How Google Storage Caps Impact University Alumni Email

For years, universities made their alumni a simple promise: keep your school email address for life. Google Workspace for Education made that promise easy to keep with unlimited storage and no per-user fees. Then, in July 2022, Google changed the deal.

The change was straightforward but seismic: Google capped all education accounts at 100 TB of pooled storage per institution, shared across every user and every Google app. For schools with tens of thousands of alumni accounts sitting alongside active students and faculty, the math suddenly didn’t work anymore.

The storage cap isn’t the only change. Google has also tightened enforcement around inactive accounts, pushing universities to deprovision alumni who don’t log in regularly.

What This Looks Like on the Ground

Here’s a scenario playing out at universities right now — and it’s not hypothetical. We’ve heard versions of this story from IT leaders at schools across the country.

A large state university has around 55,000 alumni email accounts in Google Workspace. Over the past few years, they’ve already stripped alumni access down to the bare minimum — no Google Docs, no Calendar, no Drive. Just email. Even that is becoming unsustainable.

To manage storage, the school requires alumni to log in at least once every six months. Miss the window and your account gets deprovisioned. Here’s the problem: roughly half of deprovisioned alumni immediately request reinstatement, creating a revolving door of support tickets that never ends.

Meanwhile, the university is adding roughly 8,000 new alumni every year. The storage pool doesn’t grow, but the demand does. It’s a math problem with no good answer inside Google Workspace.

The Broader Picture: It’s Not Just One School

This isn’t an isolated case. As EdTech Magazine reported, universities nationwide have been forced to make difficult decisions about alumni accounts since Google’s storage policy took effect. Some schools gave alumni a six-month warning before cutting off their college-issued email address entirely.

The responses generally fall into three camps:

Cut alumni off entirely — The nuclear option. Universities simply stop providing alumni email, breaking a long-standing promise. Alumni lose their institutional address permanently.
Enforce aggressive deprovisioning — Keep the service but require regular logins to stay active. This creates a continuous cycle of support tickets and frustrated alumni.
Migrate to a dedicated forwarding service — Move alumni to a lightweight forwarding system that preserves their institutional address without consuming storage or requiring full mailbox licenses.

The Smarter Path: Keep Your Domain, Offload Your Alumni

Here’s what most universities don’t realize: you don’t have to migrate anyone to a new domain to solve this problem. Alumni can keep their original @school.edu address — the one on their resume, the one that gets them student discounts, the one they’ve used for years — while the university completely eliminates the storage and licensing burden.

The approach is elegant in its simplicity. Your Google Workspace (or Office 365) stays exactly as it is. When an email arrives for your domain, it does what it’s always done: checks for a local mailbox. If the recipient is a current student or employee, the email delivers locally. If the user doesn’t exist locally — because you’ve deprovisioned their Google account — the email routes to our forwarding service instead.

This works with Google Workspace routing rules, Office 365 transport rules and connectors, or organizational unit (OU) based routing — whatever your environment already supports. No DNS changes to your primary domain. No MX record modifications. No alumni migration communications.

Why This Beats a Subdomain Migration

Some schools jump straight to creating an @alumni.school.edu subdomain. That works, and we support it — but it’s often not the best first step. Here’s why:

Alumni want to keep their original address. It’s on their LinkedIn, their resume, their professional contacts. It’s the address that gets them educational discounts and university access. Changing it is a hard sell.
A subdomain migration requires communicating to every alumnus and getting them to update their address everywhere — a massive change management project.
Unknown user routing requires zero changes from the alumni perspective. Their email address stays exactly the same. They don’t even know anything changed behind the scenes.
You can always add an alumni subdomain later as an optional second phase — once the immediate storage crisis is resolved and you have time to plan a proper transition.

What You Actually Get

Immediate Storage Relief — Deprovision alumni Google accounts and reclaim storage instantly. No more alumni competing with active students and faculty for your 100 TB pool.
A Fraction of the Cost — Forwarding costs roughly $100 per 1,000 users per year. For a school with 55,000 alumni, that’s under $8,000/year — less than many institutions spend on a single enterprise software license.
Self-Service Portal Eliminates Support Tickets — Alumni verify and update their forwarding address through a simple portal — click a link sent to their personal inbox, done. No institutional authentication, no SSO headaches, no password resets, no six-month login requirements.
Enterprise-Grade Email Security — Full SPF, DKIM, DMARC, and ARC authentication. Enterprise spam protection. The same infrastructure that handles email security for government agencies and Fortune 500 companies.

How Other Schools Are Handling It

Some schools use unknown user routing to silently forward alumni email from their primary domain — alumni don’t even know anything changed
Others use organizational unit (OU) rules to separate alumni from active users, routing the alumni OU to an external forwarding service
A few retain alumni in their identity management system (Okta, Azure AD) for SSO-based email access — technically clean, but expensive and complex
Some eventually transition to a dedicated @alumni subdomain as a second phase, once the immediate crisis is resolved

The schools that solve this fastest are the ones that don’t force alumni to change their email address. They keep the domain, offload the accounts, and let a purpose-built forwarding service handle the rest.

The Bottom Line

Google’s storage policy change wasn’t malicious — it was a business decision. But it fundamentally broke the economic model that made “lifetime alumni email” possible for most universities. The schools that are solving this fastest aren’t asking alumni to change anything — they’re changing the plumbing behind the scenes.

If your institution is still running alumni accounts in Google Workspace — watching your storage pool shrink, processing reinstatement requests, and wondering when the next policy change will make things worse — the fix is simpler than you think. Your alumni keep their addresses. You reclaim your storage. The email just works.
