Google has announced a new storage policy for all institutions using Google Workspace for Education editions which will take effect in July 2022. This means the unlimited storage offered to qualifying schools and universities for free by Google will come to an end.

HKU Connect users are requested to reduce their total storage of to within 1TB by end of 2021. This is to ensure they can continue accessing their HKU accounts after a quota limit will be imposed by Google in early 2022.

Please note that Google does NOT offer a pay option for individuals to purchase additional storage for their school accounts using Google Workspace for Education editions.

Before you start any data migration, please read the following notes:

Note 1: You are recommended NOT to transfer your emails UNTIL the account migration date in June/July 2022 to avoid possible issues in synchronizing the emails caused by multiple data transfers.

Note 2: For graduates, please reset your graduate email account password by clicking here.  If you are unable to recall your username or password, please click here.

This is a one-off action only.  You need to complete the password reset before your first-time login to HKU Microsoft OneDrive.
