The International Organization for Standardization is expected to announce the results of an Open XML vote on Wednesday.
Representatives from 87 countries had until Saturday night to submit their votes on whether the Office Open XML (OOXML) file formats should be certified as ISO standards.
The final tally was expected to be communicated on Monday. But a spokesperson for the ISO told Reuters that it will issue a press release on Wednesday to notify member countries first.
Microsoft on Monday issued a statement saying that it will not comment on the matter until Wednesday "out of respect for the standards process."
