MAPI error MAPI_E_STORE_FULL

Question

I get the MAPI_E_STORE_FULL OLE Error when I am trying to open a message item from store(mapistore.OpenEntry).

On going through some google search pages I found that this OLE error may be a result of using old style pst files(pre 2003 versions) if it has reached the size of 2 GB.

But again I am just trying to open the message item and not writing anything into the store. I am using MAPI interface through Python to read the contents of a message store. I am really confused. Is this error expected in case of reading the pst??

Answer 1

You PST file is almost 2GB bit and you're using the old PST file format. That supports max. 2GB per file. Microsoft explains here how to convert it into the new format.

Use MFCMapi utility to open the store. You can isolate the problem with help of this tool.MFCmapi
