If you have a large number of messages on the server, it can take a long time for Outlook to download them. To speed up Outlook performance, you can move or delete some messages from the server. To do this, follow these steps:



  • Open Outlook and click on Send/Receive.



  • Click on Download Headers in the Send/Receive Groups drop-down list.



  • Select the folder that contains the messages that you want to move or delete from the server.



  • Select the messages that you want to move or delete from the server and right-click on them.



  • Select Move or Delete from the context menu and choose a destination folder or confirm the deletion.



Export to an Outlook for Mac archive file




If you are using Outlook for Mac, you can export your emails to an archive file to reduce the size of your mailbox and improve Outlook performance. An archive file is a separate file that stores your emails and other items. You can access it anytime by opening it in Outlook. To export to an archive file, follow these steps:



  • Open Outlook for Mac and click on Tools.



  • Click on Export...



  • Select Items of these types: Mail and click Continue.



  • Select a location to save the archive file and click Save.



  • Wait for the export process to complete and click Finish.



How to troubleshoot common Outlook problems

Sometimes, you may not be able to open Outlook at all. This can happen due to various reasons, such as a corrupted data file, a faulty add-in, or a damaged profile. To fix this problem, you can try these solutions:



  • Run Outlook in safe mode by holding down the Ctrl key while launching it. This will disable any add-ins or customizations that may be causing the problem. If Outlook opens in safe mode, you can disable or remove any suspicious add-ins as described above.



  • Repair your Office installation by going to Control Panel > Programs > Programs and Features > Microsoft Office > Change > Repair. This will fix any corrupted or missing files that may be affecting Outlook.

  • Reset the navigation pane by running the command outlook.exe /resetnavpane in the Run dialog box. This will clear any corrupted settings that may be preventing Outlook from opening.

Outlook send/receive errors

  • Check your Outlook data file and make sure that it is not corrupted or full. You can repair or compact your data file as described above, or delete some items from your mailbox to free up some space.



Outlook data file access denied




Sometimes, you may not be able to access your Outlook data file due to a permission issue. This can happen if you have moved your data file to a different location, or if you have changed your user account or password. To fix this problem, you can try these solutions:



  • Locate your Outlook data file by going to File > Account Settings > Account Settings > Data Files and note down its path.



  • Close Outlook and open File Explorer on your Windows 10 device.



  • Navigate to the folder where your data file is stored and right-click on it.

Cannot open Outlook attachments




Another common problem that you may encounter with Outlook is that you may not be able to open attachments in your emails. This can happen due to various reasons, such as a security issue, a compatibility issue, or a file association issue. To fix this problem, you can try these solutions:



  • Check the file type of the attachment and make sure that you have the appropriate program to open it. For example, if the attachment is a PDF file, you need a PDF reader like Adobe Acrobat Reader to open it.



  • Check the security settings of Outlook and make sure that they are not blocking attachments from opening. You can go to File > Options > Trust Center > Trust Center Settings > Attachment Handling and uncheck the box for Do not save encrypted files to disk.



  • Check the file association settings of Windows 10 and make sure that they are not corrupted or changed. You can go to Settings > Apps > Default apps and click on Choose default apps by file type.
