Can I Revert To An Earlier Version Of Outlook For Mac



Summary

A spate of recent updates caused problems in Outlook and the short-term fix is to uninstall the update; however, updates can’t be uninstalled from the Click-To-Run installations of Office, and almost all users have the Click-To-Run installation. Instead, you will need to revert to an earlier version. Reverting to a previous build number (from before the update) of Office 365 is possible but is very different from a msi-based installation. To revert to an earlier released version of Office 2013 or Office 2016 as an Office 365 installation, you must use a command line and specify the build number you would like to revert to.

By default, installations of Microsoft Office are configured to automatically update your Office installation when new updates are made publicly available. Occasionally, you may have to revert to an earlier version or build of an Office installation. For example, an automatic update may introduce unexpected behavior by one of your Office applications. In this case, you may want to revert to the previous version until a new version is released that addresses the issue you experienced.

Important: This article provides a list of recommended steps to revert to an earlier version of an Office 365, 2019, or 2016 installations. This article doesn’t apply to MSI versions of Office.

This guide will help you open, access, and import the mailbox items in Outlook for Mac (.olm) to Outlook for Windows with 100% precision and accuracy.

Microsoft Outlook email client can be used on both Windows and Mac. However, both platforms store mailbox data in different kinds of Outlook data files. Outlook on Mac stores the mailbox items in an .olm file, while Outlook on Windows keeps the mail items in OST or PST file.

The OLM file extension is specific to Outlook for Mac and it was introduced with Outlook 2011 for Mac. Since the OLM file is specific to Mac, it cannot be opened through Windows Outlook. Thus, if you want to access and open Outlook for Mac .olm file, you must convert the .olm file to .pst by using an OLM to PST converter software.

Steps to Convert OLM to PST

To convert OLM to PST, you first need to export the OLM file from Outlook for Mac. The steps are as follows,

In this method, an IMAP Server (Gmail in this case) is used as an intermediate mail server to sync and move the mail items in Mac Outlook (OLM) file to Windows Outlook. It is similar to using a storage device between two computers to transfer data.

The steps are as follows,

Step 1: Enable Gmail IMAP Settings

  • Open Web browser, go to Gmail.com and sign in to your Gmail account.
  • Open ‘Settings’ and click on ‘Forwarding and POP/IMAP’.
Revert
  • Then ‘Enable IMAP’ access and ‘Save Changes’.

  • Finally, click ‘Open Microsoft Outlook’

Step 3: Copy Mail Items from Mac Outlook Profile to Gmail Profile

  • After a successful Gmail sign-in, right-click on the Gmail ID and select ‘New folder’ from the options.
  • Name the folder ‘OLM Data’.
  • Now right-click on the email folder stored in the OLM profile of your MS Outlook for Mac, such as Inbox, and choose ‘Copy Folder…’

In the search, enter ‘OLM Data’ and then select the ‘OLM Data’ folder.

Click ‘Copy’. This will copy the mail items from Outlook Mac (OLM) folder to the Gmail folder that we created earlier and named as ‘OLM Data’.

After copying, wait for the Gmail server to finish the sync.

Step 4: Add Gmail Account to Outlook for Windows and Export PST

Once all the copied email items are synched, go to your Windows Outlook and sign in using the same Gmail ID.

Then use open the Outlook Import/Export Wizard to export the copied mailbox data in Gmail’s OLM Data folder to PST.

This way, you can export the OLM data to PST indirectly. However, it’s important to note that not all mailbox items can be copied. Also, there are several limitations of this method, which are as follows,

  • Data consistency problem and missing attachments
  • This process can take several hours to finish
  • You cannot sync or move more than 15GB data (max) via this method at once
  • The structure and formatting are lost
  • Data loss is also an issue

Thus, if you want to avoid all these issues, use the Stellar Converter for OLM software.
