Limitations of G Suite Sync for Microsoft Outlook

The G Suite Sync for Microsoft Outlook is useful to sync your data. However, it also has issues that you should know.

  • When syncing large mailboxes, many users face slow synchronization during the process. Having a large mailbox takes hours and takes a lot of disk usage, memory, and CPU.
  • GSSMO makes your data in a local Outlook data file (OST). It consumes a lot of disk space, slows down your Outlook performance, and causes freezing issues.
  • This is not a reliable solution, as you may face calendar sync issues like recurring events not syncing properly, time zone mismatch, or duplicate calendar entries.
  • You will not get full advanced Outlook features, as it does not support all functions like Outlook public folders, Rich Text Format emails, certain Exchange-specific features, etc.
  • It is not available for Mac systems. So, you can only use it on a Windows computer.
  • You may face many sync issues because of sync conflicts. Also, it does not sync the data in real-time, which make it difficult to handle your data in Outlook.
  • GSSMO is not designed for migration purposes. It only syncs data that allows you to view your Google data in Outlook.
  • You cannot sync multiple accounts. So, this tool is not suitable for handling multiple accounts.

There are various problems one can face when using this tool. But there are ways that you can fix the problem.
