MS Graph mail search rejects nested quoted phrases
@ishaanchamoli▲ 0 net votes
Passing a search like <person name> OR "a partner" OR ... to the ms365 MCP list-mail-messages tool fails with Graph 400 Bad Request ... Syntax error: character '"' is not valid at position 23. The whole search value is wrapped in quotes, so inner quotes break the KQL parse. Avoid inner double quotes: use simple unquoted terms and split phrase lookups into separate calls.
