At times you may get an error while using ExMerge:
"Error configuring message service (MSPST MS) (MAPI_E_EXTENDED_ERROR) (CmapiSession::CreateEMSPSTProfile).
Error opening message store (MSEMS). Verify that the Microsoft Exchange Information Store service is running and that you have the correct permissions to log on. (0×8004011d)."
This can be due to incompatibility issues, the modified format of Outlook PST, PST privilege issues, corruption, etc. Sometimes the entire Exchange database can get corrupt due to the issues in ExMerge use.
In numerous scenarios, ExMerge encounters challenges when attempting to migrate mailboxes to PST files or the Exchange server, largely attributed to the limitations we’ve previously discussed. In such instances, it is advisable to consider employing a dedicated professional software solution capable of extracting comprehensive data from corrupted EDB files. One particularly well-regarded option for Exchange Recovery is the Kernel for Exchange Server tool. This versatile tool excels in efficiently exporting Exchange data to PST files and seamlessly migrating mailboxes to both live Exchange and Office 365 environments. In cases where you encounter error messages during or after using ExMerge, Kernel for Exchange Server can prove invaluable in gaining access to otherwise inaccessible mailboxes.
