Resolving “Outlook cannot log on” Error While Synchronizing with Exchange Server

Are you working in a collaborative messaging environment of Microsoft Exchange Server? Have you configured Microsoft Exchange Server in Cached Exchange Mode? If yes, then you must have faced some kind of synchronization issues, while synchronizing your OST (Offline Storage Table) file with Microsoft Exchange Server database. In Cached Exchange Mode, a copy of your Exchange mailbox is stored locally on client hard drive in the from of OST file. When you convert to Exchange Server, OST file is converted to PST after synchronization. When synchronization fails, you need to manually convert OST file to PST to update the OST file and access Exchange Server mailbox.

When you attempt to connect to Microsoft Exchange Server using MS Office Outlook 2007, the synchronization process fails. When you click the Check Name option for verifying the settings in E-mail Accounts, you encounter the below error message:

“Outlook cannot log on. Verify that you are connected to the network and are using the proper server and mailbox name. The connection to the Microsoft Exchange Server is unavailable. Your network adapter does not have a default gateway.”

Furthermore, you may encounter the below error message while connecting to Microsoft Exchange Server 2003 with Microsoft Office Outlook 2007 using RPC over HTTPS:

Cannot start Microsoft Office Outlook. Cannot open the Outlook window. The set of folders cannot be opened. The attempt to log on to Microsoft Exchange has failed.”

After this behavior, the synchronization process fails and you cannot connect to MS Exchange Server. At this point, OST PST conversion becomes need of hour to access Exchange Server mailbox.

Root of the problem:

You may come across this problem due to any of the below reasons:
• You do not have default gateway configured on your Microsoft Office Outlook 2007 client computer.
• The Exchange Server user profile is damaged.


Try out the below methods to Convert OST to PST by fixing this problem:
