One of the biggest improvements in Outlook for Mac for Office 365 compared to Outlook for Mac 2011 is that the database has been completely replaced by SQLite. If you’ve used Outlook for Mac 2011 previously, you may have ran into issues with database corruption and are familiar with having to manually rebuild the database.
With Outlook for Mac for Office 365, you will no longer need to manually perform database rebuilds. This is due to several reasons:
- The reliability and stability of the new database have been greatly improved, so the likelihood of database issues occurring is lower overall.
- Outlook will perform a silent recovery in the background for small database issues, no longer requiring database rebuilds.
- For larger database issues where a silent recovery is not possible and a database rebuild is necessary, Outlook will prompt the user to repair the database to fix the problem.
Because of these changes, the ability to manually start a database rebuild is not available in Outlook for Mac for Office 365. This will help reduce time spent on rebuilding the database for issues that truly are not caused by database problems, thus a database rebuild is not necessary.
For small database issues, such as missing or corrupt data, Outlook performs a silent recovery in the background by syncing the necessary data from the server or by reconstructing the corrupt file from data in the index. When this occurs, the user is not notified and likely won’t be aware this is occurring in the background at all.
For larger database issues, Outlook will notify the user with steps on how to recover the database. In this scenario Outlook will alert the user, force Outlook to restart, rebuild the database, and load the rebuilt database.
