Exchange is currently in recovery mode error denotes that MS Exchange and MS Outlook are in recovery mode. In such a situation the user can choose between two options Online and Offline Mode. If you click on Connect using the online mode, which means you can access the Exchange Server, but not allowed to access the old OST file. In the offline mode, you can access old OST file and the data, but can’t access the Exchange Server.
In this situation a new OST file will be made in Outlook and the old OST file will be kept on the local machine.
The MS Outlook 2003 and later versions introduced a new feature Cached Exchange Mode. In this mode, MS Outlook keeps a duplicate copy of the OST file on the local machine, ensuring the items that are as of now on the Exchange Server are constantly replicated. This ensures synchronization between Exchange server and Outlook in offline mode.
Note: Please keep a backup before implementing these methods.
Method 1: Disable Cached Exchange Mode
Method 2: Create A New Profile
You can also use OST to PST tool to convert inaccessible OST files into PST file format that are easily importable by Outlook.
