Compact Lotus Notes Database
When we delete some large files and attachments from Lotus Notes, the database space becomes free. This free space, however, remains unusable. This unusable free space, also known as white space, is often the major cause of IBM Notes database size limit exceed. To avoid this situation, we can compact the database that will ultimately remove all the white space from the database. The method of compacting database are:

2. Click File and then, select Database.
3. Here, select Properties from the drop down menu.
4. Now, Database Properties dialog box will appear. Click on the second tab of that box.
5. Click % button. You can see the current compression ratio now.
6. Click Compact if the percentage ‘%’ is less than 90%. Now the database will get compact.

Removing unnecessary emails from IBM Lotus Notes account is the best way to keep the database free. Users should start this practice of deleting emails from both Inbox and Sent Items to free the database.

Managing Email Attachments
Large email attachments might be the reason IBM Notes database is running out of space. Delete emails with attachments that you do not require. In case of important attachments, you can always download them to your system first and then, delete. This will free database space.

Archive Rarely Used Documents
Archiving is another option then will benefit the users in terms of saving the database space. Emails, that we do not usually need but might become useful in future, can be archived instead of deleting. Lotus Notes frees the database and saves the archived files in a new storage location. This method can also resolve the problem ‘Lotus Notes database size exceeds quota limit’.

2. Now, select User Preferences >>click Mail.
3. Find out Save Mails That You Send option in the Sending section. From the drop down menu, select Always Prompt.
