How do the best AEC firms get engineers to file project emails?
The firms with the strongest grip on project email have stopped asking engineers to change their habits. They've changed the system instead - embedding tools like Ideagen Mail Manager directly inside Outlook so filing happens automatically rather than relying on manual discipline. That's the single biggest difference between the firms consistently reaching high adoption and the majority who still can't find their own project correspondence when it matters.
Most AEC firms can’t find their project emails when they need them
Ideagen's 2022 research across 507 AEC leaders found that:
- 87% were at least somewhat concerned about project information not being readily available and visible
- 51% regularly need to retrieve information from past projects
- Only 44% required employees to file project emails to a central location
- One in three businesses lose critical project information when staff leave
More than half the industry regularly needs to find old project emails. Less than half are actually filing them anywhere findable. That's not a process gap - it's a structural exposure that gets worse with every project completed and every person who leaves.
A $90 million project where the other side had your emails and you didn't
The CEO, David Wesemann, at Spectrum Engineers described what happened on a $90 million resort project before their firm started using Ideagen Mail Manager. The firm received a subpoena to produce every email on the project. Some of the people involved no longer worked there. He went around trying to gather correspondence from various filing systems. In his words:
"I think I did a pretty good job. But at the end of the day when we delivered those emails over to the other party, they were able to produce emails that were sent from our office that we didn't have in that batch. And so it became a really critical issue for us and that was the point where I said we have got to get control of this."
A subpoena. Departed staff. Tens of thousands of emails. A thorough search that still missed things. That's not a careless firm - that's any firm relying on personal inboxes as their filing system.
The people with the most valuable emails are the least likely to file them
Every AEC firm has tried the same playbook: issue a filing policy, build an Outlook folder structure, run a training session. Compliance stays high for about three weeks, then collapses.
Ideagen's 2024 State of Tech Adoption and Collaboration in AEC research across 188 senior IT decision-makers explains why. Two-thirds (66%) agreed their end users bend IT rules to be more productive. Sixty-seven percent said emails are filed inefficiently.
And the people most likely to ignore the policy aren't juniors - they're directors (44%) and senior management (38%).
The people generating the most commercially sensitive project correspondence are the least likely to file it. Not because they don't care, but because the filing process adds friction to every hour of their actual work. Given the choice between filing properly and getting on with the project, they choose the project. Every time.
This is why training-led approaches fail. You can't train away friction. You can only remove it.
How do you get project teams to actually adopt email filing?
The firms that have solved this embedded the filing mechanism inside Outlook itself. Ideagen Mail Manager uses machine learning to learn your team's filing behaviors and prompts you to file each email to the right project folder in SharePoint or your DMS with a single click. No complex folder navigation. No saving emails as .msg files. No metadata forms.
Filed emails can be automatically removed from your inbox, keeping it clean without losing anything. And when you need to find a specific email or attachment months or years later, Mail Manager's search brings it back in seconds across your entire project archive.
The result across firms like WSP, Ramboll, and Arup: adoption holds because filing stops costing people time. It's not that engineers suddenly care more about filing. It's that the system no longer punishes them for doing it.
The difference matters across the business:
- New team members can access the full project correspondence history from day one
- When someone leaves, their project knowledge stays with the firm - not locked in an archived inbox
- When anyone needs to find a specific email, they search once and get the answer in seconds, not hours
Ideagen Mail Manager now supports over 100,000 users across 3,500 businesses worldwide. The firms getting this right aren't the ones with more disciplined engineers. They're the ones that stopped relying on discipline altogether.
