The world of online data storage, and specifically email archiving, has changed immensely in the last few years.
When Exchange Online was announced on June 3rd, 2015, it promised a “truly bottomless archive”. So long as the necessary licenses were in place, Office 365 E3, Exchange Online, or Exchange Online Plan 2, mailboxes would never run out of storage.
At least, that was the initial pitch.
Unfortunately, the phrase “truly bottomless archive” hasn’t totally held up.On November 1st, 2021, Microsoft has announced they'll begin enforcing a cap on their unlimited archiving to 1.5 TB.
