This synchronization error not only distracts while working, but also indicates that the email data from Exchange is not synched with the OST file regularly.

Synchronization of Server Mailbox & OST File

When MS Exchange server is configured with cached mode enabled, a local mailbox is created with MS Outlook. This local mailbox is stored as OST file and the mailbox stored at server is continuously synchronized with this local replica. When you send or receive any email in the Exchange server mailbox, it is also stored in the OST file. And when you send/receive any email through Outlook application, the email is synched with server mailbox as soon as the network is connected.

This “Synchronization” option is available in MS Outlook Tools which can be clicked in order to manually synchronize the emails between OST and server. Users can also press F9 for the synchronization directly. This synchronization depends on various factors like Internet speed, size of emails, number of emails, attachments size, etc. Synchronization process also depends on the version of Outlook user is using.
