As an existing customer and having already used the last version, will MS allow me to download the older version of Office that I already have? Or will I not beĪble to on this iMac? I have an old Office 2011 version but this is nothing compared to Office 365 and I have been using it for years. If my iMac should die or I replace the Hard disk and reinstall the OS to the same version. Will my Office 365 version installed on my iMac always work and be activated by Microsoft? MS are warning that it can't update my Office which is fine however I don't want the license removed as its now an old version? I am happy with the last version.Ģ. I can update to High Sierra as this is the last version supported on my iMac however my Adobe products then won't work so I don't want to do this.ġ. I have been having a warning appear in Office that it can't update to the latest version as my MacOS is not not supported. I have been with Office 365 for many a year and have an iMac 2011 and various other Windows 10 laptops.
