Resolving error message “This database cannot be read due to an invalid on disk structure.”

While working with the Lotus Notes application, you may receive error messages. Usually, the reason for the occurrence of different errors is the corruption of database. Along with, database corruption the internal settings are also one of the main reasons that results in different errors. In such situation, you need to apply different utilities, such as Fixup, Compact, update and NT Check Disk utilities. But after using these utilities, some another exceptions may also appear and it's not sure that you will get proper results. However, for better results a Lotus Notes Recovery software is also one of the most prominent options that Recovers Lotus Notes database.

To illustrate above problem consider the following example. When you try to send mail from the Lotus Notes application an error message appears on the screen. On every attempt to send mail from Lotus Notes mail application you will receive below error:

“Server Error: This database cannot be read due to an invalid on disk structure”.

Mail that you try to send is shown to be successfully sent by your mail account, but still an error message will be prompt.


When Sent folder is corrupt, and bad spot on drives results in the error: “This database cannot be read due to an invalid on disk structure.”

(4.2) Remove the problem database from the workspace, by right clicking on the icon and selecting “Remove from workspace”.

(4.3) Re-add the database by clicking on the doclink.
